Why Do Onions Make Us Cry?

Onions are one of the most common staple foods around the globe. Ironically, for a vegetable so delicious, they can often be tear-jerkers.

Read on to learn why onions cause your eyes to tear and sting, and what you can do to minimize discomfort.

Why Does Cutting Onions Cause Tearing?

Onions produce a sulfur compound called propyl sulfoxide that is stored in the cells of the onion bulb (the part of the onion we eat). Onions grow underground, where they can be eaten by all types of creatures. This odorous sulfuric compound acts as a deterrent to small animals with big appetites.

When one slices into an onion and breaks open its cells, the sulfur compound is released and mixes with the moisture in the air — turning it into smelly and irritating sulfuric acid. When this chemical rises up and comes in contact with your eyes, it stings!

To keep your eyes from potentially being damaged from this chemical exposure, your brain triggers your eyes to tear and flush out the irritating gas particles. Once enough tears have flushed out the sulfuric acids particles from the eye, clear vision and comfort is usually restored. Although your eyes may sting and feel unpleasant, symptoms are temporary and the sulfuric acid won’t damage your eyes.

How Can I Reduce Eye Discomfort When Chopping Onions?

Most experienced chefs will tell you that chilling your onions in the fridge for at least 30 minutes before slicing them will reduce the amount of tearing they cause. Propyl sulfoxide escapes slower in cooler temperatures, reducing the amount of sulfuric acid in the air.

You can also try cutting the onions at arm’s length, or direct the odorous air away with a small fan. Some say that chopping onions immersed in water also helps. Another option is to wear kitchen goggles to protect your eyes.

Furthermore, try to use fresh onions whenever possible. The longer an onion has been stored, the more likely it will induce tearing and discomfort. Try to avoid slicing near the root end of the bulb, as that area has the highest concentration of sulfuric compounds.

15 Things You Do That Can Harm Your Eyes

Eye health isn’t just about going for that yearly eye exam. Certain actions you take (or don’t take) in your daily routine can also have drastic effects on the health of your eyes and vision. Here’s our list of 15 things you may be doing that could pose damaging risks to your eyes.

It’s important to note that before changing any of your habits, consult with a medical professional to make sure they are right for you and your overall health.

1. Smoking

We all know that smoking can cause heart disease and cancer, but its effects on the eyes are far less known to many. The truth is that smoking can actually lead to irreversible vision loss by significantly increasing the risk of developing macular degeneration, cataracts, glaucoma, and diabetic retinopathy. It can also cause dry eye syndrome. If you are a smoker, do your eyes (and body) a favor and try to kick or reduce the habit.

2. Not Wearing Sunglasses

Exposing your eyes to the sun’s harmful UV radiation can damage the eye’s cornea and lens. Overexposure to UV rays can also lead to cataracts and even eye cancer. That’s why it’s important to always wear 100% UV-blocking sunglasses while outdoors, all four seasons of the year. Always check the sunglasses have FDA approval.

3. Sleeping with Makeup On

When you sleep with eyeliner or mascara, you run the risk of the makeup entering the eye and irritating the cornea. Sleeping with mascara on can introduce harmful bacteria to the eye and cause an infection. Abrasive glitters and shimmery eyeshadow can scratch the cornea as well. Be careful to remove all makeup with an eye-safe makeup remover before going to bed.

4. Buying Decorative Contact Lenses Without a Prescription

Although ordering decorative lenses without first visiting your optometrist may sound more convenient, purchasing them without a prescription isn’t worth the long term risks. Decorative contact lenses are sometimes made by unlicensed manufacturers who tend to use poor-quality or toxic materials that can get absorbed through the eyes into the bloodstream. They also may contain high levels of microorganisms from unsanitary packaging and storage conditions.

5. Not Washing Your Hands Thoroughly

Frequently washing your hands helps to reduce the possibility of bacteria and viruses entering the eye. Pink eye (conjunctivitis) and corneal ulcers are common eye conditions that can be caused by bacteria, viruses, fungi, or parasites. When washing your hands, be sure to use warm water, soap, and thoroughly wash in between each finger and over the entire palm area. If you plan to insert or remove your contact lenses, wash and then dry your hands completely with a lint-free cloth or paper towel.

6. Overwearing Contact Lenses

Wearing contact lenses for longer periods of time than intended can lead to inflammation of the cornea (keratitis), conjunctivitis, eyelid swelling, and contact lens intolerance. Always follow the recommended wear time as instructed by your optometrist.

7. Being Nutrient Deficient

Poor nutrition can cause permanent damage to the visual system. Try to include lots of nutrient-rich fruits and vegetables in your diet, along with adequate amounts of Omega-3. Some of the best vitamins and nutrients for eye health include Vitamins A, C, E, lutein, zeaxanthin, and zinc.

8. Using Non-FDA Approved Products

Whether it’s eyebrow enhancers, eye makeup, or eyelash growth serums, always choose products that have been FDA approved and/or meet government safety regulations. Non-approved products have been known to cause infections or allergic reactions in or around the eye area.

9. Not Cleaning Your Contacts Properly

If you are wearing contact lenses that need to be replaced once every two weeks or once a month, maintaining the highest level of contact lens hygiene is essential. Optometrists will tell you that a common reason patients come in to see them is due to an eye infection from contact lenses that haven’t been properly cleaned or stored. Some patients use their contact lens cases for too long, which can also cause eye irritation. To avoid eye infections, carefully follow your eye doctor’s instructions on how to clean, store, and handle your contact lenses.

10. Showering or Swimming with Contact Lenses

There is a significant amount of bacteria that can be carried in tap water and swimming pools. For this reason, it’s important to make sure that water and contact lenses don’t mix. If you need vision correction while swimming, it may be worth investing in a pair of prescription swimming goggles.

11. Not Following Medication Instructions

When it comes to eye disease, following the medication instructions is crucial. Forgetting to insert eye drops, or administering the incorrect dosage could dramatically reduce the effectiveness of treatment, or even do harm. Speak with your eye doctor if you’re not sure about when or how to take your medication.

12. Not Taking a Holistic Approach

Your eyes are just one part of the whole system — your body. Ignoring health conditions you may have, like high blood pressure or elevated blood sugar, can pose serious risks to your eyes.

13. Not Wearing Protective Eyewear

Shielding your eyes with protective glasses or goggles while working with potentially sharp or fast-moving objects, fragments or particles (wood working, cutting glass, welding, doing repairs with nails, certain sports) is the best defense against eye injury. In fact, 90% of all eye injuries could have been prevented by wearing protective eyewear.

14. Using Unsafe Home Remedies

Some might think that because something is “natural” that it is safe for use around the delicate eye area. Home remedies, like using breastmilk to cure pink eye, could introduce harmful bacteria to the eye and cause infection. If your eyes are giving you trouble, make an appointment to see your local optometrist.

15. Skipping Your Recommended Eye Exam

Your eye doctor will advise you how often you need to come for an eye examination. Adults should visit their eye doctor at least every year for a comprehensive eye exam to determine whether their optical prescription is up-to-date, and to check for the beginning stages of eye disease. Catching eye diseases in their early stages offers the best chance of successful treatment and preserving healthy vision for life.

The Surge In Cosmetic Procedures During COVID Raises Eye Health Concerns

COVID-19 has indirectly impacted eye health in ways that few would have anticipated. With many classrooms, business meetings, and hang-outs being relocated to virtual settings like Zoom and FaceTime, people are spending more time scrutinizing other people’s faces — and their own.

For some people, the more time they spend watching themselves in the thumbnail, the more time they focus on real or imagined imperfections and features that make them feel insecure.

In fact, plastic surgeons and cosmetic doctors all over the world are reporting something called the ‘Zoom Boom’ — the recent surge in cosmetic procedures to perfect ‘Lockdown Face.’ Yep, it’s a thing.

What many don’t realize is that cosmetic facial procedures can pose serious risks to eye health and vision, and in some cases result in serious eye damage or vision loss.

While opting to undergo a cosmetic procedure is a personal choice that each individual should make for themselves, a fully informed decision requires a visit to your eye doctor. Also, those interested in having a cosmetic eyelid lift should consult with a reputable oculo-plastic surgeon who has experience in this particular procedure.

How Can Cosmetic Procedures Impact Your Eyes?

Before undergoing a cosmetic facial procedure, it’s important to know which procedures pose potential risks to your eyes and vision.

Eyelash Extensions

The adhesive used for eyelash extensions has been known to cause allergic lid reactions, infections, styes, and dry eye. Eye doctors unanimously agree that eyelash extensions should be the last resort for those who want fuller, thicker lashes.

Additionally, the addictive nature of eyelash extensions make them particularly risky. A side effect of lash extensions can be reduced eyelashes, which often drives the individual to have this procedure done repeatedly.

A safe alternative to getting eyelash extensions is using a medication called Latisse. This eyelash enhancing product can be prescribed by your eye doctor and may reduce the need for false eyelashes or extensions.

Laser Procedures

Lasers are used for various cosmetic procedures due to their high efficiency and accuracy. However, exposing the naked eye to a laser beam can be dangerous.

All laser procedures should be performed while the patient wears specialized goggles or corneal shields for protection. If the procedure is performed by an unlicensed individual, there is a much greater chance that effective eye protection won’t be used.

A study published in The Journal of Clinical and Aesthetic Dermatology found that ocular injuries can occur even when protective shields are utilized correctly.

Episcleral Tattoos

This procedure is the tattooing of the whites of the eye. Dye is injected beneath the conjunctiva and into the sclera (the white of the eye) to make it appear the desired color.

Episcleral tattoos can cause headaches and severe light-sensitivity, and increase the risk of eye infections, conjunctival hemorrhaging, and permanent vision loss.

Botox Injections

Botox injections are one of the most popular cosmetic procedures offered today, but they can harm eye health and vision when injected around the eye area.

Some common complications include allergic reactions, blurred vision, and droopy eyelids. Most of these reactions are temporary, but if symptoms persist and if blurred vision is prolonged, see an eye doctor immediately.

Always choose a qualified and licensed doctor to perform the procedure.

When to Visit Your Optometrist

If you are considering having any facial or eye procedures done, speak with your optometrist about how to keep your eyes safe during the process.

An eye exam with Dr. Lowy will determine the state of your eye health and what risks would be involved with the procedure you want.

If you’ve already undergone a cosmetic procedure or surgery and are experiencing any eye health or visual symptoms, call Lowy & Sewell Eye Care in for a prompt eye exam.

We want you to feel confident in the way you look, while keeping your eyes healthy and safe. Call Lowy & Sewell Eye Care to schedule your eye exam today.

Tips to Relax Your Eyes

Do your eyes hurt after spending a significant amount of time reading, playing video games, driving, or staring at a screen? These visually intense activities can sometimes be hard on the eyes, causing uncomfortable symptoms like headaches and blurry vision. Other symptoms of eye strain can include light sensitivity, neck and shoulder pain, trouble concentrating, and burning or itchy eyes.

Fortunately, preventing painful computer vision syndrome and eye fatigue symptoms can be as simple as trying a few of these eye exercises. To learn more about digital eye strain and discover the best relief options for you, call Lowy & Sewell Eye Care at 905-738-6680 and schedule an eye exam with Dr. Lowy.

Relax Your Eyes with These Supportive Techniques

Many of these exercises are designed for computer users. Eye strain resulting from long drives, reading, or other activities, can be alleviated by modifying some of these recommendations.

The Clock Exercise

The clock exercise relieves strain on overworked eye muscles and can help you avoid headaches and eye pain, among other symptoms. Begin the exercise by imagining a large analog clock a few feet in front of you. Keep your head still and move your eyes to the imaginary 9, then to the imaginary 3.

Keep moving your eyes to the opposite pairs on the clock — 10/4, 11/5, 12/6, and so on. Hold your gaze for a second or two on each number before moving on to the next one. Continue doing this for 4-5 minutes.

The 20-20-20 Rule

The 20-20-20 rule helps you avoid dry eyes and eye strain by giving your eyes frequent breaks. After about 20 minutes of screen time or doing close-up work, focus on an object at least 20 feet away for 20 seconds. This gives the eyes a much needed rest and helps them relax. There are also free apps available that provide pop-up reminders that notify you when it’s time to shift your gaze.

Screen Ergonomics

The American Optometric Association recommends placing computer monitors 20 to 28 inches, or 50-70 cm, away from your eyes and the top of the computer should be at eye level or right below for optimum eye comfort. Glare filters can reduce the amount of glare produced by digital devices and improve your viewing experience.

Poor sitting posture can also contribute to eye strain. Your chair should be situated so that your feet are flat on the floor, or use an angled footrest for additional comfort.

Optimize your Eyewear

Since regular prescription lenses or glasses may not adequately meet your visual needs for lengthy computer use, you may benefit from wearing computer glasses. These prescription glasses are customized to your needs and also reduce glare and block blue light.

 

You don’t have to live with the discomforts of eye strain. If symptoms persist, it may be time to visit Lowy & Sewell Eye Care and get the relief you seek. Call our office to schedule a convenient eye doctor’s appointment.

 

How Can My Child’s Myopia Be Corrected?

At Lowy & Sewell Eye Care, we help children like yours achieve clear and comfortable vision, so they can succeed at the important things in life.

Methods of Myopia Correction

Contact Lenses

Contacts can be a great choice, especially for physically active children or teens who don’t want to worry about breaking or misplacing their eyeglasses. In some cases of very high myopia, contact lenses can offer clearer vision than glasses.

Corrective contact lenses are usually placed in the eyes upon waking and removed at night before bedtime. There are several types, including: soft contacts (daily disposables, extended wear) and rigid gas permeable (hard) lenses. Navigating through the differences between them can be daunting. Fortunately, if you’re located in Concord our eye doctor will be happy to guide you. Speak with Dr. Lowy to determine whether your child is ready for contact lenses.

Prescription Glasses

Glasses are a popular choice among our younger patients. Choosing from an array of styles makes the process fun and exciting! Allowing the children to be active participants in selecting their eyewear increases the likelihood that they’ll actually wear them. There are strong, flexible and resilient frames which look great and are comfortable too.

The optician can customize the lenses with additions and upgrades like impact-resistant or shatter-proof materials, scratch-resistant and anti-reflective coatings, UV filters, and transition lenses that darken in the sun. For those requiring vision correction for distance and near, we also offer bifocal or multifocal lens prescriptions.

We Can Help Correct Your Child’s Myopia

If you’re located near Concord, Ontario, an eye exam with our optometrist can determine your child’s exact prescription, and give you the opportunity to receive answers to any questions you may have about your child’s eye health and vision. Progressive myopia, where a growing child’s prescription continues to worsen, is why it’s important for myopic children to undergo eye exams at least once a year.

At Lowy & Sewell Eye Care, our friendly and knowledgeable staff will be happy to recommend the most suitable method of correcting your child’s myopia to meet his or her individual needs. Thanks to the wide range options available, your child will walk away with eyewear that will not only enhance his or her style but will also be a boost of confidence.

Let us help your child see the world in a whole new light. To schedule your child’s annual eye exam or if you have any further questions, contact Lowy & Sewell Eye Care at 905-738-6680 today.

Don’t Do These 11 Things If You Wear Daily Disposable Contacts!

Countless people around the world wear daily disposable contact lenses or dailies. These popular single-use lenses are removed and discarded at the end of each day, and a new, fresh pair is inserted the next morning. Used properly, dailies promote eye health, and they’re comfortable and convenient.

Despite the many advantages associated with wearing daily disposables, there are plenty of ways you can damage your eyes and vision — some you may never have considered.

1. Don’t Touch Contacts with Dirty Hands

Before touching your lenses, make sure to wash your hands thoroughly with soap and water. By touching your contact lenses with dirty hands, you transfer bacteria to your lenses, which can lead to an infection. Preferably dry your hands with a disposable paper towel rather than a cloth towel, and ensure that no remnants of the towel remain on your fingers.

2. Don’t Expose Your Contacts to Water

Any source of water, whether tap, pool, or lake water, can change the shape of your lenses and cause micro-abrasions on your cornea. Plus, the water may contain bacteria that can wreak havoc on your eye health and cause you to experience temporary vision loss or even permanent blindness.

If you must get in the water with your contacts on, make sure to wear waterproof goggles. If you do get water on your contact lenses, dispose of these lenses and insert a new pair. Exposing contact lenses to chemicals like chlorine binds to the lens and cannot be cleaned off. It then leeches onto the cornea and causes irritation.

The next time you’re tempted to swim or shower with your lenses on, think twice before doing so.

3. Don’t Reuse Your Contacts

Daily disposable contacts are designed to be thrown away after every single use, and people who reuse them risk painful and risky outcomes. Dailies are thinner, more fragile, and don’t hold moisture as well as other contacts.

Users sometimes attempt to increase the lifespan of these lenses by cleaning them in a disinfecting solution and wearing them for several days or even weeks at a time. This is problematic, as the lens material doesn’t allow for repeated disinfecting. In fact, the process of cleaning the lenses tends to be not only ineffective but also breaks down the lens itself, increasing the risk of the lens falling apart while in the eye. The risk of complications and infection is not worth the few saved bucks.

4. Don’t Insert a Dropped Contact In Your Eye

One of the perks of daily lenses is that they are less expensive (per lens) than other types of contacts. So if you find yourself dropping a lens into the sink or on the floor, don’t bother placing it back in your eye. Doing so can cost you your eye health.

5. Don’t Ever Put Contacts In Your Mouth

It seems like a funny concept, doesn’t it? You wouldn’t believe the number of people who do this. If you drop a contact lens, avoid rooting around the floor trying to find it, and if you do, definitely don’t put it in your mouth to lubricate it. Your mouth contains bacteria that can infect your eyes once you reinsert your contacts.

Play it safe by carrying around an emergency pair of glasses or an extra pair of daily disposable contacts in your bag, your car, or at work.

6. Don’t Overwear Your Daily Lenses

Wearing your lenses for long periods of time can damage your eyes, even if they’re daily contacts. The maximum recommended daily use for any contact lens is 14-16 hours, though Dr. Lowy will determine the exact number of hours you should wear your lenses. Your eyes, just like any other part of your body, need to rest. Your corneas receive oxygen from the air, not from blood vessels, and while it’s healthy to wear contacts during the day, wearing them for extended periods can significantly reduce the amount of oxygen your eyes receive, which can lead to complications. If you don’t give your eyes the rest they need, your corneas might get swollen, which can lead to corneal abrasion and even bacterial infection.

7. Don’t Sleep With Your Lenses

Daily lenses should never be worn overnight. You’re risking your sight by sleeping in a lens that’s not approved for overnight use, as it can lead to ocular irritation, swelling and corneal ulcers.

8. Don’t Insert Contacts Before Completing Your Morning Routine

Avoid inserting your contacts before you shower or wash your face, since you risk exposing your lenses to tap water and the bacteria that come with it. We also recommend that you insert your lenses after blow-drying and styling your hair, especially if you’re using hairspray or other aerosols, as these products can dry out your contacts. Additionally, the spray can coat the lenses and leave a film that not only irritates the eyes, but can make it difficult to see. If you’re at the hairdresser’s and cannot remove your lenses, shut your eyes when spray is applied.

9. Don’t Get Makeup On Your Contacts

Insert your contacts before applying makeup, because any makeup residue on your hands, such as mascara, can easily transfer to your lenses.

It’s not uncommon for people to get concealer, eyeliner or mascara on their contact lenses. If that happens, immediately remove the lens and clean the makeup with solution (while making sure to dispose of the lens before bed). Otherwise, simply replace with another lens. Avoid wearing waterproof makeup, since it can’t always be removed from your lenses, even when rinsed with solution.

To prevent makeup from getting on your lenses, don’t apply mascara all the way from the base of your lashes up. Instead, apply it from the midway point. It’s also important not to apply eyeliner on the inner lid of your eye, but rather to the skin above your lashes.

10. Don’t Wear Contact Lenses If Your Eyes Are Irritated

As the saying goes, “if in doubt – take them out!” If your eyes feel irritated, uncomfortable, or if you notice any pain or redness, don’t power through. If your symptoms last a while, contact Dr. Lowy at Lowy & Sewell Eye Care. You don’t want to let a serious infection go unchecked.

When your eyes feel more rested and are free of discomfort, put in a fresh pair of contacts.

11. Don’t Rub Your Eyes

If your eyes feel itchy or dry, or if a lens feels out of place, you may be tempted to rub your eyes. But rubbing, whether with contacts or without, can lead to long-term ocular issues. This may cause you to experience blurred vision, and may even damage your cornea. Instead, Dr. Lowy can recommend eye drops to relieve any discomfort. Make sure to apply them only when contact lenses are removed.

Above, we have delved into things you should never do with daily contact lenses. Fortunately, if you do make a mistake, you can remove the lens and replace it with a fresh one. The few dollars you might save by not opening a new pack aren’t worth the damage a mistake can cause.

 

If you have any questions or are interested in finding out more about contact lenses, contact Lowy & Sewell Eye Care in Concord today. Dr. Lowy will be happy to explain how to care for your eyes and maintain your vision.

Are Floaters and Flashes Dangerous?

You’ve likely experienced occasional visual “floaters” or flashes and may have wondered what they were and if they’re a cause for concern. They look like tiny lines, shapes, shadows, or specks that appear to be drifting in the visual field.

Eye flashes resemble star-like specks or strands of light that either flash or flicker in one’s field of vision. They can either be a single burst in one visual zone, or can be several flashes throughout a wider area. Flashes can sometimes be missed as they most often appear in the side or peripheral vision.

Floaters & Flashes Eye Care in Concord, Ontario

If you suddenly, or with increasing frequency, experience flashes or floaters, call Lowy & Sewell Eye Care and schedule an eye exam with Dr. Lowy right away to rule out any serious eye conditions.

What Causes Floaters?

The vitreous in the eye is a clear gel that fills most of the eyeball and resembles raw egg-white. Within the vitreous are small lumps of protein that drift around and move with the motion of your eyes. When these tiny lumps of protein cast shadows on the retina — the light-sensitive lining at the back of the eye — the shadows appear as floaters.

As we age, the vitreous shrinks, creating more strands of protein. This is why the appearance of floaters may increase with time. Floaters tend to be more prevalent in nearsighted people, and occur more frequently following cataract surgery or an eye injury.

What Causes Flashes?

Flashes result from the retinal nerve cells being moved or tugged on. As the vitreous shrinks over time, it can tug at the retina, causing you to “see stars” or bursts of light. The process of the vitreous separating from the retina is called “posterior vitreous detachment” (PVD) and usually isn’t dangerous.

In about 16% of cases, PVD causes tiny tears in the retina that can lead to retinal detachment — a sight-threatening condition that causes irreversible blindness if left untreated.

Other possible causes of flashes are eye trauma or migraine headaches.

When To Call Your Optometrist About Floaters

If you experience any of the following symptoms, promptly make an appointment with an eye doctor near you for emergency eye care.

Symptoms You Shouldn’t Ignore

  • A sudden onset of floaters accompanied by flashes (which can be any shape or size)
  • An increase of floaters accompanied by a darkening of one side of the visual field
  • Shadows in the peripheral vision
  • Any time flashes are seen

In many cases, seeing floaters is no cause for concern; however the above symptoms could indicate retinal detachment—which, if left untreated, could cause a permanent loss of sight or even blindness.

If the receptionists pick up the phone and hear the main concern is floaters or flashes, they will try to squeeze in the appointment within 24 hours. Expect the pupils to be dilated during your eye exam, so the eye doctor can get a really good look at the peripheral retina to diagnose or rule out a retinal tear or other serious condition, as opposed to a non-vision-threatening condition such as uncomplicated posterior vitreous detachment (quite common) or ocular migraine.

Please contact Lowy & Sewell Eye Care in Concord at 905-738-6680 with any further questions, or to schedule an eye doctor’s appointment.

3 Ways Diabetes Can Affect Your Vision and Eyes

Did you know that people with diabetes are 20 times more likely to get eye diseases than those without it? There are three major eye conditions that diabetics are at risk for developing: cataracts, glaucoma, and diabetic retinopathy. To prevent these sight-threatening diseases, it’s important to control your blood sugar level and have your eyes checked at least once a year by an eye doctor.

But First, What Is Diabetes?

Diabetes is a disease that is associated with high blood glucose levels. Insulin, a hormone produced by the pancreas, helps our cells get energy from the sugars we eat. Diabetes develops when the body doesn’t produce or respond to insulin effectively, leaving too much sugar in the blood stream instead. Over time, diabetes can lead to potentially irreversible ocular damage and poor eyesight. However, by taking care of your blood sugar levels and your eyes, you can prevent vision loss.

Annual eye exams are recommended for everyone, but routine screenings are even more important for diabetics. Eye doctors may send diabetic eye health reports to a patient’s primary care physician or internist to adjust medication as needed to prevent complications.

What’s the Link Between Vision and Diabetes?

Blurred vision or fluctuating eyesight clarity is often one of the first noticeable signs that diabetes has begun to affect your eyes. Sometimes, fluid leaking into the eye causes the lens to swell and change shape. This, in turn, makes it difficult for the eyes to focus, resulting in fuzzy vision. Such symptoms can indicate that an eye disease is developing, or may simply be due to imbalanced blood sugar levels which can be rectified by getting your blood sugar back to healthy levels.

If you start to notice blurry vision, make an appointment with Dr. Lowy as soon as possible.

The 3 Ways Diabetes Impacts Vision

Cataracts

While cataracts are extremely common and a part of the natural aging process, those with diabetes tend to develop cataracts earlier in life. Characterized by a clouding or fogging of the lens within the eye, cataracts impede light from entering the eye, causing blurred vision and glares. The best treatment is cataract surgery, which is very safe and effective.

Glaucoma

Glaucoma refers to a group of eye diseases characterized by optic nerve damage. Since it tends to impact peripheral vision first, glaucoma often goes unnoticed until significant damage has occurred. However, routine glaucoma screenings can detect warning signs; early treatment can prevent disease progression and vision loss.

Although there is no true cure for glaucoma, most glaucoma patients successfully manage it with special eye drops, medication, and on occasion, laser treatment or other surgery. The earlier glaucoma is diagnosed and managed, the better the outcome.

Diabetic Retinopathy

Diabetic retinopathy occurs when the small blood vessels on your retina (capillaries) become weakened and then balloon (microaneurysm) due to poorly controlled blood sugar levels. The resulting poor blood circulation in the back of the eye causes more abnormal blood vessels to grow, which also bleed or leak fluid, and can lead to scar tissue, retinal detachment and even blindness, over time.

Often there are no symptoms until the advanced stages of diabetic retinopathy, where patients may begin to see spots and missing patches in their vision. Retinopathy can be treated through surgery and eye injections, but the best way to prevent this disease from progressing is to regularly have your eyes screened.

The good news is that diabetic eye disease can often be prevented with early detection, proper management of your diabetes and regular diabetic eye exams. Contact Lowy & Sewell Eye Care in Concord to set up your eye doctor’s appointment today.

Visiting Your Optometrist During COVID-19

Is your eye doctor’s appointment coming up? Are you worried about going to the eye clinic during the new coronavirus (COVID-19) pandemic? Rest assured, keeping our patients and staff are safe is our top priority.

We anticipate that this outbreak will continue for a while, and do not want our patients to neglect their eye care needs during this critical time. Our optometric clinic is prudent and has adopted specific measures to protect our patients and staff from potential exposure to COVID-19 during this time of uncertainty.

That said, guidelines for slowing the spread of this epidemic are rapidly changing. Please pay close to attention to local regulatory changes to get the most up-to-date information on whether practices can still remain open/ accept non-emergency cases.

Here Are the Precautions Our Eye Clinic Is Taking to Limit COVID-19:

We employ a strict office policy that mandates that all eye doctors, opticians, office staff, and patients not enter if they are feeling unwell or have a fever, cough, sore throat, runny nose, shortness of breath, or have been exposed to a known case of COVID-19 or traveled outside of the country within the last 14 days.

The staff may ask you to wait outside rather than in the waiting area in order to protect yourself and others from any circulating germs. Furthermore, we are trying to schedule our appointments in such a way that our waiting room remains as empty as possible.

During your eye exam:

  • The eye doctor may use a special plastic barrier called a slit-lamp breath shield to block the exchange of breath between patient and doctor.
  • The optometrist may wear a mask with a plastic shield over the eyes.
  • The practitioner will wait for your slit-lamp eye exam to be over before speaking with you or answering any questions you may have.
  • We sanitize all equipment and patient contact surfaces after every use and at the end of the day.
  • We sanitize all surfaces and equipment (front desk counters, telephones, pens, door handles, waiting room chairs) with antibacterial wipes.
  • All staff members wash their hands after contact with each patient and throughout the day.
  • Our office is equipped with several sanitizing stations.

Coronavirus and Your Eyes – What You Should Know

As coronavirus (COVID-19) spreads around the world, health professionals are demanding that people limit their personal risk of contracting the virus by thoroughly washing their hands, practicing social distancing, and not touching their nose, mouth, or eyes. In fact, it may surprise you to learn that the eyes play an important role in spreading COVID-19.

Coronavirus is transmitted from person to person through droplets that an infected person sneezes or coughs out. These droplets can easily enter your body through the mucous membranes on the face, such as your nose, mouth, and yes — your eyes.

But First, What Is Coronavirus?

Coronavirus, also known as COVID-19, causes mild to severe respiratory illness associated with fever, coughing, and shortness of breath. Symptoms typically appear within 2 weeks of exposure. Those with acute cases of the virus can develop pneumonia and other life-threatening complications.

Here’s what you should know:

Guard Your Eyes Against COVID-19

  • Avoid rubbing your eyes. Although we all engage in this very normal habit, try to fight the urge to touch your eyes. If you absolutely must, first wash your hands with soap and water for at least 20 seconds.
  • Tears carry the virus. Touching tears or a surface where tears have fallen can spread coronavirus. Make sure to wash your hands after touching your eyes and throughout the day as well.
  • Disinfect surfaces. You can catch COVID-19 by touching an object or surface that has the virus on it, such as a door knob, and then touching your eyes.

Coronavirus and Pink Eye

Pink eye, or conjunctivitis, refers to an inflammation of the membrane covering the front of the eyeball. Conjunctivitis is characterized by red, watery, and itchy eyes. Viral conjunctivitis is highly contagious and can be spread by coughing and sneezing, too.

According to a recent study in China, viral conjunctivitis may be a symptom of COVID-19. The study found conjunctival congestion in 9 of the 1,099 patients (0.8%) who were confirmed to have coronavirus.

If you suspect you have pink eye, call your eye doctor in Concord right away. Given the current coronavirus crisis, we ask patients to call prior to presenting themselves at the office of Dr. Lowy, as it will allow the staff to assess your condition and adequately prepare for your visit.

Contact Lenses or Eyeglasses?

Many people who wear contact lenses are thinking about switching to eyeglasses for the time being to lower the threat of being infected with coronavirus.

Wearing glasses may provide an extra layer of protection if someone coughs on you; hopefully that infected droplet will hit the lens and not your eye. However, one must still be cautious, as the virus can reach the eyes from the exposed sides, tops and bottoms around your frames. Unlike specialized safety goggles, glasses are not considered a safe way to prevent coronavirus.

Contact Lenses and COVID-19

If you wear contacts, make sure to properly wash your hands prior to removing or inserting them. Consider ordering a 3 to 6 month supply of contact lenses and solution; some opticals provide home delivery of contact lenses and solutions. At this stage there is no recommendation to wear daily lenses over monthlies.

Don’t switch your contact lens brand or solution, unless approved by your optometrist or optician.

Regularly Disinfect Glasses

Some viruses such as coronavirus, can remain on hard surfaces from several hours to days. This can then be transmitted to the wearer’s fingers and face. People who wear reading glasses for presbyopia should be even more careful, because they usually need to handle their glasses more often throughout the day, and older individuals tend to be more vulnerable to COVID-19 complications. Gently wash the lenses and frames with warm water and soap, and dry your eyeglasses using a microfiber cloth.

Stock up on Eye Medicine

It’s a good idea to stock up on important medications, including eye meds, in order to get by in case you need to be quarantined or if supplies run short. This may not be possible for everyone due to insurance limitations. If you cannot stock up, make sure to request a refill as soon as you’re due and never wait until the last minute to contact your pharmacy.

It is important that you continue to follow your doctor’s instructions for all medications.

Digital Devices and Eyestrain

At times like this, people tend to use digital devices more than usual. Take note of tiredness, sore eyes, blurry vision, double vision or headaches, which are symptoms of computer vision syndrome if they are exacerbated by extensive use of digital devices, and might indicate a need for a new prescription in the near future. This usually isn’t urgent, but if you’re unsure, you can call our eye doctor’s office.

Children and Digital Devices

During this time your children may end up watching TV and using computers, tablets and smartphones more frequently and for more extended periods too. Computer vision syndrome, mentioned above, can affect children as well. We recommend limiting screen time to a maximum of 2 hours per day for children, though it’s understandably difficult to control under the circumstances.

Try to get your child to take a 10 to 15 minute break every hour, and stop all screen time for at least 60 minutes before sleep.

Children and Outdoor Play

Please follow local guidelines and instructions regarding outdoor activities for your children. If possible, it’s actually good for visual development to spend 1-2 hours a day outside.

 

From all of us at Lowy & Sewell Eye Care in Concord, we wish you good health and please stay safe.
