6 Signs You May Need Glasses

Many people don’t realize they have a vision problem. Perhaps they’ve gone years without glasses and haven’t noticed the gradual change in their vision. Or they’ve noticed a change, but put off a visit to an eye doctor. Regardless of whether you’re experiencing problems, make an appointment with Dr. Hwang to maintain your eye health.

There are many clues that your eyesight needs correcting, such as struggling to read up close, or having trouble seeing street signs, or barely deciphering faces while watching a film. If you’re still not sure you need glasses, consider these 6 questions.

Are You Frequently Squinting and/or Experiencing Headaches?

Unless it’s unusually bright, there’s no reason to be squinting if your vision is clear. Although squinting may briefly enhance your eyes’ ability to focus, if done for too long it can tax your eyes and surrounding muscles, which can result in frequent headaches.

If you have to squint while working on your computer or using digital devices, you may be experiencing not only headaches but also digital eye strain or computer vision syndrome. The cure is often a pair of computer glasses, or blue light glasses, which are designed to block out or filter blue light. This can reduce headaches and squinting when using your digital devices.

Are You Struggling to See Up Close?

If the texts on your phone or restaurant menu look blurry, you may be farsighted or presbyopic. While reading glasses are a great option for near tasks, you’ll need to take them off for other activities. Consider getting progressive lenses, which change gradually from point to point on the lens, providing the exact lens power needed for seeing objects clearly at any distance. Progressive lenses help you comfortably see near, far, and in-between all day long.

Do You Struggle to See Things at a Distance?

If you’re having difficulty seeing objects at a distance, you may be myopic (nearsighted). Myopia is the most common cause of impaired vision in children and young adults. Consider a pair of glasses with high-index lenses, which are thinner and lighter than other lenses, along with anti-reflective coating.

Do You Have Blurred Vision at Night?

Are objects or signs more blurry at night? Do you experience halos or glare around lights while driving at night? These may be symptoms of a vision issue, such as myopia — though they can also be attributed to more serious ocular conditions, such as cataracts and glaucoma. To know the cause, get your eyes properly evaluated by Dr. Hwang.

If determined that it is indeed myopia, consider getting prescription glasses with anti-glare or anti-reflective (AR) coating, as they allow more light in and also cut down on glare. This can dramatically improve night vision and help you see more clearly when driving at night.

Are You Experiencing Double Vision?

If you’ve been experiencing double vision, contact Dr. Hwang, who will get to the root of the problem and provide you with a diagnosis. Double vision may be due to an eye misalignment (strabismus), or a corneal irregularity, such as keratoconus, or another medical condition.

If you are seeing double, you may benefit from a pair of glasses with a prism correction that helps correct alignment issues. Special lenses prevent you from seeing double by combining two images into a single one.

However, note that if you experience sudden double vision, it may be a medical emergency that should be checked by an eye doctor immediately.

Are You Losing Your Place or Using Your Finger When Reading?

If you’re frequently losing your spot or skipping lines when reading, you may have a vision problem. This could be due to an eye teaming problem, lazy eye, or astigmatism.

The Importance of Regular Eye Exams

If you’re experiencing any of the symptoms listed above, it is essential to have a highly qualified optometrist examine your eyes to assess your vision and check for any eye diseases — and to do so as soon as possible. This is the only way to determine whether you need glasses or if something else is causing the problem.

Even if you’re not experiencing any symptoms, it’s important to routinely get your eyes checked. Many eye diseases can be effectively treated before you notice major problems, so regular eye exams are important to maintain eye health. Contact Sheridan Optometric Centre in Mississauga to make an appointment with Dr. Hwang. The sooner you get your vision checked, the faster you’ll be able to see clearly and enjoy a higher quality of life.

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 Mississauga right away. Given the current coronavirus crisis, we ask patients to call prior to presenting themselves at the office of Dr. Hwang, 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 Sheridan Optometric Centre in Mississauga, we wish you good health and please stay safe.

How to Keep Glasses from Getting Foggy

Whether you live in a cold climate or have visited one in the winter, you have probably seen someone who just walked in from the cold outdoors sporting glasses that are no longer transparent, or perhaps you’ve experienced it yourself.

Why Do Glasses Fog Up?

There are several factors that cause your glasses to fog up — one of which is ambient heat, in other words, the actual temperature in your surrounding environment. Eyelashes that touch the lens can cause fogging, as well as tight-fitting frames that touch the cheeks (some larger plastic frames can cause this problem), which impede proper airflow. Lastly, high humidity and the sweat and moisture that accompany overexertion/ exercise can also trigger foggy lenses.

Ultimately, glasses cloud over due to moisture in the air condensing on the cold surface of your lenses.

Now that you know the most common reasons why your glasses fog up, it’s time to read about some possible solutions. Below are a few tips to help keep your lenses clear year-round.

4 Tips to Steer Clear of Cloudy Specs

1. Move Your Glasses Further Away from Your Face

Eyeglasses tend to trap moisture and heat, particularly if they are positioned close to your eyes or face, which increases the buildup of fog on your lenses. Consider adjusting the position of your eyewear by pushing your glasses slightly further down your nose. It will stimulate proper air circulation, thereby reducing fog accumulation.

2. Wear Your Seasonal Accessories Wisely

If the weather cools down, try not to wear too many layers, to prevent overheating and producing sweat, which can make your glasses to fog up more. Wear only the necessary amount of clothing to stay warm. If you’re wearing a scarf, consider one with an open weave or a more breathable material to let the air pass through.

3. Avoid Abrupt Temperature Changes

Allow your eyewear to acclimate to changes in temperature. If you are moving from an environment that is cold into one which is warm and humid, try to let your glasses adjust accordingly.

For instance:

As you enter a building, stand in the doorway for a minute or two as the temperature slowly transitions from cool to warm.
When in the car, gradually adjust the heat, particularly when your hands aren’t free to simply remove your glasses and wipe off the fog.

Fogged up glasses are not only irritating but can also be dangerous, especially for those who drive, ski, or operate machinery. So make sure to take the necessary precautions, especially as the weather changes.

4. Swap Glasses for Contact Lenses

If contacts are an option for you, you might want to wear them on those cold days, to avoid foggy glasses syndrome (yeah, that’s a made-up term).

Want to keep your glasses from fogging up? Speak with Dr. Hwang. At Sheridan Optometric Centre in Mississauga, we can advise you about a variety of contact lenses, anti-fog treatment and other solutions to help you see clearly— any day.
