Summer Heat Wave and Your Eyes

This summer, heat waves with scorching temperatures have hit communities nationwide, making an already hot summer even hotter. With high temps and heat waves in certain areas, it’s now more important than ever to protect yourself.

For best practices and tips for maintaining healthy vision in the summer heat, talk to the Saugeen Shores Family Eye Care.

How Can Heat Affect Vision?

Staying out in the sun too long can give you a sunburn and make you feel exhausted. Did you know that it can affect your vision, too?

If you get dehydrated, lack of moisture can make it hard for your eyes to naturally produce enough tears, which can contribute to seasonal dry eye. If you already have dry eye, extremely dry heat can exacerbate your symptoms of itchy, red, sore, and irritated eyes.

Do you sit in front of a fan or air conditioning system? That may feel great, but it can also contribute to dryer and less comfortable eyes.

To give your eyes some temporary relief, keep artificial tears on hand. If your eyes still feel dry or uncomfortable, contact Saugeen Shores Family Eye Care.

Golden sunshine may sound dreamy, but too much isn’t a good thing.

The sun’s ultraviolet (UV) rays can be very harmful, and your eyes are no exception. UV radiation, which can gradually contribute to eye conditions like cataracts and macular degeneration.

Excessive sun exposure can cause headaches, blurry vision, eye pain, and eyestrain. So while you’re out at the pool, hanging out at the beach, sunbathing, or at a backyard barbeque, pay close attention to how much time you’re outside.

If you love the sunshine, you just need to protect yourself. Wear hats, sunscreen, and, of course, 100% UV protective polarized sunglasses. But if you experience discomfort or symptoms that don’t go away on their own, then it’s time to visit your eye doctor.

Computer Vision Syndrome in the Summer

There’s nothing quite like a family road trip or flying to a vacation getaway over the summer. Yet something about being stuck in the backseat of a car or inside of an airplane makes kids feel closed in and restless. It’s then that many kids will play on a smartphone, iPad, or gaming device over many hours to help pass the time.

When it comes to kids and computer use, they’re just as susceptible to the effects of digital eye strain, also called Computer Vision Syndrome, as adults are. In fact, studies show that 25% of children spend more than 3 hours each day on digital devices.

In the summer, when the heat is sizzling, it’s tempting for kids to spend more time than usual watching TV, using a computer, or playing games on their smartphones. To help ease the effects of digital eyestrain, Dr. Larry Carr suggests following the 20-20-20 rule: Every 20 minutes, take 20 seconds to look at something at least 20 feet away. It’s a great way to counteract the effects of Computer Vision Syndrome and let the eyes rest.

This summer, however you choose to beat the heat, don’t forget to protect your vision and keep your eyes strong and healthy. The Saugeen Shores Family Eye Care is always here to help if you have any questions.

Have a great summer!

The Causes and Treatment of Dry Eyes, Dr. Carr – Saugeen Shores Family Eye Care, Port Elgin, ON

This can cause a consistent lack of sufficient lubrication and moisture on the surface of the eye, known as dry eyes.

Normally, the eye constantly lubricates itself with tears by producing them at a slow and steady rate, keeping itself moist and comfortable. Usually these tears consist of three layers, an oily, a watery, and a mucus layer. Each layer has a specific role in lubricating your eyes. The oily layer is outermost. It’s main purpose is to slow evaporation of the tear. The watery layer is in the middle. This makes up the majority of what a person normally thinks of as tears. This layer cleans the eye and helps to wash away small foreign objects and particles. The inner layer consists of mucus. This mucus allows the watery layer to stick to the eye and spread evenly over the eye in order to keep it lubricated. In a person with dry eyes, either hormonal changes, side effects from medication or some other factor causes the eye to either not produce enough tears, or leave out parts of the tear that make proper lubrication possible.

Appointments OJ checkmark

Although dry eyes are not always curable, your optometrist may prescribe artificial tears to help with some of the symptoms. Artificial tears are lubricating eye drops that may help with dry, scratchy feeling eyes. Different artificial tears work in different ways. Some help replenish parts of the tear that your eyes are not producing on its own, others help to produce more tears overall. Your eye doctor will assist you to choose which will help you most.

“Symptoms of dry eyes include stinging or burning in the eyes, scratchiness, and excessive irritation from smoke or wind. Although it may sound counter-intuitive, the eyes’ response to the consistent irritation caused by dry eyes may also cause a person to experience excessive tearing. In this case, the eye is attempting to flush and lubricate itself by producing more tears, but is unable to do so successfully due to the rate of evaporation or inability to spread the tears properly.”, , Port Elgin eye doctor.





Some cases of dry eyes are seasonal, such as those which occur as a result of cold, dry winter air. In this case, your eye doctor may recommend wearing sunglasses or goggles when outdoors to reduce your eyes’ exposure to the sun, wind and dust. For indoors, your optometrist may recommend an air cleaner and humidifier to take dust out of the air and add moisture to air which is too dry.

“These artificial tears should not be confused with eye drops that are advertised to ‘get the red out.’ These eye drops may indeed reduce the appearance of redness in your eyes, but this is accomplished by making the blood vessels in your eyes smaller rather than actually lubricating your eyes. As such, these drops can sometimes actually make your symptoms worse. One should also be aware that if you wear contacts, some eye drops require you to take them out before using the drops and wait 15 minutes or more before reinserting your contact lenses.”

Studies have also shown that nutrition may have a part in helping to relieve some symptoms of dry eyes. Your eye doctor may recommend nutritional supplements such as omega-3. Good sources of omega-3 fatty acids are cold-water fish, cod, herring and salmon, as well as flaxseed oil. Mild dehydration can make symptoms worse too, so be sure to drink plenty of water, 100 percent fruit and vegetable juices and milk.
