How Your Daily Habits Could Be Harming Your Eyes

Using old makeup, forgetting to wear your sunglasses, or even rubbing your eyes could increase your risk of developing an eye injury, disease, or infection. Fortunately, it's easy to avoid many types of eye problems by making a few changes to your usual routine. Your risk of eye issues could be higher if you do any of these things.

Rub Your Eyes

Like most people, you probably rub your eyes without even thinking about it when you're tired or your eyes feel a little uncomfortable. Rubbing your eyes may seem like a harmless habit but can cause several eye issues, including:

  • Corneal Abrasions. These painful scratches develop on the cornea, the clear layer of tissue that covers your iris and pupil. You may be more likely to develop a corneal abrasion if there's a small piece of dust or debris in your eye when you rub it.
  • Dark Circles Under Your Eyes. Vigorous rubbing may break small blood vessels under your eyes, causing the skin to look darker. Rubbing may also cause puffiness and wrinkles.
  • Keratoconus. Keratoconus is a condition that occurs when your cornea thins and becomes cone-shaped. The condition distorts your vision and makes it hard to see clearly. Rubbing your eyes, particularly if you use your knuckles, may raise your risk of keratoconus, according to a French research study that appeared in the February 2020 issue of Cornea.

Touch Your Eyes Without Washing Your Hands

Washing your hands before touching your eyes is an easy way to avoid eye infections caused by bacteria, viruses, dirt, and other substances. Handwashing can also keep you healthier. Many viruses, including influenza, enter the body through the eyes and other mucus membranes.

It's particularly important to wash your hands before you put in or take out your contact lenses. If you handle your lenses with dirty hands, you might develop a severe infection that could cause permanent vision issues.

Leave Your Sunglasses at Home

Wearing sunglasses protects your eyes from the harmful effects of ultraviolet (UV) light year-round. Exposure to UV light increases your risk of cataracts, macular degeneration, cancer, and growths on your eyes. When you shop for sunglasses, read labels before you make your purchase. Sunglasses that offer 100 percent protection from UVA and UVB rays are the best choice.

Don't Wear Safety Glasses

Safety glasses protect your eyes on the job and at home. Wearing the glasses keeps chemicals, and slivers of wood, metal, glass, and other materials from damaging your eyes. Wear the glasses any time you work with dangerous chemicals or use machinery, including saws, sanders, drills, and lawnmowers.

Never Clean Makeup Brushes or Use Old Makeup

Your makeup habits may be the reason you develop a painful eye infection. Protect your vision by:

  • Cleaning Brushes and Applicators at Least Once a Week
  • Disposing of Eye Makeup After Three Months
  • Throwing Out Eye Makeup if You've Had an Eye infection
  • Avoiding Applying Eye Makeup in a Moving Vehicle
  • Not Sharing Eye Makeup

Changing the way you apply eyeliner may also help you keep your eyes healthy. University of Waterloo researchers discovered that eyeliner migrated into the tear film of the eye much more quickly when it was applied to the inner part of the eyelid. Eyeliner can cause redness, discomfort sensitivity, and eye infections if it enters the tear film. The product can also build up on contact lenses, making them feel uncomfortable.

Spend Too Much Time Viewing Digital Screens

Dry eye, eyestrain, blurred vision, and headaches can occur if you don't take breaks from your digital screens periodically. The American Optometric Association recommends following the 20/20/20 rule to improve eye comfort. After viewing a screen for 20 minutes, look at an object 20 feet in the distance for at least 20 seconds.

If you've been working steadily for two or three hours, take a half-hour break that doesn't involve screens of any kind. Adding anti-glare filters and screens to devices and wearing computer glasses that block blue light can also be helpful.

Improving your daily habits and visiting the optometrist for checkups can help you protect your eye health. Has it been a while since you've had an eye exam? Contact our office to schedule your appointment.

Reviews From Our Satisfied Patients

    Dr. Candria Kryko is a wonderful OD. I was seen by Dr. Kryko in Scottsdale recently for an eye exam/contact lens fitting. She is extremely pleasant, attentive, and she took her time to give me a thorough exam and answer all of my questions. Dr. Kryko gave me recommendations on contacts and eye drops, as well, she gave me tips on how I can save on some of my contact expenses. She was professional, attentive, took the time to explain what was needed, and was simply nice to be around. I recommend Dr. Kryko.

    By far the best experience I've had. She took her time to know me, and I received education about my eyesight, and choices I had. The modern technology showed me my options with a prescription and without. The office was on time, professional and inviting. The best for the entire family.

    Dr. Krywko listens and identifies the issues with the eyes! I don’t feel like a number - the time was spent to understand what issues I was having and a comprehensive solution developed! I followed Dr. Krywko from her previous location as she’s THAT good! The team she has surrounded herself with is top notch as well! (Thank you Liz)

    I have worn contact lenses for years but due to my strong near-sighted prescription with high astigmatism could get neither the comfort nor vision very good in standard gas permeable lenses or in soft lenses. I had reverted back to wearing glasses most of the time until Dr. Krywko recommended the SynergEyes lenses. They work great for me and I can finally wear contacts again! Thank you, Dr. Krywko!

    Being new to this state, I can honestly say this is the best eye doctor and I made a good decision coming here. They took the time and patience to help!
