Humans are creatures of habit, and sometimes those habits are less than ideal for our health. There are many bad habits that can ultimately harm your eyesight if you don’t keep them in check.

Rubbing your eyes

We’re all guilty of rubbing our eyes now and then, especially when spring pollen attacks. And while occasionally rubbing your eyes is pretty harmless, excessive rubbing can lead to multiple problems, some of them serious.

  • Dark circles

Unsightly dark circles are often the result of insufficient sleep, but eye rubbing can make them significantly more noticeable and long-lasting.

  • Red, puffy skin

The skin on and around your eyelids is very thin. Too much rubbing will easily rupture the blood vessels, leaving the areas red and inflamed.

  • Eye damage

Rubbing our eyes is an automatic reaction to feeling something touch them. If dust or other particles enter your eye, rubbing can actually embed the debris deeper into your eye or rake it across the surface of your eye, causing damaging scratches.

  • Infections

Your hands are dirty, no matter how well you wash them. Rubbing your eyes allows dirt and germs from your hands to transfer to your eyes, contributing to eye infections like conjunctivitis. 

  • Keratoconus

Keratoconus is a condition where the surface of the eye loses its shape and begins to bulge, resembling a cone. There is some debate as to whether or not keratoconus is caused by eye rubbing. There is, however, evidence that keratoconus worsens more rapidly with frequent eye rubbing.

If you feel your eyes starting to itch, avoid rubbing them and especially try not to scratch at them. Cool compresses can help relieve itching without damaging your eyes. If itching is a symptom of allergies, treating the underlying cause with medication is your first line of defense.

To avoid itchy eyes, you may also want to consider glasses. Any form of glasses, including sunglasses, make for good defense against allergens or debris entering your eye. Prescriptions sunglasses are a great option for summertime.

Poor diet

We’ve all heard the myth that carrots improve your vision. And while it’s true that no food has the power to actually fix poor eyesight, a healthy diet is vital to maintaining the eyesight you do have. Omega-3 fatty acids and vitamins C and E are essential to keeping your eyes in tip top shape. So try to incorporate leafy greens and oily fish into your diet. Antioxidants are also one way to guard against macular degeneration and other degenerative eye diseases.

If your diet is low in nutrients, your vision can suffer permanent damage. Nutritional blindness is most common in areas where chronic malnutrition or even starvation are prevalent.

Contacts and water

Many people choose contact lenses over prescription eyeglasses because of their convenience or for aesthetic reasons. However, wearing contacts means you have to be extra careful around water. Contact lenses should never be worn in jacuzzis, swimming pools, or the shower. This is because harmful bacteria, viruses and even fungi thrive in water. While these microorganisms are usually harmless to people with a strong immune system, your contacts can trap them between the inside of the lens and the surface of the eye. This lengthens your exposure to these potentially harmful microorganisms and raises your risk of eye infection.

Similarly, you should never rinse or soak your contact lenses in water. Always use the proper cleaning solution.


Smoking is bad for your health overall, but it also specifically affects your eyes. Macular degeneration, a deterioration of the retina which causes blindness, is exacerbated by smoking. The sooner you quit smoking, the lower your odds of developing blindness or severe vision loss.

Too much screen time

You’ve probably noticed that excessive screen time dries your eyes out and makes them hurt. That’s because when we focus on a phone or computer screen, we begin to blink less. Without frequent blinking to spread tears across our eyes, they dry out. You should seek to limit screen time where you can and try to take breaks to rest your eyes. However, if you do need to use a screen, utilizing our Blue495™ Anti-Reflective Lens Coating. This revolutionary technology protects your eyes from harmful blue light that is emitted from computers, smart phones, and other similar electronic devices.

Expired makeup

Did you know makeup expires? Most makeup should be thrown out after a few months, especially anything that uses a brush. Keep your makeup applicators clean and avoid using your hands to apply makeup. Each time your makeup is exposed to the air or to your skin via a brush or applicator, it attracts germs. These germs multiply and can then be spread to your skin and eyes.

Avoid sleeping in makeup. Doing so only increases the likelihood that contaminants will enter your eye.

Skipping eye appointments

Many people avoid the eye doctor unless something is wrong, but annual eye exams are important to your health. An optometrist can spot eye problems before you may notice them, thus improving the prognosis for any treatments. Having an up to date prescription can also ensure you get the most out of your prescription glasses.

As soon as you have an accurate prescription, you can order online glasses from and start seeing clearly for less.
