10 Common Eye Myths Dispelled

As a child, my mom would always tell me to turn the light on before reading because reading in dim light would hurt my eyes.  I never really believed this fact so I decided to Google it and see who was right. As it turns out this is a common myth. This gave me an idea to explore other eye myths.

reading in dim light will worsen your visionMyth #1:  Reading in dim light will damage your vision.

Fact:  Dim lighting can make your eyes feel fatigued more quickly, but it will not harm your eyesight.

Doing eye exercises will keep you from needing glassesMyth #2:  Eye exercises can eliminate your need for glasses.

Fact:  Eye exercises do not diminish the need for glasses. Your vision relies on the shape of your eyes and the health of your eye tissues, along with other factors such as genetics.

Fact:  The eyeglasses worn to correct nearsightedness, farsightedness, astigmatism, or presbyopia will not weaken the eyes any more than they will permanently “cure” these kinds of vision problems. Glasses are simply external optical aid that provide vision to people with blurred vision caused by refractive errors.

Fact:  The term “20/20” means a person has excellent central vision. However, other types of vision, such as side vision, night vision, or color vision, might be imperfect. Some potentially blinding eye disease can take years to develop. During this time, they are harming parts of the inner eye, but the central vision can remain unaffected.

Fact:  Sitting to close to a TV will temporarily strain or dry out your eyes, but no permanent damage can be done. Much of the problem can come from the screen, because people staring at them for long periods of time tend not to blink. Some of the strain can be avoided by taking breaks when looking at screens for a long period of time.

MYTH:  Using a nightlight in your child's room will contribute to nearsightednessMyth #6:  Using a nightlight in your child’s room will contribute to nearsightedness.

Fact:  There is not enough evidence to support this claim. Keeping a nightlight on in your baby’s room may actually help them learn to focus and develop important eye coordination skills when they are awake.

Fact:  Eating carrots along with other foods can help to improve your eye health, but that doesn’t mean eating a bunch of carrots alone will improve your eyesight. Carrots contain a lot of Vitamin A, which is an essential vitamin for sight. However, only a small amount is required for good vision.

examMyth #8:  I don’t have any vision problems so I don’t need to see an eye doctor.

Fact:  According to the AAO, “as with all medicine, early diagnosis and treatment can help people with their overall health. Just as with a physical, it makes sense to visit an ophthalmologist (Eye M.D.) for a routine eye exam.” You can view the AAO’s recommended intervals for regular eye exams at

MYTH:  Blind people see only darknessMyth #9:  Blind people see only darkness, nothing else.

Fact:  Only 18 percent of people who are visually impaired are classified as being totally blind and the majority of them can differentiate between light and dark.

cataractMyth #10:  Only older people develop cataracts.

Fact:  “Cataracts are most common among people over 65 years of age; however, cataracts can occur in people who are younger. These cataracts result from conditions such as diabetes, certain medications and other eye problems. In some cases cataracts can be present at birth; these are called congenital cataracts.”
