Eye Myth or Eye Fact? What Affects My Vision?

Our vision is such a vital part of our everyday life that it is no surprise that there are countless eye myths that exist about how you can lose your vision. But what if these myths actually contain some truth? How can we differentiate between truth and myth so we can care for our vision correctly? Let’s take a look at some of the more controversial statements about eyesight.

Eyesight Myth or Fact #1

Rubbing your eyes can damage your vision.

Truth. Gently rubbing your eyes occasionally will not do any harm, but rubbing your eyes too often or too hard over a period of time can increase eye pressure. If you have glaucoma, which is characterized by increased eye pressure, rubbing your eyes could cause some damage. You can also tear your cornea by excess rubbing, and there is a thought that you can induce a degenerative condition called keratoconus by too aggressive eye rubbing.

Eyesight Myth or Fact #2

Reading in dim light weakens your eyesight.

Myth. You may give yourself a headache or cause eyestrain when reading in dim lighting, but it is temporary. If you feel pain, burning or fatigue in your eyes, it may be caused by the muscles around the eyes or eyebrow. Any discomfort should go away after a day or so.

Eyesight Myth or Fact #3

Looking at a computer screen affects your vision.

Truth. Although computer screens are not harmful, you increase your risk of being near-sighted when you focus only on close objects. This includes any close-up work and not just computer work. It is thought that the constant contraction of the eye muscles may make the eyeball more elongated, which makes you more short-sighted. When you work on a computer or are doing close-up work, remember the 20-20-20 rule: every 20 minutes, look at something at least 20 feet away for at least 20 seconds.

Eyesight Myth or Fact #4

Kids don’t need to wear sunglasses.

Myth. Sunglasses with UVA and UVB protection are just as important for children as for adults. A great deal of sun exposure happens in childhood, and UV rays can damage the eye cells. Before sending your children outside, apply sunscreen and have them put on those shades!
