What are the causes of Myopia or Short-sightedness?
Myopia or Short-sightedness is caused due to the elongation of the eye (from front to back), or if the cornea is too powerful for the length of your eye. The light focuses in front of the retina, making distant objects appear blurry.
You can become Short-sighted or Near-sighted at any age, however, in most cases, the condition starts around childhood or early teens. You are more likely to develop it if one or both or your parents are also Short-sighted.
Spending a lot of time focusing your eyes on objects in close proximity to your eyes, such as reading, writing and looking at hand-held devices (phones and tablets) as well as computers can also increase your risk of developing Short-sightedness. Spending time playing outside as a child may help reduce the onset of becoming Short-sighted; the latest evidence1 indicates that higher levels of natural light are beneficial.
