Answer 2

Answer:

Myopia or short sightedness is the defect in which person is unable to focus far off objects clearly. This happens as the eye is unable to relax its eye lens enough to form the image on retina and the final image is formed in front of retina. This causes the person to see blurred images of far off objects.

While myopia cannot be cured, it can be treated to slow or even stop it from getting worse. Because myopia typically presents and develops in childhood, these treatments are targeted to children, typically between 6 and 15 years old.
