What causes myopia?

Myopia occurs if the eyeball is too long or the cornea (the clear front cover of the eye) is too curved. As a result, the light entering the eye isn’t focused correctly, and distant objects look blurred. Myopia affects nearly 30% of the U.S. population.

How can we correct hypermetropia?

Answer: A person with hypermetropia/hyperopia or long sight can see clearly objects far away from them, but not close to them. This is caused by the shape of the eye – the eyeball is slightly too short. It is corrected by spectacles or contact lenses with lenses which are ‘plus’ or convex in shape.
