Question

What is myopia ? Explain with diagram and how is it corrected.

Answer 1

A person with myopia or short sight can see objects close to them clearly, but not far away.

Myopia is caused by the shape of the eye; either the eyeball is slightly too long or the cornea (the clear covering of the front of the eye) is too steeply curved.

Myopia is corrected by spectacles or contact lenses with lenses which are 'minus' or concave in shape. So if you're short sighted, your prescription will have a minus lens power, e.g. -2.50D.


Hope this will help you...... ✌
