corrected by using concave lens
The defect of an eye which is known also known as Near-sightedness is Myopia.
In myopia, the image of the object is formed in front of the retina, rather than on the retina.
How myopia is corrected?
Myopia is corrected by wearing spectacles of concave lens having suitable power. Concave lens is also known as diverging lens.
