State two main causes of person developing near sightedness. How can this defect be corrected?
Asked by Topperlearning User | 03 Jun, 2016, 09:30: AM
answered-by-expert Expert Answer

A person develops near sightedness when:

i.The eye lens has very high converging power

ii.The eyeball is too long so that image is not made on the retina but in front of the retina.

Myopia or near sightedness can be corrected by using diverging or concave lens so that the image of the object is formed on the retina.

 

Defective eye: Myopia.

 

Corrected eye
