Answer 2

Answer:

myopia is also known as near sightedness

Explanation:

• myopic person cannot see distant objects clearly because the far point of his/her eye is less than infinity.
• myopia is the defect of the eye due to which the eye is not able to see the distanct object clearly.
• myopia is due to :

a. elongation of the eye ball i.e, the distance between retina and eye lens is increased .

b. decrease in the focal length of the eye lens object is formed infront of the retina and not at the retina itself this defect can be corrected by using a concave lens of suitable power.

c. concave lens of suitable power will bring the image back on to the retina and thus the defect is corrected.
