Question

3. Myopia can be corrected with the help of
a) Covex lens
b) Concave lens
c) Cylindrical lens
d) All of the above​

Answer 1

Answer:

In a myopic eye, the image of a distant object is formed in front of the retina and not at the retina itself. This defect can be corrected with the help of a concave or diverging lens of suitable power as it will bring the image back on to the retina

Answer 2

Answer:

b) concave lens

Explanation:

Shortsightedness is corrected using a concave (curved inwards) lens which is placed in front of a myopic eye, moving the image back to the retina and making it clearer. Longsightedness is corrected using a convex (outward facing) lens.
