Question
Read the following statements and choose the correct answer.
I: Assertion: In a hypermetropic eye, the light rays are focused on the back of the retina.
II: Reason: The light rays can be focused on to the retina by using a convex lens.
- Both I and II are incorrect
- Both I and II are correct, but II is not the correction for I
- None are correct
- Both I and II are correct, and II is the correction for I
Hint:
Also called shortsightedness. Can be corrected with glasses so the image forms on the retina.
The correct answer is: Both I and II are correct, and II is the correction for I
The correct option is d)Both I and II are correct, and II is the correction for I.

- The definition of farsightedness is when the eye is shorter than normal or the cornea is too flat. This means that the light rays are focused behind the retina.
- When a convex lens is used additionally, it converges the light rays into the eyes. Hence, focusing the image on to the retina.
