Question
Read the following statements and choose the correct answer.
I: Assertion: In a myopic eye, the light rays are focused in front of the retina.
II: Reason: The light rays can be focused on 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:
In myopia the near objects can be seen clearly.
The correct answer is: Both I and II are correct, but II is not the correction for I
The correct option is b) Both I and II are correct, but II is not the correction for I.
- Myopia, also called nearsightedness, is a common type of eye defect in which near objects appear clear but distant objects appear blurry. This can be corrected using a concave lens of a suitable focal length.

What is the eye defect shown in the picture below?
The correct option is a)Myopia.
- Nearsightedness or myopia is an eye condition caused by a refractive error that causes distant objects to appear blurry. A nearsighted person can clearly see nearby objects.
- Myopia means that the focus of the eye is in front of the retina instead of on it. The retina is the surface at the back of the eye that collects light.
- It converts light into electrical impulses that the brain interprets as images. Blurry vision can occur when the eye focuses light in front of the retina.
