Question

Myopia occurs when the focal point falls _________ the retina. This can be corrected using a _________ lens.

• A. in front of, convex
• B. behind, convex
• C. in front of, concave
• D. behind, concave

Hint:

In myopia, the focal point is in front of the retina, and a concave lens is used to diverge light and correct the vision.

Answer 1

The Correct Option is C

Step 1: Understand Myopia.
Myopia, or nearsightedness, occurs when the focal point of light entering the eye falls in front of the retina. This happens because the eye is too long or the lens is too strong.
Step 2: Corrective lens for myopia.
To correct myopia, a concave lens is used. A concave lens diverges light rays, pushing the focal point back onto the retina.
Step 3: Conclusion.
Thus, the correct answer is (C) in front of, concave.
