Ifa person has difficulty in seeing distant objects clearly, what condition is he suffering from and how can it becorrected?

Correct option is A

The correct answer is (a) Myopia, using concave lens.
· Myopia, or nearsightedness, is a common vision condition where distant objects appear blurry while close objects can be seen clearly.
· This occurs when the eyeball is too long or the cornea is too curved, causing light rays to focus at a point in front of the retina rather than directly on its surface.
· Myopia can be corrected using concave (diverging) lenses, which help to spread out the light rays before they reach the eye, allowing them to focus on the retina properly.
Information Booster:
· Myopia, using convex lens: This is incorrect. Convex lenses are used to correct hypermetropia, not myopia.
· Hypermetropia, using convex lens: Hypermetropia, or farsightedness, is a condition where distant objects can be seen clearly, but close objects appear blurry. It is corrected using convex (converging) lenses.
· Hypermetropia, using concave lens: This is incorrect. Concave lenses are used to correct myopia, not hypermetropia.
