What characterizes nearsightedness (myopia)?

• A. Close objects are seen clearly but distant objects appear blurry because images form in front of retina. Concave lens fix the issue
• B. Far objects are clearer than near objects; convex lens fix
• C. It occurs due to color deficiency
• D. It is corrected with bifocals in all cases

Answer: (A)

In myopia, the eye’s optical system causes the image to form in front of the retina, so distant objects appear blurry while nearby objects can be seen clearly. This happens because the focal point is too close to the lens system (often due to a longer eyeball or a cornea that’s too curved). The practical fix is a concave (diverging) lens, which spreads incoming light slightly so the focal point moves back onto the retina, restoring clear distance vision.

The other statements don’t fit because they describe different situations. Saying far objects are clearer than near objects aligns with farsightedness, which is corrected with convex lenses. Color deficiency relates to how we perceive colors, not how the eye focuses images. And saying bifocals are used in all cases isn’t accurate; many myopia cases are corrected with single-vision lenses, with bifocals or multifocals used only when additional near-vision needs exist or in specific situations.
