If a person can clearly see nearby objects but struggles with distant objects, which condition do they have?

• A. Plane mirror
• B. Near-sighted
• C. Far-sighted
• D. Astigmatism

Answer: (B)

Nearsightedness shows up when you can see nearby things clearly but distant ones look blurry. This happens because the eye focuses light in front of the retina, not directly on it. The eye can still bring close objects into focus because the lens can increase its power (accommodation), but distant light rays don’t reach the retina in sharp focus. Clear up close with the eye’s natural focusing, but faraway objects remain blurred. This condition is typically corrected with concave lenses that spread light a little so the focus moves back onto the retina. The other options don’t match this pattern: farsightedness affects near objects more than distant ones; astigmatism causes blurred vision due to irregular cornea curvature, affecting vision at various distances; a plane mirror is not a vision condition, just a reflection device.
