Correction
According to long sighted person ray of light from close object are focused behind the retina because eyeball is too short
According to short sighted person ray of light from far object are focused infront of retina due to eyeball is too long




Option B is not correct option

Myschool the ans you choose I wrong because for a short sighted person, the eyeball is too long, therefore it makes images to be formed in front of the retina while for a long sighted person the eyeball is too short making images to be formed behind the retina so option D I the correct ans.

B is for shortsightedness and D is for longsightedness

In long sightedness, rays of light of close objects are focused behind the retina which is why a converging/convex Les is used . Therefore the best answer available is D.

Hyperopia (farsightedness) in which distant objects are clear and close up objects appear blurry โ€“ Hyperopia occurs when light rays focus behind the retina (because the eye is either too short or has too little focusing power) and causes near and distant objects to appear blurry.

Dey are right

The correct answer is D โœ…
Explanation (long-sightedness = hypermetropia):
A long-sighted person has difficulty seeing near objects, not distant ones.
This happens because the eyeโ€™s converging power is too weak (or the eyeball is too short).
As a result, light rays tend to focus behind the retina instead of on it.
So:
A โŒ Wrong โ€“ distant objects are usually seen clearly.
B โŒ Wrong โ€“ rays from a close object focus behind, not in front of, the retina.
C โŒ Wrong โ€“ the eyeball is too short, not too long.
D โœ… Correct โ€“ parallel rays of light are focused behind the retina.
๐Ÿ‘‰ Final answer: D
