this is known hypermetropia. Hypermetropia is also known as far sightedness.
the causes are :
1. this defect arises because of the focal length of the eye lens to long.
2. the eyeball has become too slow.
this can be corrected by using a convex lens of appropriate power.
hope this helps you☺️☺️

which request
in brainly
i lost that acoount this is new i didn't get any request
how can u say the answer clearly as hypermetropia. there is an uncertainity in the question which makes both myopia and hypermetropia are answers.
It is m¥0pi@
Check my comments in the below answer
Also it is not mentioned if he can see beyond 50

answer : (1) Hypermetropia
(2) convex lens
explanation : we know, Hypermetropia (far-sightedness) is a common eye condition where nearby objects appear blurred, but your vision is clearer when looking at things further away.
here, A person is unable to see object distinctly placed within 50cm from his eyes, so the person is suffering from Hypermetropia.
Hypermetropia is caused due to,
decrease in the length of eyeball
increase in focal length of eye lens.
so, this defect can be corrected using convex lens of appropriate focal length.

the answer can be myopia as well as 50 cm distance is far away distance unless otherwise there is a reference for that. In a sense we can say 11 AM as late while taking 8 AM as reference.Meanwhile it can be treated as not late if we take the reference as 10:55 AM.That's why Einstein developed theory of relativity. Everything must have a reference to say about particular thing.
Yeah at 50cm he can see.50cm is a short distance.So going by the information given in the question we can say it is m¥0pi@
And only m¥0pi@ has it
It means n€@® point!!!!!!!!!!!!!
i.e 50 here
