Answer:
Myopia:- Myopia is the inability to see things clearly unless they're relatively close to your eyes. Also called nearsightedness or shortsightedness, myopia is the most common refractive error among children and young adults.
Causes of Myopia:- Myopia, or short-sightedness, occurs when the eyeball is too long so it affects how the cornea and lens focus. This means objects in the distance appear blurry because light rays are focusing at the front of the retina rather than directly on its surface.
