What is the primary characteristic of short sightedness?

Short sightedness, or myopia, primarily manifests as difficulty seeing distant objects clearly. This condition occurs when the eyeball is slightly elongated or the cornea has too much curvature, causing light rays to focus in front of the retina rather than directly on it. As a result, individuals with short sightedness can see nearby objects quite well but struggle to focus on objects that are far away. This characteristic distinguishes it from other visual impairments, such as hyperopia (farsightedness), where the difficulty lies in seeing objects that are close. While the other options describe different visual conditions or states, they do not accurately represent the primary issue associated with short sightedness.
