A person went for a medical check-up and found that the curvature of his eye lens is increasing. Which of the following defects is he likely to suffer from?

Myopia prevents a person from seeing distant objects clearly because their perception of distance puts it closer to infinity. Such an individual has a clear field of vision out to a few metres. In this circumstance, rather than on the retina itself, the image of a distant object is created in front of the retina. This flaw could develop as a result of severe eye lens curvature or eyeball elongation. A concave lens with the appropriate power can correct this flaw.
