The correct answer is option 3 - myopia. Myopia, also known as shortsightedness or nearsightedness, is a common eye defect. In myopia, a person has difficulty seeing objects that are far away, but can see nearby objects clearly. This is because the eyeball is slightly elongated, causing the light to focus in front of the retina instead of directly on it. As a result, distant objects appear blurry. Myopia can be corrected with glasses or contact lenses that help to redirect the light onto the retina properly. It can also be corrected through refractive surgery, such as LASIK. The other options listed are different eye defects. Coma is a distortion in the shape of the cornea, hypermetropia is longsightedness, and astigmatism is an irregular curvature of the cornea.
