Which one among the following is correct for a person suffering from myopia ?
Explanation
Myopia, commonly referred to as near-sightedness or short-sightedness, is a refractive error of the eye. A person with myopia can see near objects clearly, but distant objects appear blurred. This makes Option A the correct statement.
In a myopic eye, the image of a distant object is formed in front of the retina rather than directly on it. This defect arises due to two primary reasons:
- Excessive curvature of the eye lens.
- Elongation of the eyeball.
The far point for a myopic eye is closer than infinity. This vision defect can be corrected by using a concave (diverging) lens of appropriate power, which diverges the incoming light rays so that the image is focused precisely on the retina. Conversely, the inability to see near objects clearly is called Hypermetropia (far-sightedness).
