Solution
The correct option is A Myopia
A person with myopia cannot see distant objects distinctly since the far point for that person is nearer than infinity. Such a person may see clearly up to a distance of a few meters. In this condition, the image of a distant object is formed in front of the retina and not on the retina itself. This defect may arise either due to excessive curvature of the eye lens or elongation of the eyeball. A concave lens of suitable power can correct this defect.
