Solution

The correct option is A
Light rays from a closeby object are focused at a point beyond the retina.

In hypermetropia, light rays from a closeby object are focused at a point beyond the retina. Therefore, a focused image is not formed at retina causing a blurred vision of nearby objects.

Q. For a myopic (short-sighted) eye, rays from far distant objects are brought to focus at a point:

FOCUS :focus also called an image point, is the point where light rays originating from a point on the object converge..

BUT, when the object is kept beyond the centre of curvature then rays converge between centre of curvature and the point focus. So now that point CAN BE called as the FOCUS.
