Question

Hypermetropia may arise due to _____:
a. Shrinking of the eyeball.
b. Elongation of eyeball.
c. Long focal length of the eye.
d. Excessive curvature of the eye lens.

• A. b and c
• B. a and c
• C. a and d
• D. b and d

Answer 1

The correct option is B a and c

Hypermetropia is a refractive defect of the eye in which the person is unable to see nearby objects clearly. The near point is farther away from the normal near point (25 cm). This happens because the light rays from a nearby object focus at a point behind the retina. Hypermetropia arises either because the focal length of the eye lens is too long which increases the near point, or the eyeball has become too small which makes it difficult to form the image at the retina.
