Question

which term means \farsightedness; light rays focus behind the back of the eye resulting in loss of distance visual acuity\?
exotropia
photophobia
hyperopia
presbyopia

Explanation:

• Exotropia: It is a form of strabismus where one eye turns outward. It is not related to light rays focusing behind the eye.
• Photophobia: This is an abnormal sensitivity to light. It has nothing to do with the refractive error described.
• Hyperopia (Farsightedness): In hyperopia, light rays focus behind the retina (back of the eye). This causes difficulty in seeing nearby objects clearly (loss of near - visual acuity, but in some cases, it can also affect distance vision depending on the degree of hyperopia).
• Presbyopia: It is an age - related condition where the eye loses its ability to focus on near objects. It is due to the hardening of the lens, not light rays focusing behind the eye.

Answer:

C. hyperopia
