Which of the Following is Not a Refraction Disorder

Question

Which of the following is not a refraction disorder?
A) glaucoma
B) myopia
C) hyperopia
D) astigmatism

Accepted Answer

Glaucoma is not a refraction disorder. It is a disease caused by increased pressure within the eye, leading to damage to the optic nerve and vision loss. Myopia (near-sightedness), hyperopia (far-sightedness), and astigmatism are all refraction disorders, which result in distorted or blurry vision due to a problem in the way that light is focused by the eye.
