A) errors of refraction.
B) due to defects within the primary visual cortex.
C) consequences of vitamin A deficiency.
D) types of blindness.

Accepted Answer

Astigmatism, myopia (nearsightedness), and hyperopia (farsightedness) are all types of refractive errors, meaning they result in distorted vision due to a problem with the way the eye refracts light. This is the correct answer. None of them are due to defects within the primary visual cortex, consequences of vitamin A deficiency, or types of blindness.
