The condition in which the eye does not refract light equally in all directions is

myopia
hyperopia
astigmatism
presbyopia

The correct answer is: astigmatism

Astigmatism is the condition in which the eye does not refract light equally in all directions. This occurs when the cornea or lens has an irregular shape, causing light rays to focus unevenly on the retina. This can result in distorted or blurred vision at all distances. Myopia (nearsightedness) is when distant objects appear blurry, hyperopia (farsightedness) is when close objects appear blurry, and presbyopia is the difficulty in focusing on close objects that commonly occurs with aging.
