Related to ametropia: astigmatism, myopia


An eye abnormality, such as nearsightedness, farsightedness, or astigmatism, resulting from faulty refractive ability of the eye.

[Greek ametros, without measure (a-, without; see a-1 + metron, measure; see meter1) + -opia.]

am′e·trop′ic (-trŏp′ĭk, -trō′pĭk) adj.


(Medicine) loss of ability to focus images on the retina, caused by an imperfection in the refractive function of the eye
[C19: New Latin, from Greek ametros unmeasured (from a-1 + metron measure) + ōps eye]
