Isometropia is defined as equal refractive error in both eyes. True or false?

Explanation:
Isometropia means both eyes share the same refractive error, so there is no anisometropia. This can be equal myopia, equal hyperopia, or equal emmetropia in both eyes. The statement is true because the defining idea is equality of refractive error between the eyes, not that the error must be zero. If the refractive errors differ between eyes, that is anisometropia, which can lead to binocular vision issues like suppression or amblyopia in kids.
