Amblyopia, or lazy eye, is reduced visual acuity in one eye. Amblyopia is usually caused by one eye not receiving sufficient stimulation. The resulting poor vision in the affected eye can be avoided with the treatment of the primary visual defect such as strabismus. Myopia, or nearsightedness, refers to the ability to see objects clearly at close range but not a distance. Hyperopia, or farsightedness, is the ability to see objects at a distance but not at close range. Astigmatism is unequal curvatures in refractive apparatus.
