Answer to Question 1

ANS: A
Excessive rubbing of the eyes is a clinical manifestation of visual impairment. Rapid lateral movement of the eyes, delay in speech development, and lack of interest in casual conversation with peers are not associated with visual impairment.

Answer to Question 2

ANS: C
Opacity of the crystalline lens that prevents light rays from entering the eye and refracting on the retina is the definition of a cataract. Myopia, or nearsightedness, refers to the ability to see objects clearly at close range but not at a distance. Amblyopia, or lazy eye, is reduced visual acuity in one eye. Glaucoma is a group of eye diseases characterized by increased intraocular pressure.
