Answer to Question 1

ANS: C
A cataract refers to opacity of the crystalline lens that prevents light rays from entering the eye and refracting on the retina. 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.

Answer to Question 2

ANS: B
Cochlear implants are surgically implanted, and they provide a sensation of hearing for individuals who have severe or profound hearing loss of sensorineural origin. Hearing aids are external devices for enhancing hearing. An auditory implant does not exist. An amplification device is an external device for enhancing hearing.
