		Sight Testing			The Basic Eye Exam
					Your eye care provider takes medical information to begin an examination. During the examination, visual acuity, eye movements and refraction are assessed. A refraction determines the extent of a patient's refrective error (nearsightedness, farsightedness, astigmatism) The results lead to the proper prescription for eyeglasses or contact lenses. The patient's eyes are looking through an instrument called a Phoropter, which resembles a very large pair of binoculars. Lenses with dioptric power are placed before the eyes until the patient sees as clearly as possible. This final combination of lenses determines the patient's prescription.*
