Tests

Eye muscle movement test: This test involves testing of muscle strength and its control. In this test the doctor will ask you to visually track a target in different directions in order to observe your eye movements. The object of fixation is usually a pen, between 12 and 16 inches in front of you. The object will be moved up and down and side to side using an “H-shaped” pattern.

Cover test: This test is conducted in order to determine how well your eyes work together. Doctor will ask you to stare at a small target placed at a distance by covering and uncovering each eye to check how much your eyes move.

Pupillary exam: In this kind of test the doctor will have a close watch at the reactions of your pupils to light and objects at close distance. At the same time, the doctor will check the exterior eye, looking at things such as the condition of the white of the eyes and the position of your eyelids.

Visual acuity test: This test is very simple. You’ll be asked to sit in front of an eye chart, with letters that get smaller as you gradually read down each line. You are supposed to cover each eye in turn and, using the other eye, read aloud, going down the chart.

Retinoscopy: The eye doctor may shine a light in your eyes and flip lenses in a machine (phoropter) that you look through while staring at a large target, such as a big “E,” By checking the way light reflects from your eyes, the doctor gets an approximate idea of the lens prescription recommended for you.
