Knowing the Elements of a comprehensive eye exam.. The American Optometric Association (AOA) recommends that the following tests be performed during a comprehensive eye exam. General Physical Health - A complete health history should be taken to screen for physical conditions and prescription medications that may affect your eyesight. External & Internal Eye Health - Examines exterior and interior of your eyes for signs of possible eye disorders such as cataracts or retinal problems. Current Prescription Check - An evaluation of the prescription in your current eyeglasses. Visual Acuity - Tests your ability to see sharply and clearly at all distances. Refraction - Checks your eye's ability to focus light rays exactly on the retina at distance and near. Tonometry - A test to help detect glaucoma that uses a computer to measure your internal eye pressure. Visual Coordination - A check of eye coordination and muscle control. Focusing Ability - A test of the eyes' ability to change focus. You may also be given special tests for color and depth perception, visual fields, and other vision skills.
