Comprehensive Eye Examination

These tests range from simple ones, like having you identify letters on an eye chart, to complex tests, such as using digital imaging devices to see and evaluate tiny blood vessels and other structures inside your eyes.A comprehensive eye exam can take an hour or more, depending on the doctor and the number and complexity of tests required to fully evaluate your vision and the health of your eyes.

Visual acuity tests

Among the first tests performed in a comprehensive eye exam are visual acuity tests that measure the sharpness of your eyesight.

Color blindness test

A screening test that checks your color vision often is performed early in a comprehensive eye exam to rule out color blindness.

Cover test

While there are many ways for your eye doctor to check how your eyes work together, the cover test is the simplest and most common. During a cover test, your eye doctor will ask you to focus on a small object across the room and will then cover each of your eyes alternately while you stare at the target. The test is then repeated with you looking at a near object.
