Specialty. This test is done by a trained eye specialist and will take a little longer than the basic exam. It is done by a specialist trained in treating eye problems.
Progressive. In this exam, the doctor reads different colored lights into your eyes for a short period of time. This is usually done as a way to determine the area of the retina affected by the condition.
Matrix. The doctor tests your eyes for depth perception by using a matrix test. You may be asked to make the decision between a black background and a white background, or between two colors.
Functional Examination. This exam will help to rule out any issues with the muscles that control your eyes. Most patients will be required to blink back and forth to allow the muscles to relax.
Functioning Examination. This exam will help to verify that your eyes are functioning normally and can see clearly in both low and high levels of light. The test will usually require the patient to blink into their eyes several times, focusing on various wavelengths of light.
