Stereopsis Test:Stereopsis is a test used to measure how well the eyes can work together.
The test involves the patient's ability to judge the depth of an object, or how far away it is.This test is done by using special glasses with prisms that will shift the images seen by each eye.
The patient is asked to look at an image and decide whether it is flat or 3-dimensional.The results of the test can be used to diagnose eye conditions such as strabismus (cross-eyed) or amblyopia (lazy eye).
It can also be used to measure the effectiveness of treatment and the ability of the eyes to work together.
