Prism
testing
Prisms bend light, changing the object’s position. Because of this property, they are commonly used to detect and measure strabismus (turned or crossed eye). While the patient is staring at an object, prisms of increasing strength are placed over the turned eye until it is aligned with the fellow eye. The stronger the prism that is required to align the eyes, the greater the eye turn.
