These very stylish and modern-looking clip on anaglyphic (red/blue) glasses offer a functional advantage when used in vision testing and therapy – they do not let in any side light regardless of where the patient moves his or her eyes or head. In this design, no white or ambient light interferes with the testing or therapy routines – each eye receives the maximum, proper color experience.
These clip on Glasses are ideal for diplopia tests, convergence insufficiency disorder testing, heterophoria, and vision therapy routines such as red/green anti-suppression exercises.
The red and blue color lenses have been designed to produce the proper hue and tint that match most Lancaster Red/blue Tests, Hess Screen Test colors, and commonly used vision therapy exercises that require patients to wear red/blue lenses. These lenses are also 100% accurate in the cancellation of Worth 4 Dot tests and Three Character Tests.
