The Bernell-O-Scope is the classical Brewster type stereoscope for mobile vision screening and vision therapy. Following the socalled "Bioptor" or "Biopter", it can be used to test the most important visual functions, by placing the screening cards on the holder. The test person looks through the ocular. Occluders can be put in front of each eye to test either one eye or both. Unit comes without test cards.

With the screening cards you can test all phorias, the fusion, visual acuity, stereoscopic vision, color vision, most at near and at far. You can also use the tool to perform vision therapy. Trial lenses can be inserted in front of the lenses of the ocular.
