Projector-mounted vision testing slides are well-established ophthalmological and optometric diagnostic tools that are indispensable to the modern vision testing professional. All Stereo Optical vision testing slides are printed on a piece of high-quality clear photographic film, which is then sealed between two sheets of optically-clear glass to guarantee consistently high optotypes and ensure the integrity of each test.


Cleaning: For vectograms, projector slides, and screening cards, clean and disinfect the surface area gently with disinfectant wipes or a soft, slightly damp, and lint-free cloth with 70% isopropyl alcohol. Never spray alcohol directly on the surfaces.
