Stereo Optical launches three stereotests including LEA symbols
New tests to screen young children add to extensive product line
Essilor Instruments today announced the launch of three stereotests including LEA Symbols, the Original Stereo Fly, Butterfly, and Randot®, by its Stereo Optical division. Stereo depth perception tests are an effective and easy-to-use method of screening stereoscopic vision for all ages. The three new stereotests including LEA Symbols are designed to screen the vision of young children and supplement the existing extensive Stereo Optical product line.
Lea Hyvarinen, MD, created the LEA Symbols® in 1976. Dr. Hyvarinen designed the circle, square, apple, and house so that each symbol measured visual acuity similarly. Numerous professional associations, including the American Academy of Pediatrics and the American Academy of Ophthalmology, have recommended LEA Symbols as vision screening tests for young children in a policy statement.
