10 ft: KCRHN (9 Line) Chart Rx Form each occluder has a Patti(9" x 14") Sloan optotype chart for vision testing at 10 feet. Features two smaller groups 10 25 to 20 8 for repetitive eyesight testing (20 50 to 20 16 equivalent). May be wall mounted or used with illuminated cabinets (66003, 66004, 66016, 66090). The Sloan optotypes were developed on the same basis as Snellen optotypes. Sloan optotypes do not use serifs however, but do use a logarithmic geometric progression.
