10 ft: SLOAN (13 Line) Chart
10 ft: SLOAN (13 Line) Chart
(9" x 14") Sloan optotype chart for vision testing at 10 feet. Letter size tests a range from 10/80 to 10/5. 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.
