Sloan Letter Eye Charts

Sloan letter eye charts use a standardized set of ten optotypes—C, D, H, K, N, O, R, S, V, and Z—engineered to be equally legible so that acuity results stay consistent from one exam to the next. That reliability is why Sloan charts are the design behind many clinical and screening standards, and why practices choosing them care most about accurate calibration, durability, and clean, matte-finished letters that won't glare under exam-room lighting.

This collection brings together wall-mount Sloan charts for optometry offices, pediatric clinics, occupational health screening, and school nurse stations. The McKesson Eye Test Chart (63-3050) offers an 11 x 22 inch matte plastic panel made without natural rubber latex—a practical choice for facilities with latex-sensitivity protocols. The Prestige Medical Eye Chart (3909) in a compact 10 x 18 inch format suits smaller exam spaces, while the Dukal Tech-Med Chart (TM3050) delivers a durable matte-finish plastic panel built for daily use. For a lighter, translucent option, the Graham Field 9 x 14 inch chart (1264) works well where wall space is limited.
