Standardized Visual Acuity and Contrast Testing

The Good-Lite ESC2000™ Illuminated ETDRS Clinical Trial Cabinet provides consistent LED retro-illumination for high- and low-contrast logMAR visual acuity testing in clinical eye care, vision research, and clinical trials.

When used with compatible charts, the cabinet supports best-corrected visual acuity (BCVA) assessment and low-contrast visual acuity (LCVA) testing. It accommodates compatible ETDRS, LEA SYMBOLS®, LEA NUMBERS®, Landolt C, Tumbling E, and other visual acuity charts.

LED Illumination

Energy-efficient LED technology provides consistent luminance without the warm-up, burn-in, or routine bulb replacement associated with fluorescent cabinets. The slim 3-inch cabinet depth offers a space-efficient solution for clinical environments.
