This configuration allows for testing vision under several different luminance levels with optional charts in high contrast, low contrast and threshold contrast and different test distances.

The trans-illuminated versions are identical to the original “Gold Standard” Pelli-Robson Contrast Sensitivity Charts. These charts cover ¾ of the original contrast range and are manufactured to the same true log steps and use the same letters and letter sizes as the originals.

Contrast sensitivity test comparable to the Small Letter Contrast Test.
Detects subtle effects of defocus, low luminance and glare.

Only standardized format accepted in studies sponsored by the National Eye Institute.
Designed for use in clinical studies and low vision evaluations where accurate, repeatable visual acuity measurements are required.
