Mars Contrast Sensitivity Test Numbers

Numerals are universally used in cultures all over the world. The Mars Numeral Contrast Sensitivity test version, which functions identically to the Mars Letter Contrast Sensitivity test, is intended for use where patients and clients might be less familiar with the letters of the Western alphabet. The ten numerals in this test are designed with the same geometric principles as the ten Sloan letters, making scores easily compared to those of the Mars Letter version. Hand-held, with quick, simple and convenient scoring. Three chart forms in protective sleeves, user manual and storage case.
