Low Contrast, Pediatric Opthalmology
Mars Perceptrix Letter Contrast Test Set
The Mars Perceptrix Contrast test is unlike many other Contrast tests that merely assess visual acuity using low Contrast targets, the Mars Perceptrix low Contrast test is a true Contrast sensitivity measure that indicates the lowest Contrasts your patients can perceive, rather than the smallest letters they can identify at some low, arbitrarily chosen Contrast. With the Mars test, it is the Contrast, and not the letter size, which diminishes from the beginning to the end of the chart.
