Key Features
Usage:
For use at a distance of 100 cm (1 meter).
Included:
Two charts that can be wall or easel mounted, along with score sheets.
Illumination:
85 cd/m², which is essential for achieving good results.
Letter Sequence:
The sequences are organized into groups of three (triplets), with two triplets per line. Within each triplet, all letters have the same contrast. The contrast decreases from one triplet to the next, even within the same line.
Contrast Sensitivity Testing:
Regular testing of contrast sensitivity is vital for detecting early signs of conditions such as Parkinson’s, Glaucoma, and Cataracts. By using several different contrast levels together, the patient’s contrast sensitivity can be more accurately assessed, and records will be more precise
