Contrast Sensitivity Center
|Welcome to the Contrast Sensitivity Test Center
SPARCS is a new generation of vision test that measures contrast sensitivity, a fundamental marker of visual health. SPARCS operates over a web-based testing platform that requires no special hardware or software and permits doctors and patients to monitor visual health in a convenient, economical and clinically validated manner by enabling patients to perform regular at-home tests, and providing doctors with a continuous view of potentially significant changes in patients' test results.
SPARCS is proud to be partnering with Harrow Health and Visionology to bring the potential of vision telehealth into homes and offices around the country and the world.
