The SpotChecks™ (formally known as CamBlobs™) Contrast Sensitivity Chart was newly designed by Dr. John Robson to be an inexpensive alternative for patients to self-monitor their disease progression in between office visits and is acceptable to various patient populations. Previous to SpotChecks™, commercially available CS tests were expensive, not easily portable or require supervised testing conditions.
SpotChecks™ changes everything about gathering precise contrast sensitivity testing results. Each test is a single use test where patients test themselves by marking an “x” on each contrast target they see. Testing is intuitive; it only takes 2-3 minutes to complete the test and scoring the results is very easy and takes only a minute. The test sheet itself then becomes the record for the patient file.
Quick. Easy. Accurate. Repeatable. Affordable.
