CamBlobs Contrast Sensitivity Chart

Newly designed by Dr. John Robson to be an inexpensive alternative for patients to self-monitor their disease progression in between office visits. 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 using a translucent scoring template that is laid over the test sheet to quickly check the results. The test sheet itself then becomes the record for the patient file.
