This study is now closed to new participants

(SACRAMENTO, Calif.) — Researchers in the UC Davis Department of Ophthalmology are seeking color-blind males, even those who are mildly color blind, for a study on color vision.

This project is sponsored by Research to Prevent Blindness and is aimed at better understanding human color vision. Specifically, researchers will look at how color filters alter the performance of color-blind males on standard tests of color vision.

Those with color blindness, as a result of their genetic make-up, do not have the fine discrimination of color differences that those with normal color vision have. Researchers want to see if a new type of filter can help color-blind males demonstrate better color discrimination in testing.

Eligible participants need to be male, 18 years or older, free of diabetes and eye disease, and have some form of color blindness.

The principal investigator is John S. Werner, a professor in the Department of Ophthalmology. Testing will take place in the Ophthalmology Department at the UC Davis Medical Center. Eligible participants will be paid $35 for each visit following the initial screening.
