Researchers in the UC Davis Department of Ophthalmology are seeking males for a study of color vision and aging.

The project is part of a large, multi-year study sponsored by the National Institute on Aging that is investigating age-related changes in normal vision. UC Davis researchers are seeking males between the ages of 16-30 and 55-85 who have some form of color blindness. The UC Davis study will analyze the aging of the photoreceptors in the retina. Photoreceptors absorb light and initiate color perception. In particular, the researchers will attempt to find out if aging is associated with a loss of visual pigments, which are found in the photoreceptors.

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

To schedule a free color vision examination or find out more about the study, contact Holger Knau at (916) 734-4540.
