Study of eye test results for visual impairment certificates
Part of Brain & nervous system, Eyes & vision clinical trials.
This study reviews eye exam results from people who are requesting a certificate for visual impairment or blindness. It helps confirm if they meet the World Health Organization's definition of blindness, which may help them get the certification they need.
