Brief summary

The purpose of this research is to validate and determine the accuracy of the experimental device when measuring visual acuity versus our standard visual acuity measurements and to gather voice recordings of letters to help build a special system that recognizes spoken letters.

Interventions

DEVICEFaceScan

Digital visual acuity device built for iOS (iPhone) that conducts an assessment of visual acuity using a combination of integrated light detection and ranging (LiDAR) and voice processing.
