Summary

This study will test a new iPhone app called FaceScan that uses LiDAR and voice recognition to measure visual acuity. Researchers at Mayo Clinic will compare the app's results to standard eye exams in 150 adult patients. The goal is to see if the app is accurate enough for home or clinic use, and to collect voice samples to improve the system.
