iOSfreeglobal

A free vision-check app from the World Health Organization that measures distance and near visual acuity for anyone over eight, using the same principles as a clinical chart test. Its accuracy was evaluated in two research studies. It aims to surface unnoticed vision loss early but does not replace professional eye exams.
