This free app is for medics who ever found themselves at the bedside or in the clinic looking for a Snellen chart.

The optotype size is configured to measure visual acuity at a distance of 4 feet.

The app can display one highlighted letter at a time or the whole chart at once.

Control the displayed letter with finger swipes or pressing screen buttons.

Both imperial and metric units shown.
