On-screen eye test

Check your eyesight in a couple of minutes. Choose how far from the screen you sit and we calculate the right letter size.

  1. Calibrate the screen with a bank card – you only do this once.
  2. Set the distance from your eyes to the screen, for example 30 cm.
  3. Cover one eye and tap the smallest line you can read. Then do the same with the other eye.

Cover the other eye with your hand. Tap the smallest line you can read.

Calibrate the screen

Hold a bank card against the screen and move the slider until the frame is exactly the size of the card.

Tip: the long side of an A4 sheet is 30 cm. Just for fun – a simple check, not an eye examination.
