Calibration

Calibrate your device's screen size and anaglyph glasses so Eyeli's tests measure deviation and dissociation accurately.

⚠

Warning

Calibration aligns Eyeli with your device's screen size and colour output, and with the red-green lenses of your anaglyph glasses. Complete both steps below before running any test.

Screen size calibration

Choose a reference object - a credit card or a ruler - that Eyeli can use to calibrate the size of on-screen targets.

Choose Credit Card or Ruler as your reference object.
Place the object on the target displayed on screen.
Use the + / − controls to adjust the on-screen target until it matches your object exactly.
Click Save Calibration.

Anaglyph glasses calibration

This step configures suitable colours for your red-green (anaglyph) glasses and screen, so binocular tests display correctly.

Put your anaglyph glasses on, then click Start.
Right eye: close your left eye and select the circle that appears lightest. You will complete 5 slides for the right eye.
Left eye: close your right eye and select the circle that appears lightest. You will complete 5 slides for the left eye.
Click Finish once complete.

Tip

If two or more circles appear equally light, this is not a problem - select any of them, as both options will work correctly with your glasses.
