Try a dichoptic red/cyan exercise

A simple demo of two-eye training. Wear red/cyan (anaglyph) glasses over your normal glasses.

Before you play: This is a wellness demo, not a medical treatment or test. Individual results vary. Eyeletics is a wellness and training program, not a medical device, and does not diagnose or treat any disease. Stop immediately if you notice double vision, eye strain, headache, dizziness or discomfort, and contact your eye doctor. Not for children or people with photosensitive epilepsy. Take breaks.

Move the bar with your mouse, finger, or ← → keys. Catch the falling blocks.

Settings





Falling blocks are shown at full contrast to your weaker eye; the catcher bar is shown to your stronger eye at the contrast above. Lower it as the game gets easy.
