Seeing and hearing challenges
These challenges use colour, fine detail and quiet sounds. They are games that show how you do on your own screen and headphones.
Screens and headphones are not calibrated, so these activities cannot diagnose colour blindness, measure visual acuity or give a hearing level. See an eye care or hearing professional for that.
