NUS researchers design free app for early detection of colour blindness
NUS researchers design free game to help detect condition early
Parents will soon be able to tell within minutes if their young children are colour blind, with a simple game available as a free app from next month.
Designed by National University of Singapore (NUS) researchers for children between the ages of three and six, the game requires them to "catch" butterflies of matching colours by tapping a screen.
Those who are colour blind would consistently select different butterflies since they are unable to tell the difference between red and green, for instance.
A study on 32 children by the Singapore National Eye Centre this year found that the game, believed to be a world first, was as effective as existing tests in identifying red-green colour blindness, the most common variant.
EARLY DETECTION HELPS
If a child has colour blindness, it's good to know early. It may have an impact - not just on their visual function - but also emotionally and mentally, like how they cope in school.
