The first glasses to help people with colour blindness were created by James Clerk Maxwell in 1854. The idea of using contact lenses to correct colour vision is also not new, but previous lenses, such as the Chromagen lenses, are not as effective as the glasses.
‘For the colour vision deficient, the spectacle lenses are the most helpful, being darker tints, but the contact lenses are relatively undetectable,’ says Stephen Dain, an emeritus professor specialising in optometry and the science of vision at the University of New South Wales, who wasn’t involved in this study.
