Color blindness powerpoint
Colour blindness is a genetic condition that makes it difficult or impossible to distinguish between certain colours. It is caused by mutations in genes related to colour perception and is more common in males. The symptoms of colour blindness vary between individuals and can range from trouble distinguishing between red and green to seeing only shades of black, white and grey. While there is no cure, colour blindness can be tested for using pseudoisochromatic plates or Ishihara tests, and filters may help some people better distinguish colours. Recent research has shown that gene therapy may one day provide an option to treat colour blindness.
