What is the current status of research on color blindness?
Research is currently being conducted on new ways to treat colour blindness and includes research focusing on gene therapies.
Potential gene replacement therapy for red-green colour blindness has been tested on animals.
According to WebMD, scientists have demonstrated that by 'placing certain color-recognizing (photopigment) genes into the cells of male monkeys known to be red-green color-blind allows the animals to tell the difference between the two colors.' They then had the monkey's take a computer-based color vision test to test their vision.
This study suggested that the brain might have the ability to reprogram itself when given new sensory information such as colour recognizing receptors.
