There is currently no treatment for inherited colour blindness. Colour filters or contact lenses can be used in some situations to enhance the brightness between some colours and these are occasionally used in the workplace, but many colour blind people find these actually confuse them further rather than help.
There is hope on the horizon for a ‘cure’ for inherited colour vision deficiency using gene technology – for more information visit www.genevolve.com. This will involve injecting genetic material into the eye so is not for the faint-hearted! At the moment there have been no trials on humans but the process has been proved to work in monkeys.
For acquired colour vision deficiency, once the cause has been established and treated, your vision may return to normal.
