Treatment for color blindness there is currently no cure for color blindness. Women with color blindness with two mutated x chromosomes typically have a carrier mother and color blind father.

It is most commonly inherited from mutations on the x chromosome but the mapping of the human genome has shown there are many causative mutations mutations capable of causing color blindness originate from at least 19 different chromosomes and 56 different genes as shown online at the online mendelian inheritance in man omim. Color blindness is typically an inherited genetic disorder. This makes the test also available for young toddlers and the results can t be influenced by misunderstanding light conditions or any other external factors. Blue yellow color vision defects result from mutations in the opn1sw gene.

A few years ago we posted on research done at the neitz lab at the university of washington that used gene therapy to cure color blindness in monkeys.

Genetic changes involving the opn1lw or opn1mw gene cause red green color vision defects. The most common colors that cannot been seen by a color blind individual are red and green.

Red green colour blindness is passed from mother to son on the 23rd chromosome which is known as the sex chromosome because it also determines sex. Aspects of that research were used to produce. Applying gene therapy to humans in a fda monitored clinical trial is planned.
