These include issues around the governance of the therapy, whether treatment should be available only to those who can afford it, and whether the availability of treatment creates a stigma for those with color blindness. Given the large number of people with color blindness, there is also the question of whether color blindness is a disorder. [16]
Gene therapy is a general treatment for genetic disorders; it uses viral vectors to carry typical genes into cells (e.g. cone cells) that are not able to express functional genes (e.g. photopsins). It may be possible to restore color vision by adding missing opsin genes – or a functional copy of the entire gene complex – into
Retinal gene therapy holds a promise in treating different forms of non-inherited and inherited blindness.. In 2008, three independent research groups reported that patients with the rare genetic retinal disease Leber's congenital amaurosis had been successfully treated using gene therapy with adeno-associated virus (AAV).

In this work, they gave gene therapy to two red-green color-blind squirrel monkeys, combined with training. After five months, the monkeys began to be able to distinguish red and green. There is some potential that a similar treatment may be eventually developed for humans. [4] [5] [6] Neitz and coauthors have also proposed that gene therapies ...
There is no cure for most causes of color blindness; however there is ongoing research into gene therapy for some severe conditions causing color blindness. [2] Minor forms of color blindness do not significantly affect daily life and the color blind automatically develop adaptations and coping mechanisms to compensate for the deficiency. [ 2 ]
