I question the validity of this product’s claims. In the absence of any appropriately rigorous tests, and in particular double-blind studies, I am profoundly suspicious that this is nothing more than an expensive pair of sunglasses. The technique that they are using might work, but I suspect strongly it depends on the degree to which the individual is capable of registering the colours in question.
I would want to see a lot more science around this before sinking hundreds of dollars on a pair.
