Have you heard about the color deficiency correcting sunglasses? The reviews from those they work for are pretty astounding.
I haven't heard of it, but I took their test and had "normal" color vision (which I already knew). Some of the shapes are a challenge to see though, as are the numbers on the full test. It would be interesting to try the tests with the lenses.
Wow! My middle son is color blind. That would be interesting to check out as he gets older and the glasses become cheaper, hopefully.
One of the companies that sells them has an online test you can take to try and determine if they'll work for you, I took it and was deemed "unlikely", my deficiency is pretty bad. But I'd still get a pair because they have 60/30 day money back.
