Custom colorblindness filters?
Has anyone seen or created a custom filter for use by deutans or protans? I'm a deutan and I was strongly considering ordering a pair of Enchroma lenses for computer work. They block the spectrum wavelengths which red-green color deficient cannot distinguish. I thought I might try to make one that blocks these wavelengths, but before I try (because I don't know what I'm doing) I wanted to see if anyone had done this.
Here's a link to the Enchroma patent showing the wavelengths they block:
Any idea where I should start?
