Color Blind

[Robert Wagner]

Hello,
I have a patient who is very Red-Green color blind, my question is can you make a Chemistrie with the
density of the old fashion X-chrome (pmma) hard lens color?
In fact he can only see 2 plates on the Ishihara's 24 plate test book.

Robert, Unfortunately we do not sell the red or green lenses for our Chemistrie system. You could potentially fabricate a pair if you can find these lenses in a material thin and flexible enough to snap in our grooved magnets (or you could send us the lenses and we could do them in our lab). We have not done jobs like this out of our lab, but if we had a lens that was the correct thickness for the magnets and bridges, we could probably make it work. I am not sure of the material used for "slip-in" type lenses or if ready made glasses sold by catalogs like Bernell could be edged down to work.

Thank you Joe Z. for your quick response. I will see what I can come up with, if anyone else has an idea I would love to hear it.

Thanks again,
