Hi I found out last week that I am moderately deuteranomalous and protanomalous from my optician.

I know a bit about both of them separately- deutan being green deficiency and protan red deficiency- but does that mean I don’t see any colour with either red or green in it properly?

Jeremy, it’s not that easy to find the correct type of color vision deficiency. Usually you’re not suffering from both at the same time, but there is some mixture of both genetically possible.

Do you know if its possible to be both deuteranomalous and protanomalous? I’ve taken every little test I can get my hands on, and I keep coming to the conclusion that I’m just slightly weak on both. Is this possible? Or can you only be affected by one and not the other?

hi im a redgreen deficient guy, recently heard that tinted eyeglasses help

took the d15 test and was labelled a deutan. re-did the test looking through red cellophane and results much better (almost a ring) but still not normal

what’s your take? thanks
