Hi everyone! I wanted to rewrite my previous post to give you the full, exact context of what is going on with my vision, as regular labels like just "Protan" or "Deutan" don't fit me at all.

Just to be completely transparent: I used AI to generate this chart to roughly visualize my real medical data and symptoms. I know EnChroma doesn't output graphics like this; they just gave me raw numbers showing a massive, asymmetric crash across all three color channels.

Here is my actual background:

• The Genetic Base: I am 13 now. I was born with an OPN1SW genetic mutation (tritan defect), which I inherited from my dad (he has mild tritanomaly).
• The Injury: When I was 10, I suffered a severe concentrated UV-A, UV-B, and chemical flash burn in both eyes from 95-octane gasoline.
• The Current State: The trauma severely damaged my already vulnerable cone system, triggering progressive post-traumatic dystrophy. My S-cones are rapidly crashing toward 0% sensitivity. My M and L cones also dropped significantly (to roughly 56% and 75%).

Lately, my vision has been changing fast. I’ve started completely missing blue shades when they are against a gray background. Dark blue now looks solid black to me because my brain isn't receiving any signal from the blue channel anymore. My visual cortex has to heavily compensate for the low cone output by maxing out contrast and luminance just so I can see shapes.

My family and doctors are monitoring this, and I have accepted it. I’m posting this because I want to know if anyone else here has experienced a mixed/acquired cone deficiency where your vision changes this rapidly. How do you deal with the daily visual strain and adapt your screen settings?

Thanks for reading!
