@bob_ I grew up with a red green colorblind dad and it’s amazing how well people compensate for that colorblindness considering it is the color of traffic lights and so much of the US is green natural surroundings.
I think being aware of my dad’s colorblindness and helping him was unique for me as a daughter, even though obviously I’m not the only child who grew up with a colorblind parent.
Have you tried the corrective glasses?
