i can see reds and greens, but very similar shades next to each other, i can't tell. i also can't see either color very well when it's a really small sample size (for example, the green under my power switch on my wireless mouse to show that it's on).

the way i think about it is that people who aren't colorblind have a maximum green value that is much higher than mine. the enchroma glasses, which i've tried, effectively make greens more green. i feel like it makes things inaccurately colored, but exaggerates colors enough to be able to better differentiate. i still can't see past my "maximum green" value though, which is why those marketing videos of people crying are total bullshit. it just looks like a very saturated instagram filter. it doesn't make me see colors i haven't seen before.

i didn't try a color blindness test with them but i should have. the best memory i have of using it is that it was fall time and the leaves on a bush in my yard were turning red, but i had no idea until i put the glasses on, and i could distinctly tell which leaves were turning and which weren't.

i liked them and wanted to keep them, but i couldnt justify the $220 price or whatever it was, so i returned them. i want to get another pair some day
