Kazunori Asada created Chromatic Glass, an app which makes colors that some people have trouble seeing show up better.
Asada's Brighter and Bigger app, which uses a smart phone for magnification, doesn't seem to be well known in English, but it's available in English. A fast check turned up other magnifying apps, and I don't know whether his is better. This review doesn't mention any apps which have magnification for distant objects, which is something Asada's app does. Asada's app also has optimization for different vision diseases.
A while ago, I noticed that Japanese color printing was unusually good, and wondered whether color blindness was less common there. It turns out that it is, but the difference is 1 in 20 Japanese men have color-blindness vs. 1 in 12 Americans men, which doesn't seem like enough to affect a culture.
The video has a world-wide map of color-blindness prevalence (doesn't specify type) at 2:52. It's color-coded.
Asada wrote the piece about van Gogh possibly being color blind.
