    I have a friend who saw one of these and said “ah that’s one of those joke pictures where everyone says they can see a word even when there’s no word.” and that’s when he found out he was colour blind.

    Ah ye, I remember being 12 or something, in the early days of the Internet, and my father downloaded one of these and called me to tell him whether the number was a 3 or a 4 (or some shit like that) and I was like…What number? The day we found out I’m colorblind :)

      A surprising number of people don’t find out till they get a health checkup for work somewhere in their 20’s or 30’s. Some chemical exposure can slowly cause colourblindness, especially solvents and heavy metals, so people get checked for it, and plenty find out they’ve apparently always been colorblind.
