http://englishrussia.com/?p=2662#more-2662 I'm not sure about the rest of them, but I CAN'T SEE #5!! haha
Lol, I saw this, went "I can't see 5" saw the reason and went, "OHHH THAT'S WHY!" and recognized the joke immediately afterwards xD.
Took me awhile i stared at number 5 and was like hmmmmmmm so why cant i see it then i read it and was like "OH NO IM GAY!!!!!!" lol duh
I think it's just a color blindness test. If diagnosing people with schizophrenia was as easy as pointing them at circle #6 and asking them to read it, psychiatrists would probably cost a lot less. =P So, no, I don't think you're supposed to see anything in number 5.
All this is is a standard short web-test for color-blindness. If you can't see certain numbers, then you might have some minor form of color blindness. For what it's worth, I can't see number 5 either...
Obviously it's a "joke" to make you think "ZOMG I'm gay". Which for here is news to no one. When I was having a medical done for a workplace they gave me a colourblind test as part of it. I was going along just fine, then got to a card like this and was like "Uh.... I don't see anything" Apparently that was fine. No I'm not colourblind. I think the way SOME of the cards work is that it actually reveals something that is visible to colourblind folks. As an example colourblind people are actually better able to pick out camouflage than "normal" people. Here's a colourblind simulator that lets you upload an image and see how people with different colourblindnesses might perceive it. http://www.colblindor.com/coblis-color-blindness-simulator/ I couldn't get any of them to resolve #5, though after looking at it at different sizes I'm trying to convince myself there's a "14" or "74" in there. Clearly if it were this easy to determine homosexuality someone would have figured it out by now. In other news 10% of the male population is affected by some form of colourblindness
