Optometry Memes

The classic Ishihara color blindness test strikes again! The presenter is showing what appears to be just random dots to the audience, but hidden within those colorful circles is a number that only people with normal color vision can see. Meanwhile, our frustrated teacher knows the truth—his students would be outraged if they could actually read what's written there. Probably something like "Pop quiz today" or "Homework doubled." The beauty of this meme is that approximately 8% of men and 0.5% of women with color blindness are literally experiencing the meme's joke in real-time right now, staring at their screens wondering what everyone else is laughing about.
