This Ishihara color blindness test book is the real deal - it's been the gold standard for color vision testing since 1917, and this 2021 edition keeps that legacy going strong! You get 38 of those classic colored dotted plates that optometrists and ophthalmologists have been using for generations. The test works through different designs: some plates only people with normal color vision can see (vanishing design), some show different numbers to colorblind people versus those with normal vision (transformation design), and some even have hidden digits that only colorblind individuals can spot! There's even classification plates that help differentiate between red-blind and green-blind persons. The set comes complete with a user manual that walks you through everything, plus a handy eye occluder so you can test one eye at a time properly. It's all packaged neatly in a box that keeps everything organized and protected. Whether you're a medical professional needing reliable testing tools, an employer screening for color-dependent jobs, or just curious about your own color vision, this test delivers accurate, time-tested results. The plates are crisp and clear, and the whole setup feels professional without being overly complicated. It's pretty amazing that after nearly 100 years, this is still the most widely used color vision test around the world - that really says something about its effectiveness!
