[{"data":1,"prerenderedAt":-1},["ShallowReactive",2],{"content-seo:colorBlindness":3},{"description":4,"seo":5,"faq":8},"This free color blind test uses Ishihara-style dot plates drawn fresh in your browser: a number hides among colored dots that match the background in brightness and differ only in hue. Each run shows 8 plates with new random one- or two-digit numbers, so you can't memorize the answers. Type what you see or tap \"I can't see a number\"; 7–8 correct reads as typical color vision, 4–6 as borderline, and 0–3 as worth a closer look. It is a just-for-fun screening, not a diagnosis: screen settings, night mode and lighting all shift the result, and only an eye exam with an optometrist or ophthalmologist can confirm a color vision deficiency.",{"ogTitle":6,"ogDescription":7},"Color Blind Test | Can You See the Hidden Numbers? - Giggleus","🎨 8 Ishihara-style plates with new random numbers every time. Read the hidden digits and get your color vision score in about a minute, just for fun.",[9,12,15,18],{"question":10,"answer":11},"How does this color blind test work?","You read 8 Ishihara-style plates and type the number hidden in each one. The numbers (2–99) are randomly generated every run, and the number and background dots differ in hue rather than brightness.",{"question":13,"answer":14},"What does my color blind test score mean?","7–8 correct suggests typical color vision, 4–6 is borderline, and 0–3 means many numbers stayed hidden. A low score can come from a color vision deficiency, but also from a dim screen, night mode or glare, so retest in good light before reading much into it.",{"question":16,"answer":17},"Can it tell which type of color blindness I have?","No. It gives a single score and does not separate protan, deutan or tritan types or measure severity. That takes an in-person exam with an optometrist or ophthalmologist, for example with printed plates or an anomaloscope.",{"question":19,"answer":20},"How common is color blindness?","Red-green color vision deficiency affects about 8% of men and 0.5% of women of Northern European ancestry, and around 5% of East Asian men. It is usually inherited on the X chromosome, which is why it is far more common in men."]
