Colorblind Vision Extension
Overview: The Colorblind Filter Extension is a Chrome extension designed to enhance web accessibility for users with color vision deficiencies. It provides a set of colorblindness filters that can be applied to any web page(except chrome tabs like chrome://.......) to simulate how it appears to individuals with various types of color vision impairments. Users can also reset the filters to return to the normal view. None: Removes any applied filters, showing the page in its original color. Grayscale: Converts the page to grayscale, useful for those with certain types of color blindness or for users who prefer a monochromatic view. Protanopia: Applies a filter that simulates protanopia (red-green color blindness), which affects the ability to perceive red hues. Deuteranopia: Applies a filter that simulates deuteranopia (another type of red-green color blindness), affecting green hues. Tritanopia: Applies a filter that simulates tritanopia (blue-yellow color blindness), affecting the perception of blue and yellow hues.
Color Blind Test - Fast & Accurate by BlindnessTest
Quick and accurate color blindness test using Ishihara plates. Identifies deficiencies, works offline, and collects no data. Did you know that 1 in 12 men (8%) and 1 in 200 women (0.5%) have color blindness? Many people go through life without realizing it. Color blindness, also known as color vision deficiency, makes it difficult to distinguish certain colors, which can impact daily life, work, and safety. Whether you struggle with differentiating red and green or confusing blue and yellow, understanding your vision is essential. The Color Blind Test extension provides a quick and accurate way to check your color vision using scientifically validated Ishihara plates, the gold standard for detecting color blindness. With a few clicks, you can determine if you have normal vision, mild color blindness, or a more significant color vision deficiency. This easy-to-use tool is designed for anyone looking for a fast screening test—all within the convenience of their browser. The Color Blind Test extension uses Ishihara plates, a widely accepted method for detecting color vision deficiencies. The test presents a series of color plates, each containing a number or pattern hidden among colored dots. Users are asked to identify the number or shape they see on the screen. Based on their responses, the extension evaluates color perception and classifies vision into different categories. Results are processed instantly without requiring an internet connection. The extension determines whether the user has normal vision, mild color blindness, or a more significant deficiency. The test is optimized for accuracy and convenience, allowing users to assess their vision in just a minute. The test categorizes users into four groups based on their accuracy in identifying numbers on Ishihara plates. 🔴 Strong Color Blind (0-35% accuracy): Users in this category struggle with many colors and may find it difficult to distinguish key color differences. This suggests a severe color vision deficiency, such as Protanopia, Deuteranopia, or strong Tritanopia. 🟥 Red-Green Color Blind (36-45% accuracy): Users in this range have difficulty differentiating red and green shades, the most common form of color blindness. This result suggests Protanopia or Deuteranopia. 🟡 Minor Color Blind (46-75% accuracy): Users in this category experience mild difficulties with some colors, but these challenges do not significantly impact daily life. This result suggests Mild Protanomaly, Deuteranomaly, or Tritanomaly. 🟢 Normal Color Vision (76-100% accuracy): Users with this score can distinguish all colors normally and do not show signs of color blindness. Your score is calculated based on correct answers, incorrect answers, and unsure responses. The final result helps you understand your level of color vision accuracy. 🚀 Key Features – Why Use This Extension? The extension provides an accurate and reliable screening method based on the Ishihara Color Blind Test, a widely used clinical standard. It screens for red-green and blue-yellow color blindness using scientifically validated images. Unlike online tests, this extension works completely offline, so you can take the test anytime, anywhere without needing an internet connection. The simple and intuitive interface makes it easy to use, whether for personal curiosity or as a preliminary screening. This tool is designed for accessibility, making it useful for colorblind individuals, artists, designers, professionals, students, and teachers who rely on accurate color perception. No special equipment is needed. Unlike professional vision tests that require clinical tools, this extension allows users to test their vision directly in their browser with scientifically designed Ishihara plates. This test is helpful for anyone curious about their vision. If you have ever wondered whether you might be colorblind, this quick screening test provides an initial answer. Artists and designers benefit from color vision tests, as working with colors requires accurate perception. Ensuring you can differentiate between subtle color variations is essential for professional work in visual fields. Drivers and pilots need excellent color vision, as traffic signals, dashboard indicators, and navigation instruments often rely on color coding. This test serves as a useful pre-screening tool before official medical vision tests. Parents and teachers can use this tool to identify color vision deficiencies in children early on, ensuring they do not struggle with color-coded learning materials. Medical and science professionals often rely on accurate color perception for analyzing samples, reading test results, and diagnosing conditions. Employers and HR professionals who require color vision screening can also use this extension for quick pre-screening. 🔗 Visit Our Website for a More Accurate Test While this Chrome Extension provides a quick screening test, a more advanced and detailed color vision analysis is available on our website.

It provides a strong indication of potential vision issues, but it is not a medical diagnosis. For an official evaluation, consult an optometrist or ophthalmologist. 💡 Can this test replace a professional diagnosis? ✅ No, this is a screening tool only. If the test indicates color blindness or if you have concerns, visit a professional for a full examination. 💡 Does this extension test for all types of color blindness? ✅ This test primarily detects red-green color blindness (Protanopia and Deuteranopia), which is the most common type. It can also indicate signs of blue-yellow color blindness (Tritanopia), but for a full diagnosis, a professional eye test is recommended. 💡 Can I use this test on different screens or monitors? ✅ Yes, but keep in mind that monitor settings, brightness, and color accuracy may affect results. For the best experience, use a well-calibrated screen with normal brightness and color settings. 💡 Why do I see different results on different attempts? ✅ Variations in lighting, display settings, and how well you focus on the plates can affect results. If your scores vary significantly, try taking the test under consistent lighting conditions for more reliable results. 💡 Is this extension suitable for young children? ✅ Yes, but younger children may struggle to recognize and input numbers accurately. If testing a child, parental guidance is recommended to ensure they understand the task. 💡 Does this extension store or save my test results? ✅ No, the extension does not store or save any test data. Your results are displayed immediately after the test and are not recorded. 💡 Can color blindness develop over time? ✅ Yes, while most color blindness is genetic, certain medical conditions, medications, or eye injuries can lead to acquired color vision deficiencies. If you notice changes in your color perception, consult an eye specialist. 💡 Will this test work on mobile devices? ✅ This extension is designed for desktop use in the Chrome browser.
