Disclaimer Lucid is not a medical device and is not intended to diagnose, treat, or replace professional medical advice. The color vision screening test is an informal tool based on established color perception research (Ishihara, 1917; Birch, 2012; Brettel et al., 1997) and should not be used as a substitute for a comprehensive eye examination. Always consult a qualified eye care professional before making any decisions about your vision health.

Color Correction Filters Apply scientifically-based daltonization filters that boost contrast and shift colors to help people with red-green or blue-yellow color blindness see more clearly. Works live through your camera.

Color Blindness Simulation See the world the way color blind people do. Lucid simulates protanopia, deuteranopia, tritanopia, and more - perfect for designers and developers testing their work for accessibility.
