How do EnChroma glasses help with color blindness?
EnChroma glasses use patented technology to improve color perception in people with red-green color blindness. Developed nearly two decades ago, this technology combines color perception neuroscience, optical dyes, lens material innovations, and advanced manufacturing techniques. EnChroma lenses selectively filter light to increase the contrast between red and green color signals, compensating for excessive overlap in the cone cells responsible for color vision. This helps alleviate the symptoms of red-green color blindness, providing a richer and more colorful visual experience. Approximately 80% of people with this type of color blindness experience an improvement in their ability to distinguish colors.
What is normal color vision?
When light enters the eye, it activates millions of cone photoreceptor cells that can normally detect all the colors of the rainbow. The three types of cone cells, which send signals to the brain, are sensitive to different parts of the visible color spectrum and are generally called blue, green, and red cones.
