Glasses that Correct Color Blindness
So what is color blindness exactly? Well, in every eye there are things called cones that are sensitive to different color lights. Normally, humans have three different types of cones that are each sensitive to blue, green, or red. However, in certain cases with humans it is possible for some of the rods to have shifted color sensitive or the rods are missing all together, causing dramatic decreases in visual range. For examples, anomalous trichromatism is when there is a shift in the sensitive of one the rods. A common example of this is when the peak sensitivity of the green cones moves toward a higher wavelength, overlapping with the sensitivity of the red cones. This leads to red green colorblindness, where people have a difficulty distinguishing between red and green and many of those colored objects take on a orange tint. A normal human has rods that can see three unique colors. People with anamalous vision, or dicromatic (only two function cone type) vision have a much more l...
