Someone who is colorblind

If you are not suffering from a color vision deficiency it is very hard to imagine how it looks like to be colorblind.

Just play around with it and get a feeling of how it is to have a color vision handicap. As all the calculations are made on your local machine, no images are uploaded to the server. Therefore you can use images as big as you like, there are no restrictions. Red-green color blindness The most common type of color blindness makes it hard to tell the difference b etwe en red and green. There are 4 types of red-green color blindness: Deuteranomaly is the most common type of red-green color blindness.

It makes green look more red. Protanomaly makes red look more green and less bright. Protanopia and deuteranopia both make you unable to tell the difference between red and green at all.

Blue-yellow color blindness This less-common type of color blindness makes it hard to tell the difference between blue and green, and between yellow and red. The human eye contains millions of cone cells which work together to translate light into neural signals that are transmitted along the optic nerve to the brain, resulting in the sensation of color vision.

Instead of seeing green and red as distinct colors, the person sees them as being very similar, thus the resulting color confusion and other frustrations. Color confusion can manifest in many everyday tasks, resulting in frustrating outcomes such as a mismatched outfit, questionable paint choices, incorrect color naming and difficulty interpreting color coded information such as charts, graphs and maps, which may be misconstrued as a learning disorder in early education.

Another task that can be frustrating is driving a car when color blind; for the color blind person, green light tends to look very pale green or nearly white, and red light may seem closer to orange.

Problems also arise when traffic lights are oriented differently than their typical vertical configuration i. If you encounter a driver who hesitates or slows at green lights, consider that they may be a color blind driver looking out for your safety and theirs. The variability of traffic light positions and non-color blind friendly colors pose a unique problem for color blind drivers that can potentially lead to unsafe situations.

Sports is another area where color blindness may inhibit some from playing at their full potential. Take cricket for instance. Because cricket is played with a dark pink ball on green grass, playing cricket with color blindness also spelled "colour blindness" can easily cause confusion and dangerous in-play situations during this fast-moving sport. Recently, an EnChroma customer noticed their year old son struggling with his cricket game:.

The ball is bowled at approx kph from 18m for his grade. As you can imagine, he could only see the ball late, often too late. EnChroma glasses have helped him to see the ball earlier and have given him the confidence to play his shots.

It has been a large improvement. Deutan color blindness is a form of red-green color blindness characterized by the shifting of green light-sensitive cone cells closer to red-sensitive cells than is normal. Protan color blindness is a form of red-green color blindness characterized by the shifting of red light-sensitive cone cells closer to green-sensitive cells than is normal.

Tritan color deficiency is most commonly acquired later in life due to aging of the eye or medical complications. It is characterized by a reduction in the sensitivity of the blue light-sensitive cones such that blue shades seem darker and less vibrant.

In extremely rare cases tritanopia can be inherited also. It is extremely rare, however, those who have achromatopsia only see the world in shades of grey, black and white.
