We’re back for EleFACT Friday, and today is all about eyes. In the elephant’s retina, there are cones that specifically perceive red hues and others for green. This is referred to as “dichromatic” vision. In human eyes, there are cones for red, blue, and green, making us “trichromatic.” It has been said that color-blind humans share identical sets of visual pigments with elephants, meaning that they can see the colors blue and yellow but reds and greens are not distinguishable.
Elephants are also an Arrhythmic species, which means they can see as well in dim light as they can in the light of day. The retina in the elephant’s eye can adapt and change quickly based on the amount of daylight available. At night, their eyes are most sensitive to blue and violet light, meaning their eyes are fairly well equipped for travel or activity during the darkest hours of the night. However, their range of vision is clear up to only about 10 meters, and they can only see for short distances up to 25 meters.
