For People With Color Vision Deficiency
Do Cats See Color? It once was believed cats were color-blind, but they actually can tell the difference between certain colors. However, In nature, color is not particularly necessary to a cat’s survival success.Basically, they see the world around them as shades of blue and green. But though they see color, cats don’t pay much attention to it.
Why Do Cats’ Eyes Glow In The Dark? (always wondered this myself, so creeepy!) Cat’s glow-in-the-dark eyes seem eerie, mystical, even scary when they pop out at you from the black of night, especially since your cat is one of only a few animals that can return a human’s stare. There is a simple explanation for that characteristic green or gold shine. A membrane, called tapetum lucidum, coats the eye and reflects light. When a cat is in the dark, its pupils open wide and light is reflected off them, but they’re not actually “glowing.” This ability along with their extraordinary sensitivity to ultraviolet rays, enables them to see well in the dark.
Can Cats Really See In The Dark? They can’t see in total darkness and their daytime vision is only fair. But they can see better than most humans in semi-darkness. They also can distinguish brightness seven times better than we can. (hint, hint, you can’t see color at night anyway, so that is a factor in why cats don’t pay attention to color as stated above) As nocturnal hunters, their eyes are able to scoop up even the smallest scrap of available light. Their vision generally is blurred at the edges and they see best at six to twenty feet. When it comes to movement, though, a cat doesn’t miss a twitch. By the way, feeding dog food to your cat is a no-no. Dog food lacks taurine, a substance crucial for your cat’s eyesight. A diet without it will make your cat go blind.
