Can Cats See In The Dark Better Than Humans
The truth is that cats cannot see in absolute darkness any more than we can.
Can cats see in the dark better than humans. Yes they cannot see in pitch black because the laws of physics dictate it so. As predominantly nocturnal hunters this trait has helped cats for millennia. However they only need one sixth of the amount of light that humans do and can see in very low light. In fact your cat s minimum light detection threshold is about seven times lower than yours.
Cats have large eyes in comparison to the size of their head. They use three clever evolutionary adaptations to allow them to do this. Also there s a downside to seeing better at night. Humans have only four retina rods that are sensitive to light whereas cats have twenty five.
Yet both feline and human eyes require light to form images. Cats won t be able to see in the dark in the rare event that absolutely all light is blocked out but their sight is much more advanced than that of humans for all of their night time adventures. Cats can t see in the dark at least not with their eyes. We all know that cats have better vision than us humans in the dark however they cannot see in total darkness.
First as compared to a human eye the cat eye can let in several times more light. In semi darkness their eyes have evolved to be very efficient with the available light giving them far greater night vision than most animals. All retinas have two types of photoreceptors rods and cones. However they are much better adapted than humans for seeing in low levels of light.
Photons are particles that make up what we know as light. We have established that cats can see very well in the dark but this does not mean that they can see in complete darkness. The reason cats can see better than humans in the dark is because of the way their eyes are made. If there are no photons then no eye however advanced can see anything.
Glare you know cats can see much better in darkness than people can. Their eyes are intelligently designed.
