Have you ever wondered how your cat is able to explore distinct environments at night, moving and reaching high spots assertively? This is possible due to his ability to see clearly in the dark. On today’s post, we will talk about how cat vision works in the dark. Check it out:
How does cat vision usually work?
There is a widely spread myth about cats only seeing in black and white. However, this is not true. Even though they are not able to see as many colors as us, they still can distinguish some shadows, such as green, purple, blue and yellow. Furthermore, they do not see very well in long distances and, during daytime, due to exposure to the sun, their pupil size may reduce significantly, which is even more prejudicial to their ability to see what’s standing in front of them.
How does cat vision differ from ours?
To better grasp how cat vision works, some scientists from the University of Pennsylvania’s School of Veterinary Medicine have carried out a study that compares their vision to ours. This study found out that, although the elementary structure of the organ is quite similar to the human, due to genetic factors, the cat’s eye present relevant differences. One of these differences is that the size of their field of view is wider than ours – while their field of view reaches a 200º angle, ours only reaches 180º. Another discrepant factor is their ability to sense moves with acuity and their incomparable panoramic view.
What’s cat vision like in the dark?
The fact that your cat is able to easily move in dark environments does not mean that he is able to see through complete darkness. The major difference is that, in this kind of environment, he is able to see about 50% more clearly than us. This is due to their reflective eye structure which has rod cells (a visual photoreceptor responsible for light reception in the dark). Possibly, you may already have noticed that, in the dark, your cat’s eye emits a green light, doesn’t it? It is precisely this reflective structure that causes that to happen. Another factor that favors your cat’s vision at night is the fact that his pupil is able to expand wider than the human pupil – about 3 times wider, by the way. Because of that, cats have nocturnal habits and are more prone to going hunting at night, since they will find their prey more easily during this period.
