What Makes a Cat's Eyes Shine?

While a cat is looking on sudden light it isdazzlebecause of a temporary blindness, that is the change of colur that we see on cat's eyes that might look green or Yellow or even Rubi

The sudden eerie glow of cat eyes staring you down in the dark can be unnerving, but it's really not that he sees you. You can be sure, that he hear you long before you saw him since he has superior hearing. Cats are born almost blind. The glow of their eyes do not factor into their vision problems any more than brown or green eyes


Even domestic cats are a solitary hunter, Their eyes are specifically designed to help them hunt at night. In order to huntit has a special qualificationsincludes the use of a variety ofvocalizations, as well as afrighteninglookwhile watching the smallest prey moving even from a distance

Cats have excellentnight visionand can see at only one-sixth the light level required for human vision.This is partly the result of cat eyes having atapetum lucidum, which reflects any light that passes through theretinaback into the eye, thereby increasing the eye's sensitivity to dim light.

Watch A REAL boy from China with night-vision ability!

An eye-specialist recently visited the boy, in his home village, in China's Guanxi province, to examine his unusual eyes. the first thing he noticed when he arrived was that Nong's eyes were light blue just like Westerners, but very unusual for Asians. He became even more intrigued when he noticed that when shined upon with a flashlight, the boy's eyes would emit a kind of blue-green light, just like a cat's. As it turned out, his eyes not only looked liked a feline's they also allowed him to see and even read perfectly in total darkness.

What makes a cats eyes shine in the dark?

This is a great question! Also encourages the reader to observe the nature around them and check if cats eyes really shine in the dark.

However your "correct" answer mostly addresses why cats eyes shine, and not how cats eyes shine.

The answer is that some nocturnal animals, like cats, have a reflective membrane that helps conserve light within the eye by reflecting it on the retina before it escapes out of the eye. This gives those animals better vision in the dark

The following site provides an experiment to study this phenomena as a science project: http://www.all-science-fair-projects.com/project1249_78_1.html

Hi ronit

Hi Ronit,

It is realy interesting question,  but I think that the video must be folooed by a scientific background and the 4 options shuld be short.

SEE THE WORLD THROUGH THE EYES OF A CAT
Great Question. Very interesting and exciting question. 
I immediately started to investigate the issue. 
Good built up, nice answers. not so easy.  

There is a direct connection between the question and the answers. The geographic site is perfect, and the video has a direct contribution to the question. 

The information you added by the video of the chines boy is contributing a lot. 

I added a link to an article in Popular Science Magazine called

Thankד

Thank you all for your helpful comments.

I'm sure that now we all know better about night vision of cat's eye (At lease I learn a lot).

I do hope that other students will find it interesting and useful as well
