Tapetum Lucidium
Many of you will have pets whose eyes appear to glow in the dark. This ‘Eyeshine’ is caused by the tapetum lucidum (the latin for “bright tapestry”). It’s a layer of tissue found behind the retina of the eye in many vertebrates. It reflects visible light back onto the retina, giving these animals far superior night vision. In this image you can see the back of a horse’s eyeball, along with the optic nerve at the base. You can watch the full eyeball dissection here: http://youtu.be/VK-x-8-JMwY

 Fantastic submission, thank you!
