My eye doctor has this spaceage device called an Optomap that takes a picture of the back of your eye - the retina. I was getting my eyes checked a few weeks ago and had my eyes photographed using this system. The images were amazing. I asked my doctor if I could get a copy sent to my email address. (Yes, I am a total geek!) Here are Optomap images of both my right and left eyes. My eyelashes appear at the bottom of each image.
