i'm a bit queasy and uneasy when it comes to anything having to do with eyes, but for some reason i find this photo fascinating:
it was displayed on flickr by mjulep and shows the rear of the eye after a dye injection.
our eyes are incredibly impressive and sensitive lenses. we try to mimic the behavior of our eyes in order to see the distant universe by making massive telescopes. but in reality, our eyes are much better than any of our feeble designs. i guess thats the advantage of 540 million years of evolution!
