let me answer some questions that i know some of you will ask: no, i don't feel weird posting my retinas. these pictures are amazing. the eye is a fantastic structure, and these photos confirm that indeed my eyes are also fantastic.
if you know me, you might know that i am extremely disturbed by the idea of eye damage. i can't wear contacts for fear of hurting my eyes, and any time i see eye damage on tv or in movies i shudder and literally freak out. i jump up and down and cringe and just hurt hurt hurt
my classic example of eye damage in a film that freaked me beyond belief: demolition man. recall the beginning, when wesley "always bet on black" snipes escapes the prison using the warden's eye to pass the retinal scan. freaky! ugh! just the thought of it makes me quesy. but but but i decided to google the movie to find out what others say about the eye scene. i was so heartened by this find, which describes the scene as factually void:
Factual error: Simon Phoenix uses the warden's removed eye to escape from the cryoprison. The eye is on a spike, which would have not only destroyed the shape of the retina, but blocked the scanner from reaching it as well. There's no way the retinal scanner would have let him pass.
this makes me feel good, to a certain extent. sure, any crazy criminals who have seen this movie and need to get into my retinal-eye-scan-locked fortress might think of pulling a wesley snipes on me... but it's more likely that they'll think through the problem and realize that taking out my eye in tact is likely a difficult job. and so maybe they'll let me live.. at least leave my eyes alone!
Thou hast no speculation in those eyes
Which thou dost glare with!
