Our eyes are not ideal for living in air. They're fish eyes that adapted over and over so they work well-enough in the air. I want to know what a purpose built air eye would be like.
Our eyes are pretty good at working in air though. The only thing that makes them fish like is that they have to stay moisturised really. I doubt that filling them with air would do much, we could maybe get rid of floaters though. The dumbest thing about our eyes is that theyβre inverted with nerves and blood vessels being in front of the receptor cells so Iβm wondering how much theyβd improve if they were properly constructed like in squid.
Yeah, my eyes are not great. If robotic eyes get developed in my lifetime and could work, and maybe see more than mine do (night vision mode, sunglass mode, other sorts of settings to see things my eyes can't) I would be an early adopter.
Our vitreous fluid has an almost identical refractive index to sea water, so anything we look at not in sea water is distorted to some degree and our brains have to fix it. They do a good job, but it could be a lot better.
I wonder how they would differ? Maybe more like a camera? Though that is pretty similar to ours.
If they were air filled, which would the best for refraction/distortion avoidance, how would the air get in there? Eye vents would be problematic when swimming.
Eye vents just sound weird....
Your wish is granted, you get bug eyes
those are crustacean eye derivatives
