Regarding the fine detail, firstly I think people generally had better eyesight back then.
Secondly, jellyfish. One type, always washed up on my local beach, is a 3pi/2 arc - about the size and shape of a 3/4 donut. And perfectly transparent. Its optical qualities are something any curious human will investigate. It's a small step to use it to see and work on fine detail. And much smaller steps to experiment with which curvature gives the best magnification. Could also be used as a telescope. Jellypunk.
