belatedly: sweet, thank you for these answers, and I have one more:

apologies if I have missed this somewhere, BUT — if peter were to, say, suddenly need to acquire glasses (because thanks, no longer having spider-abilities means having shitty eyesight once again), would there be a place to obtain said glasses?

which leads on to: peter parker, eternally broke, eternally unable to hold down a steady job, quite obviously has no money — stuck with shitty eyesight until he can afford glasses?

(I am cool with any option.)
