okay so my partner was having vision problems
and instead of going to an optometrist he made up a bunch of calibrated charts to measure his own prescription (which is not a simple one) like "no, I'm an engineer, I know optics, I can figure this out" and just ordered direct from Zennioptical and went around for like a year with these self-calculated glasses while I kept saying will you please go to someone who actually has a degree in this stuff instead of doing this extremely engineer thing
and today he finally went to a real optometrist
who said that he got the prescription right
this reminds me of my friend who has decided it sounds easier to build her own fNIRS machine and then train herself to focus using than rather than go to a doctor and get Adderall
