Well, there's the proof that everything is working as it should! A tumour would affect things from the inside and the pinhole wouldn't sharpen at all, so all you've got is what I've also got: completely normal variations in your vision

You're exactly right about the glasses too - they're unnatural and it's literally impossible for opticians to craft THE perfect lens for your eye or anyone else's because if you were to take a microscope and zoom right in on the surface of any human eye, you'll get bumps and abbrasions which affect how the light comes in. Some will have bumpier surfaces than others, some (like me) have developed astigmatisms over time and that's even harder to work with as well - and even if they could map a like-for-like lens on for the eye, it still will show up ghosting because the glass sits separate from the eye itself and won't be able to bounce the light at microsopic accuracy to make it go away completely.
^that is what I learned after at least 3 years of worrying about something that just turned out to be completely normal, it's just not that many people talk about it for some reason! And congratulations by the way! That's amazing news!
