Ignore the spikes LOL! But yeah, I keep that modded old lens in my wallet, in case I ever lose my glasses.

    how to find or even approximate that at home

    For you application, it¨s not too critical. But to make proper, dependable glasses you wear every day, I don’t even bother. I always go to an optician for anything to do with lenses. And I go to a proper eye doctor for prescriptions, even if it’s eye-wateringly expensive. I just don’t skimp on that.

    I mean I’m a cheapskate and I make frames because I don’t like to be taken for a dandelion and being grossly overcharged for simple technology that’s been around for centuries. Not to mention, I don’t like wasting perfectly good lenses just because the frames are broken.

    But lenses are generally out of my competencies and I don’t have the tools needed to work on them - nor do I want them, because I don’t need to rework my or other people’s lenses nearly often enough to justify the expense.

    So I let opticians measure my lenses and I order them ready-made and properly edged. I would like nothing better than to not bring any of my business to the eyewear industry for a variety of reasons, but it’s simply not cost-effective - or even safe - to DIY optical lenses in any way that impacts optical properties.
