> Pro tip: you can get very cheap (as little as $3) myopia glasses from aliexpress or a bit more expensive zenni optical. So there's really no big barrier to entry. Pro tip: with 6 diopters, make damn sure you get your PD correct. Otherwise the headaches you get from the induced prism just won't make it worth it.

I had no issues with that luckily, but if you order a custom prescription, many aliexpress sellers also ask for your pupillary distance. With zenni you always give your PD I think (I haven't tried it, but zenni is very popular in the endmyopia community).

  Could be working in your favor. Most off the rack glasses are made with a 60mm PD because that's a good average. So if you have, say, a 62 mm PD and you're wearing them to use a laptop, your eyes will be converging a bit anyway. It is much worse if you have a narrow PD, say 56. Before convergence, you already have over 2 diopters of prism wanting to spread your eyes outward.

    Oh interesting, thanks for letting me know. I'll have to look into that topic a bit more :) My PD is around 64mm and I'll be receiving glasses with that PD soon. It will be interesting to see if I notice any difference to my other glasses.

      You're welcome. And just to clarify, I don't have anything against your process (I've used Zenni myself), I just wanted to make the point about being careful with the PD.

        Oh no worries, I didn't understand it in a negative way. I'm always happy to learn new things - especially in this case as it does sound important and I haven't really been paying attention to PD.

Most (all?) of the cheap online retailers allow to (some require to!) enter a PD value and also provide instructions on how to measure it. I personally use https://www.goggles4u.com/ https://www.goggles4u.com/, they are cheap but not quick since they probably order from China.
