What if you can't even see a screen with out glasses? I'm -8 both eyes and I have to be like 6 inches from a 27" monitor to see words clearly.

Seriously considering lens implants since my eyes are too bad for lasik.

That's very common, you use weaker glasses for near work then, so around -6 or -6.5 depending on your distance from your screen.

You can find more information on that on the endmyopia page or wiki by looking for "differential glasses"

Thanks. I'll give this a try. I don't like the feeling that if I lose my glasses or contacts I'm helpless.

You're welcome! I get that feeling too, makes me uneasy. Best of luck on your eyesight improvement journey!

Where do you buy "differential" lenses? Do you just get a lower prescription from your optometrist?

I get them from AliExpress, because it's super cheap there. Some sellers only offer very standard prescriptions (same diopters on both eyes, standard pupillary distance, no astigmatism correction). Others also offer to create glasses with custom prescriptions, just like you'd get the glasses from the optician.

Zenni Optical also offers custom prescriptions, but is more expensive (likely still a lot cheaper than your local optician).

But you can totally also get glasses with a lower prescription from your regular optician, but as you will relatively frequently need new glasses, that can get expensive (at least here in Germany it would, and I heard in the USA glasses cost up to $1000).

I buy all my glasses online so I usually end up only paying like $250 but that's still a lot to just test this stuff out. I'll give aliexpress a go since it's so cheap.

Yea, that's definitely quite a bit of money. You could also try it out by wearing one of your older glasses for near work. If you still have a pair of older glasses that are around 1.5 diopters weaker that is.
