I've been eating pineapple in the last few weeks to see if it gets rid of my eye floaters: https://www.benjamineye.com/blog/eye-floaters/ > Three months later, out of 120 subjects in the first group (1 slice), only 35 still experienced eye floaters, an improvement of 70.8%.

Has it been working for you? I've read the paper and am very curious.

I think I've noticed a mild improvement, but still a bit early to tell! :)

I bought some cheap prescription[1] glasses ($20) just for computer use. They put optical infinity at around the distance to my monitor (~60 cm)[2], which keeps my ciliary muscles fully relaxed.

Desired distance in cm here I'm assuming?

I've had eyesight issues since early childhood (strabismus, ocular dominance). This seriously hindered my efforts in basketball during middle school and also later on -- but I loved books and was good in writing and thus couldn't stay off computers, which resulted in years of constant eye strain problems. I bought an IPS monitor when they were really expensive, and ate an insane amount of carrots, both raw and cooked…

Do you have eye strain just from screens or also from reading books? If it's just screen related then there might be some fix in the future, I think of computer screens that do not cause any eye strain at all.

Both probably, but it's much less of a problem with books (I do remember eye strain after reading for 3-4 hours in a row, but I suppose this is normal).

I have an e-reader, which feels great. And I do wait for e-ink displays with consumer-level prices. :) I've read a lot about all the "Kindle as a Raspberry Pi monitor" hacks, but a more straightforward solution would be great.

In metres. (The unit for SPH on a prescription is the diopter; 1 dpt = 1 m^-1.)

You can also just wander over to a pharmacy's glasses rack and hold some reading glasses in front of your normal ones to test how much SPH you need to add. (Optical power is approximately additive.)

I should have noted: if you don't wear glasses already, or if that the formula gives you a SPH > 0.0 and you don't have astigmatism, then there's no need to order prescription ones. You can just go to the reading glasses rack in any store and buy ones with that SPH.
