I'm nearsighted with no astigmatism, so I have a simple -2/-2 prescription (if I remember correctly).
I sit at a screen 8-16 hours a day. I get strong headaches every single day, for which I keep a supply of ibuprofen at work and home. 400mg a day is generally plenty.
I do not wear my glasses while at the screen, as it's close enough that I don't have any issues.
I suspect my headaches are neck muscle related, not eyesight, but I haven't investigated further.
