My ophtalmologist said something among similar lines. It seems that using glasses with the same strength for reading/screenwork and normal activities (e.g. being outside) can have bad effects on your eyesight and actually make it worse over time, because you do not train your eyes enough. He recommended to me, that i should use two different glasses for when i need to work in front of the screen and for the rest of the day.
I used to have no glasses at all, and got severe headache attacks that would last for days. I then went to see a doctor and they found out that i was overaccomodating my eyes, and that i needed a pair of strong glasses, to relax the muscles of my eyes since they were constantly cramping trying to automatically make up for the loss in eyesight.
