| "If you have headaches, especially chronic ones do yourself a favor and have your eyes checked, you might need glasses without realizing it."
Glasses are a good way of weakening the eyes even further. Eye exercises are a better way of keeping you vision in good shape. Keep your arm extended, focus on thumb, slowly bring it as close as possible. Extend again.
When reading a page on the computer, avoid scrolling line by line with a mouse as you read. Better for the eyes to use the space bar to do page scrolling.
If you find reading a book is out of focus, you might wait for 10 seconds or so, for the eyes to focus. Happens if you are not used to focusing on near objects.
Not sure about the scholarly literature on it, but my eye doctors (several different ones over the years) have almost always mentioned how it's better to slightly undercorrect the vision, so that the eyes still have to work a bit at focusing. They implied that to do otherwise could speed the degradation of your vision.
I am from the East. We rely on common sense and what has _actually_ worked for us in our life, and what has worked for generations. I take studies done in the West (esp wrt health) with a pinch of salt. (Which reminds me of the fad about low-salt for which their are many authoratative studies and research but its still not true)
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.
