I don't do anything more than take frequent breaks, and I've never had trouble with headaches like this. Maybe you should see an ophthalmologist or optometrist. You may need glasses or a different prescription for whatever lenses you might already have. Or you may have some other vision-related issue that needs diagnosing.
