Since I work for an optometrist I can help you here ;) You don't necessarily need to have blurred vision to need glasses. I sounds more like eye strain then actual vision issues. And if your using computers and reading a lot at work than this is most likely the cause of your headaches. You may need to have glasses for Screen Based Equipment (SBE) in which it may just be a light script just to take the strain off the eyes. I don't know what they're called in America but here they are called Access Lenses which are specifically made for looking at computers and reading. Some work places actually pay a bit towards the glasses for you if you get an SBE form filled out by your optometrist so check with your work :) Make sure you tell your optometrist that your mainly having the headaches at work too. Hope this helped!!
