I have glasses too but for long distances. Although i wear it when i read. It was needed for me because my eye focuses on short distance a lot, and it 'forgets' how to focus on distant objects as I dont look far that much because I watch a lot of monitor. In your case I assume that your headache was cause by the struggle when you cant recognise letters easily.Originally Posted by Gabriel1
And for me books dont cause this headache. Only monitors.
