Scotopic?: If your vision has been corrected and you still have these symptoms, you may have a problem with sensitivity to light as reflected on the printed page. You could try to read with a colored overlay or different lighting. Fluorescent lighting may be the problem. Have an eye specialist examine you first then try changing the backgrounds or lighting.
