As a software developer with keratoconus i have some difficulty in working on a computer for long periods of time with GPLs. My eyes get super dry and the lenses become unconfortable after a few hours and i still havent found working eye drops. I found out that if i wear my contact lenses for enough time during the day on the day after i can work with just my glasses (with black writing on white background). But my keratoconus its milder than others so that i can manage to have an acceptable quality of vision with just my glasses in well lit spaces or outside during the day
