> The weird thing was that I'd use my computer at home and definitely absolutely could not see a word without them. I'd get to work and, same monitor, distance, resolution, could still read just fine. I chalked it up to dehydration or just being tired in the morning. But then I go home and couldn't read my home computer again, which was weird.

Blood sugar, diet, stress, exercise, etc. also can all have a noticeable effect on vision. When my vision goes to shit, I think back over the past couple days of how my diet has also gone to shit (it's the holidays!).
