Dear Anthony,
I've experienced something similar. Particularly when going from bright light (sunlight) to a lower flourescent light (inside a store) I actually have momentary blindness till my eyes adjust and now I can only read in natural light (wearing sunglasses of course) . As far as sensitive sight in the mornings, I experience just the opposite. After a good night of sleep, my cataract eye is less fatigued at least for a couple of hours in the morning, but I only have a cataract in one eye, so I get a reprieve. Actually I wear an eye patch on the bad eye for a few hours a day which seems to reduce eye strain on the good eye. Anyway, I think after surgery, your blind spots should be a thing of the past. Good Luck.
Lori
