Hello, Anyone else with this experience? Since I have been taking Carvedilol I have had eye problems, I take a low dose, just 3.125mg per day, (should have been twice a day, but side effects too bad). The main problem is eye disturbances average twice a week. Will start with everything feeling too bright and vision becomes fuzzy, then flashing lights in vision (even with eyes closed) & typically a round zig zag image in centre of the flashing lights. This lasts usually about 30 mins but can be longer, accompanied by tingling on left side of face and slight numbness that goes into shoulder and down arm. Whole episode usually about an hour. Not much sympathy from cardiologist who says this drug can be used to PREVENT migraine.
