Dear Dr. I took prodep 1 capsule, later increased to 2 capsules. while taking prodep, I got blur vision, specially at night I could not read boards with lights, it was blurred. Later I had to go out for a project, it was in a rural area. So I stopped it at once, now I have stopped it for one year. But still I have blurred vision, objects at long and short distance. I would like to know, is it because I stopped Prodep at once. Thank you.
