Im 29 and i was taking propranolol prescribed to me by the er. I took them for two weeks then i started to notice my vision change. I have light sensitivity i can look at car headlights or be in the sun too long. I cant look at anything bright i lost some of my periphil vision and everything is starting to become blurry. I dont know if this is permanet or not but i feel like i'll be blind in the next couple of days. Can anyone help are there any cases of people going blind from propranolol.
