I have this memory of seeing this really chilling black & white film or Tv segment. I thought possibly the twilight zone but I cannot find it when I do a search. I’m not really sure much of the other context but I remember that it was black & white and the lead character is either born blind or just has difficulty seeing and he starts to take these special eye drops that will allow him to see or see better. Anyway through out it all as he is taking more of these eye drops they also allow him to see things others can’t and he continues to take more and more until he see what I believe is the future and it drives him absolutely insane. Please help me find this, I’ve been wanting to watch it again for nearly 20 years now.
