I have a long running post on the effects of the VieLight on my husband. I can no longer find the comments that come to me to respond to.Connie (I believe) asked if the VieLight has any effect on the sense of smell. My husbands sense of smell did come back. I didn't think to attribute it to the Vie Light. It was just a curious thing that seemed to have happened. Now I believe that is why he can smell again. It's not as good as when he was young, but he can smell, even things like wine.
He has kept the good results he has had in the last 2 years with the VieLight. He doesn't have cognitive loss.
