I have a friend that had it..and she loves not having to put on her glasses first thing in the morning. She says that's the best part... She is 51.
I tell my sister she should have it. She has 20/220 vision in one eye... I think it would help her so much.. but she is also a cautious sceptic...
Sorry I can't give you any advice. I hope you find someone with a little personal experience..
