Caffein/tobacco and Glucosamine

[LadyPit]

I know that smoking is bad, but what about caffeine ?

I have also been told that glucosamine (Joint supplements) is not good for your eyes and could elevate pressure. How true is that?

Interesting. And Dukey is touting caffeine as a possible treatment for myopia! I drink a cuppa every morning. Anything more than two makes me agitated! Someone posted here before saying glucosamine makes the eyes dry.

There was a small study a few years ago that suggested that patients who drank more than 5 cups of caffeinated coffee per day could raise the eye pressure. I haven't seen that repeated. I'm not aware that glucosamine can harm the eyes but anything is possible.
