Thanks Jason,
I have wised up to the hair product thing, after years of ignoring it! I do clean with lens cleaner, but I think the head and hair thing is the main issue for me. I have ruby lend Juliets from 2000 too, and the lens are like the day I plonked £250 on them, but I have never put these on my head, even inside, the glasses stay on my face! I will get new lenses later on in the year for my Scalpels.
Thanks again, Paul.
