Well garymh, I can assure you these glasses were never immersed in water, out on the hill on a morning, binoculars fine, driving rain so I put them in my gortex jacket pocket. On the high ground I removed the glasses and they were fogged up. 2,500 feet up and I have the Queens cousin as witness as he was on the hill with me.
So don't come this certainly caused by immersion in water rubbish.
THEY WERE IN MY POCKET.
What you have not mentioned it that they were serviced in 2008 whilst a dent to that side was being repaired, funny EH !!!
Just adding ;
Anyone who was on the west coast of Scotland in the first week of October will agree that it never stopped raining all week, day and night.
I was along with my friends, going to the hill each day in damp tweeds and boots. However, they all had binoculars that didn't fog up, am I supposed to leave my binoculars in the lodge on wet days, in that case I'd never have had them out that week.
