I'm sorry if this has already been posted, but I have looked and couldn't come up with the answer, or find a post about it. I am trying to find out how to replace the lenses in my Water/Racing Jackets 1st gen I think around early 2000 they have non-folding legs some have vented lens and some don't, some have the strap on the legs to go around your head to keep them while in water or whatever and some don't. I need to know how to get the lenses out of the frames safely and how to put lenses back in the frames without damaging the lenses or the frame because I need to replace the lenses in a pair I have. Since the frames don't open up like the new Racing Jacket or like Jawbones I have. I'm not sure how to get my lenses out. If anyone could tell me how to do this or send me a link or anything that could help me get these lenses changed out that would be a great help. Thanks for your time in reading this, and thanks in advance for any good advise on how to change out my lenses in my Water/Racing Jacket. Have a great day.
