How to change lenses on Simmons' glasses

[epags]

Problem Solved. Thanks to Laphroaig!
Just received a set of Vintage Simmons Shooting Glasses with two sets of colored lenses.
Not sure how to remove and replace the lenses. Nothing on YouTube. Anyone have instructions? Notice the notches and the 'wire' hooks.

They look alot like Decot Hi-Wyd's. This video shows them popping the lenses in and out several times. It should give you a hint on what to do.



I might take my lenses out wrong, I just pull them out from the hook on the temple side. I put them in like they do, rotate the lens up until it snaps into the notch, also on the temple side.

Thanks for the lead. It is almost the same but I found the trick is to push on a little spur behind the 'clamping bracket' Problem solved. Thanks again
