No. When I attach them I use a Plexiglas welding solution on the edges of the lens. It works about as well as Super Glue on the Gel itself but is fantastic for Plexiglas. It is about the only thing I found that keeps it optically clear.
I was intending originally to coat the whole lens and attach the Gels but could not get it where there were absolutely no bubbles. Too bad though. The couple of experiments I tried looked perfect... except for the bubbles.

The Gels will be difficult to put in unless they are attached to the lens but I think users should be able to accomplish it by taping a couple of pieces of scotch tape on the two upper tabs of the lens that jut out over the handle hinge to the gels same tabs protrusions.

If I find some time after things stop crashing on me and I can figure out how to make the page, maybe I'll make up a simple instructions sheet on how to install them.
