Can anyone tell me how to mount the iris on Varga shooting glasses?
only one plastic tab and no instructions.

The rod of the lens holder fits through the tab and it attaches that way. At least that is true of the pistol version (37mm). You can use it with our without a lens mounted in the holder.

The black tab on the iris has a small hole through it. This slips down over the shaft of a lens holder. Iris sits behind lens (closest to the eye).

It took me a while to figure it out too!
