Hard to answer since the instructions were not in English. One thing I do know is that you can't use the flash feature when lens is attached. But that's all I really know. Is there a way to tell?

Yes, the lens is glass. No tools, no instructions, but it's easy to install.

I don't know what your old lens is, mine was a screw mount. No, there is no glass, it is just a metal ring.

Plastic. But replacing them was not much more than getting a professional to clean the fog from the lenses.

There is no glass inside this adapter, it is all metal. I have used it to adapt a rokinon lens to my panasonic G-1 4/3rds camera and it works perfectly.

The lens is clear glass and it is convex with just about a 1" rise at center. Gorgeous, show quality light that I have had on my fatboy for there years now. It is still perfect.

Lens is clear plastic. Body and rubber outer gasket are black/grey-black. Once installed, they look like original equipment. I am very satisfied with the ease of installation and appearance.

Sorry, all the inexpensive lenses are plastic. Just be careful you do not place them lens down on a surface.

Lens is Glass, head is plastic, has flip up lens cover (gets in the way so removed it) T5 circular bulb does have nice cover that provides a crisp almost LED like bright white luminescence, absolutely worth the purchase only drawback as stated is origin of manufacturing china; and I strive to support our nation via USA purchases!

It appears to be glass, however I have not broken one so I cannot tell. They seem to heavy for plastic.

by tapping on the materials, it appears to me that the eyepiece and IR flashlight lenses are acrylic and the objective is most definitely glass

The lens housing is made of plastic. This lens is sometimes referred to as the " plastic fantastic".

Neither. Mine came in a plastic sack, with the lenses cracked. Horrible packaging.

I think they are glass. I like these binoculars so much that I purchased another pair for my son in law. He also likes them.

Metal. Some of the other parts are plastic and it helps with keeping the lens weight down. Excellent lens.

It is plastic. For the price I am happy. Even with a long lens the locks hold. It would not be suitable for a professional.
