Eight bore, I have the rubber cover on them. I think after 20 years or so they have gotten bent and worn and I can’t seem to get them back straight. Might be time for a new pair of frames.

Agree Stan, the reflection will flare many birds. I see decott is offering non reflective lens. I Might give these a try. Like you, I in the past I haven’t used my shooting glasses for hunting, but as the years go by I have trouble with contrasting colors. A bird against a blue sky has a pretty good chance of hitting the ground. One against a contrasting back ground disappears.
