Great idea, but I havent handled epoxy san stuff like that and I since we are in quarantine, everything is close and there is now allowence to walk around.OEM lens or a really good repair. Getting the rough edges to align will be a challenge, though I could see a cool set of "stitches" with epoxy to hold those together. Bright red thread as the stitches could look incredible.
Here is what it might look like. Could use clear monofilament line or fine copper wire, all embedded in CCA glue. It is not the aesthetic for everyone, I know. Though showcasing your skills to keep your favorites on the road a few more years is great fun, IMO

Still awesome that you thought out of the box and believe me I would wear something like that if I could keep my precious glasses.
