I use
Pre-made "Original Style" Teal Mirror on Dark Density Gray Lenses | Zurich Rx and Non Prescription Sunglasses Out-Perform Polarized which fit over my prescription glasses. Strap instead if templepieces can be worn comfortably under a headset.
I've used these for about 20 years. Lifetime guarantee against breakage - when I turned up at Oshkosh with one I broke sitting on it the only question was what colour lens I wanted.
