As mentioned I use prescription lenses. My prescription is quiet strong so my lenses are usualy pretty thick.
The only option is to go for expensive prescription sunglasses. This means the highest index lens that you can get, which currently is 1.74's.
I personaly go for G15 1.74 lenses. These are green non polarized lens. Polarized lenses are not that great as you can't see some LCD instruments. I personaly find green or orange lenses to be the best for flying.
I always go for frameless glasses that have the thinest arm that I can find (and like). My lens is 47mm in diameter and 27mm in height, like i said my prescription is strong, yet with the 1.74 index my lens is only about 3.5mm thick. I have absolutley no discomfort at all when I use them with DC headsets.
Here is my prescription from my last order:
Sphere Cylinder Axis Add PD
Right: 3.50 -3.00 30 59
Left: 3.50 -3.00 165
My last pair cost me about £140 with the lenses I mentioned above. And here is a link to the glasses I have. And yes the frame(less) only costs £22 the rest of the prices is for the lenses!! incidentaly it is a great website for prescription and non prescription.
