They aren't cheap but I did take the plunge and bought a pair at the 2025 BMW National Rally In Tennessee last week. The frames are thin so they are almost transparent when sliding into my helmet. I rode back to Michigan and couldn't even feel them. My other DUAL glasses would squeeze on my temples, causing intense pain after a few hours of riding.
Kingfisher Narrow (Osprey) with Bifocals
These are great. From the front one can’t tell that the glasses are bifocals. Being non polarized means that video or information screens aren’t blacked out like they would be with polarized lenses but they still block glare and sunlight. I highly recommend them.
My wife has decided these to be the most comfortable as well as best looking sunglasses she has purchased. Many pairs later finally she is satisfied. Her RX is about 1.5 and after cataract surgery, feels this the perfect lens color plus 2.0 Bifocal lens as well as style.
These are the best glasses for flying,
