None finer than Oakley. Optical quality is second to none.
I worked with my local optician, had custom no-line bifocals made with a narrow close up section at the bottom and a wide far vision section across the whole top of the lenses. Frosted on the edges and transition. The optician called everyone. No other manufacturer or third party lab could do what I wanted except Oakley.
I tried hard to hate Oakley and did for a long time but should have done it a decade ago.
