Maui Jim or Costa's for me. I have measured 20/10+ vision and can not wear plastic lenses as the distortion gives me a splitting head ache. My eye doc says this is somewhat normal for people with sharp distance vision to get headaches from slightly distorted lenses. Until about 15 years ago I never knew what caused my head aches when I wore sunglasses. Sadly very few companies are left making super clear optical glass lenses. Even the Maui Jim's with polycarb lenses I can't wear without getting a head ache.
I just keep hoping that Maui & Costa don't stop making glass lenses. Good vision is a plus and a minus..
I own three pairs of Maui Jim sun glasses all with glass lenses the youngest pair is now five years old and the oldest is over 15. No scratches and the frames are still tough as nails! Sat on my driving ones about 8 years ago and totally mashed the metal frames. I carefully & slowly bent them back into shape and they are still performing perfectly to this day.
My glass lenses last for years and years and years with no scratches, something plastic lenses, no matter how expensive, have never been able to do. My wife has a pair of Maui polycarb lenses and a pair of Maui's with glass. Her Maui glass are now 9 years old and the lenses crystal clear and scratch free. Her 1 year old plastic lenses are basically totaled..
It all about the optics for me. Just like there are low quality telescopes, binoculars and camera lenses there are also poor quality sunglasses when it comes to optical clarity. Ever try a set of Leica binoculars? Next time you try on sunglasses go outside and look into a tree with a good pair of Maui's or Costa Del Mar with glass lenses vs. a less expensive pair of polycrab ones. The sharpness difference of the leaves/branches on the trees will be quite clear.
Show me a pair of cheap polarized sun glasses with the optical quality of Maui's or Costa Del Mar, and glass lenses, and I'll buy a dozen pairs today!! Has not been done, trust me I've looked, really, really hard...
All that being said I can't for the life of me understand all you guys who lose sun glasses? Do you loose your wallets too? Get a set of leashes and actually wear them on you like you do your wallet. Still have all my "expensive" sunglasses..
If you don't need the optical clarity that some of us do, in your sunglasses, then don't buy expensive..
