I've been happy with my Smith Optics.

I'm an Oakley Flak Jacket guy with the polarized XJL lenses.
Never slip and blocks everything.

Oakley Prizm..... Maui Jim’s are nice as well.

Prescription Rayban New Wayfarer or Maui Jim's w/ contacts.

Interested in checking out Oakley Prizm's now though after reading this.

Maxx sunglasses. Best golf sunglasses I've ever owned. Reasonably priced and come with a lifetime warranty on the frames and lenses. Have used the warranty twice. You download a form from their website, fill it out, ship the glasses back with a check for $9.95 for S&H and you get a new pair in about 2 weeks. They come in several styles and are available in some golf shops or you can order online. They fit nice and I wear them full swing or putting. They never move.

I've been using the Oakley Flak Jackets with the black iridium lenses for years. I used to have a pair with the PRIZM lenses, but they just weren't dark enough for my liking, in bright sunlight it was still difficult to see properly.

I like the flak jacket design since there is no frame at the bottom, so nothing obstructing when looking down at the ball, and when wearing a hat they fit well.

I sent my VA prescription to SportRX and had it put in Oakley frames. Great!!

Check out REKS. I was wearing Oakley with prescription Golf Prizm Lenses. When I needed a new prescription I discovered REKS. Half the price of Oakleys and they have not disappointed me in any way. I wear them everywhere. I use the golf specific Trivex lens.
