I have some Costa del mar in the grey shade and they have worked well for me. I can't remember exact but they were pretty spendy. Anyway, I had to buy those when I took off a pair of Action optics I used to have and set them down on the back of my boat at the lake, told the kids to get in and lets go. Took off on full plane. 30 seconds later I realized the reason it was so bright outside was because I am a dumbass. It costs a lot to be stupid.
