R.Eng. sunglasses are a good product just be careful about lens size. They sell the same frames,(styled the same), with different lens sizes. 52, 55, 58 width. I am 6 1" a 58 lens looks pretty good on me, 55s not so much and 52s are kinda comical.
If you are looking for something under the $250 R. Eng. s will cost, jump on EBay quick and search Maui Jim Waterways. They are an "Aviator", but they have nylon frames that won't get all bent up. Hi quality, lightweight, GLASS lens (best lens Maui Jim makes). Looks like a shop owner is selling off old stock (waterways were discontinued 2 years ago ---styles change). I wear sunglasses almost all the time, and I have a bunch of them. The waterways I own are one of my favorites. At $140 you can't go wrong with these. Good looking glasses.
They are a nice looking pair of glasses too, just google Maui Jim waterways review and watch a video on em.
If you are stuck on wire frames, you will find a Seringetti Marco on amazon for $127 again a discontinued style but just "killer". Maui Jims are probably a teeny weeny tiny better on optics (???) (don't think you'd notice) but the Marcos are photocromatic, glass lens, and they look sharp.
If I were your Dad sending you a pair of sun glasses, I'd choose the WaterWays; awesome optics, they will last longer than wire frames and why would you want to look like everyone else in their wire ray-bans. That said, when my wife gets a vote and wants me to look good she votes for the Marcos.
I know I know TMI -------- but I kinda collect these things. Seriously, I'd jump on either of these deals kinda quick.
