Pros: Super light weight! Optical quality
Cons: You need both hands to put these on
If you ask me you just can't get any better than Maui Jim Sunglasses!!! These polycarbonate lenses compete well with the glass lenses Maui Jim offers. And all that Maui Jim offers is Polarized and blocks UV. As for as I know all the sunglasses are named after islands, beaches, golf courses or other Hawaii related things. I've had mine for over a year now and have not had any major problems to speak of. I own the Wailea's from the sport titanium series.
For those of you not familiar with polarized lenses here is a brief explanation. Polarized blocks glare/reflection. Glare and reflection can come from any flat surface water, ice, snow, sand, windows, roads, cars etc. Polarization acts like a filter or like venetian blinds. Light reflected from surfaces is generally horizontally polarized. This horizontally polarized light is blocked by the vertically oriented polarizers in the lenses.
I have a narrow face and have always found it difficult to find sunglasses that aren't to wide that look more like clown glasses on me. These wailea's "fit" the bill to a T. With a slight wrap, a smaller lens and a rimless design, they were practically made for my face. Not to mention the temples/bows aren't to long either.
In all circumstances glass is the best...optically. It's harder and does not scratch as easy but will shatter and crack if dropped or hit by an object. These wailea's however are not glass, but polycarbonate, optically Maui Jim is top notch so I'm not complaining. There is a benefit to glass though. Polycarbonate will scratch easier(see scratch coat below) but is shatter resistant, so if I'm riding a bike and get hit in the eye with a branch or am playing a sport and get hit in the face I will not get glass shards in my eye! As Martha Stewart would say "it's a good thing." Many layers make up these spectacular lenses. To start out with we have a polarizing film that absorbs 99.9% of harsh reflected glare, sandwiched between two layers of polycarbonate. It then has an anti reflective coating on the backside that prevents bounce-back glare and reduces eye fatigue. A bi-gradient mirror adorns the front which "squints" for you by eliminating overhead and reflected glare. As well as a silicone-based hard coat that prevents both sides of the lenses from scratching. And to top it all off it gets a water proof coating on both sides that sheds water and snow and makes cleaning easy. Essentially its like rain-ex for you sunglasses.
The frames are made of a beta-titanium alloy, which comprises of titanium, aluminum and vanadium for maximum strength and flexibility. The hingeless design hugs the side of your head comfortably without hinges or springs. And despite being incredibly strong and flexible these are so lightweight, coming in at an astonishing 11 grams. The silicone nose pads are comfortable and easy to adjust.
I needed some really good sunglasses for running and for camping in the boundary waters and these have done very well. The light weight is a huge plus for my running and the quality polarization is awesome for the 10,000 lakes we have here in Minnesota. Other than the occasional need to straighted these sunglasses I have had no other problems with them. The one frustrating thing that I wish I could change is that they require 2 hands to put on. They come with a new case that is much more streamlines than the old one they offered. And with sunglasses of this class and caliber you will want to store them in the case when not on your face....hey that rhymes!
A word to the wise: These may be spendy but don't bother looking for a bargain. I paid $249 so expect to pay that. Maui Jim sets there prices and can not legally be discounted by dealers. If you see a good deal and the company says they are authorized, call Maui Jim direct and they will be able to tell you if the dealer is truthful or not. If you see a reduced price, I guarantee the dealer is not authorized to sell them. They may not necessarily be knock offs though, they might be the real deal but if you run into problems and need warranty work done on them, guess what, they don't have a valid warranty. I got mine from Peepers.com and they have the full line of Maui Jims with may of them in stock and free shipping!
