Let me start out by saying these are the best sunglasses I've owned to date.
They are comfortable, stylish and very durable.
The lenses are simply incredible.
So here's the tech behind Nines.
The TR-90 Frame.
This frame uses a thermoplastic material which offers extreme comfort because of its flexibility and quality. They easily bend accordingly to your facial texture and and are very lightweight.
Nines even added an anti-corrosive coating to make these the "must have" sunglasses for every angler.
The lens.
Nines offers 3 different lenses.
Polarized Gray:
A great all around lens for the road or the water.
This lens is made for direct and harsh sunlight.
Polarized Amber:
A great lens for sight fishing that cuts out the haze of early mornings.
This lens is made for Hazy or Cloudy Sunlight.
Polarized Yellow:
This lens is made for direct sunlight. Colors and details will pop right out.
Hydrophobic Coating:
The Hydrophobic coating helps promote the run off of water droplets from the lens surface. Thats a huge benefit in the rain, on a boat or even when sweat gets onto the lens. The coating resists stains and repels grease from finger tips so cleaning your lenses is a breeze.
Anti-Reflective Coating.
The use of Anti-Reflective Coating blocks sunlight from entering from the back of your glasses and reflecting light directly back into your eyes.
The coating virtually eliminates reflections from the front and back surfaces of the lens and improves vision by reducing eye strain and fatigue.
98% Near Infrared Radiation protection and 100% UVA/UVB protection.
Lots of tech here. And for good reason. Nines lenses offer major protection.

Bottom line is that these sunglasses rock. I have the Sturgeons and Eries series and plan on picking up a pair of the Delta series (a dressier version of the nines line)
