  Spectral Control
"Control is the operative word here
By filtering out specific colors from the visible light spectrum ,Spectral control technology gives you stunning, high definition contrast and color enhancement. This essentially gives your eyes control over the light, resulting in crisper vision and amazingly clear images, while blocking out most blue light for
 less eye fatigue"

Photo-chromic
The ability of the lens to adapt to the surroundings instantly.Embedded molecules within the lens are designed to constantly adjust to changing light conditions to allow you eyes to stay focus
on the shot or the ball.

Polarization
Because glare is the enemy of clarity.It may be beautiful scenery, but if light is bouncing around and off a myriad of surfaces and into you eyes you will not see clearly Polarization cuts down tremendously on the aberrant light passing through the lens and into your eyes, and thereby improving the clarity
 and contrast.The polarization inherently makes the lens essentially 100% UV Protective.

Anti-reflective Back Lens Surface
Prevents back lens surface reflections from entering the eye which can cause glare.With less glare there will be more contrast.
