EXPERIENCE BLUE BLOCKING HIGH DEFINITION: Increase Clarity. Increase Contrast. See Farther. HD (High Definition) lenses filter out blue light in the UV spectrum which cause haziness; leaving a clearer and crisper view. Perfect for Driving, Golf, Cycling, Running, Fishing, Tennis, Baseball, Watching the Sunset or Lounging by the Pool.
WHY FILTER BLUE LIGHT?: Blue light exposure increases the risk of macular degeneration. Blue light penetrates all the way to the retina (the inner lining of the back of the eye) and can potentially damage the light-sensitive cells in the retina.
