A glass photochromic brown lens base with a high-definition filter.
When fishing in low light conditions, you want as much light to reach your eyes as possible. That way you get as much detail as you can of what you are looking at. At the same time, you want a lens that will allow you to wear it as the available light increases without becoming uncomfortable. The G1HX lens will lighten if available light is low and darken when available light is high, giving you the best of both worlds. This lens is fantastic in the early morning in inshore waters or on rivers and streams. Suitable in shady, or low light conditions.
It is also a great driving lens for snow and off-road driving delivering ample light to the driver while reducing glare.
