I was at the VA a few days ago for my eye exam. After your eyes are dilated they give you these temporary sunglasses so you can drive home. Looking for a lens filter to decrease the brightness of your LED display? These sunglasses are ideal. They’re not too thick and they’re easily cut to any size with a scissors. Like most stock configurations, I mount all my filters on the bezels inside. This often requires a thin yet ridged material like this. In many cases the distance between lens and the LED will not allow much thickness without them being tightly jammed together, or require an additional modification of the LED mount itself. IMO neither is desirable. Remember, you can always place these sunglasses over the front first before digging in. Maybe your CB would like to play ZZ Top, maybe not…
