These polarised fit over sunglasses provide all-around 360o protection from harmful UV rays and cut glare reflected off flat surfaces such as water, roads and snow. They're especially popular amongst fishermen because they remove reflected glare off the water allowing you see down below the surface. A polarised lens filters direct light and eliminates polarised light allowing the wearer to see light in its pure state. Objects appear more defined, sharper and naturally coloured. Instead of squinting to minimise glare your eyes will see colours with true clarity.
