Burnt Umber Gradient
POLARISED : CATEGORY III : BLOCKS 85% OF VISIBLE LIGHT
Burnt Umber Gradient lenses start as dark as the solid brown lens at the top, but get gradually lighter towards the bottom of the lens. Commonly found in fashion sunglasses they have polarisation for exceptional glare protection and are a solid all-round performer and ideal if you own just one pair of sunglasses. Brown works well in mid to bright conditions and highlight things against green backgrounds. Brown lenses naturally filter out high frequency light waves and as a result has an image sharpening effect.
They have a discrete anti-reflective coating on the inside and an extra hard coating on the outside to assist with scratch prevention.
