Black Onyx
POLARISED : CATEGORY III : BLOCKS 85% OF VISIBLE LIGHT
This dark grey/black lens is one of the most popular sunglass lens colours for general use. They have polarisation and a discrete anti reflective coating on the inside for exceptional glare protection. The smoke tint can provide anti-fatigue benefits and shows true colours, so is a must where colour recognition is important.
And, with an extra hard coating on the outside to assist with scratch prevention, they are a great lens for fashion frames while also being exceptionally functional.
