BZ Optics Pho Bi-focal Polarised Photochromic Sunglasses

PHO Frame with Photochromic POLARISED Bi Focal Lens.

Lens will change from Cat1 light grey pre-dawn or low light to a dark grey Cat3 as the sun intensifies and the UV increases. Polarisation cuts glare, especially on the water.

The TR90 super lightweight hybrid frame has dual moulded non slip flexible temples ideal for wearing under open or full face helmets. The adjustable non slip nose piece ensures optimum fit and comfort for all face shapes.
