BZ Optics

BZ Optics is a sports eyewear brand from Tauranga, New Zealand, with the motto "Innovative Active Eyewear". Its core model is the PHO, a light, flexible half frame with non-slip temples, an adjustable nose piece and small clips that let you swap the lenses without tools – from mirrored Cat 3 lenses to photochromic, polarised and clear ones. By its own account BZ Optics built the first photochromic bifocal sunglasses. Alongside there is the narrower LJM for smaller faces and the CRIT with a single shield lens.
