About BZ Optics
BZ Optics are an Australian sunglasses brand started by Scott Birdsall - an avid cyclist, canoeist, sailor and triathlete and Kevin Barr a surfer and sailor with 40 years’ experience in the action sport and sunglasses business.
Together they developed the World's first bi-focal photochromic sunglasses, featuring high impact UV activated lenses which transition from clear pre dawn or in low light to dark in full sun.
Sourcing a photochromic lens with optional bi focal inserts involved a 12 month, worldwide search. This world first lens was sent to their frame manufacturer to develop a super lightweight cycling frame adaptable for all face shapes and sizes and for wearer comfort even under gruelling conditions.
