The Brand
BZ Optics is a unique eyewear brand developed 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 sunglass business. Scott needed a sunglass that he could train in at all hours of the day. A lens that would be clear before dawn or in very low light conditions but would darken as the day progressed and UV intensified. This sunglass should also enable Scott (who wears reading glasses) to read his digital computer on his handlebars and small print on his watch while running without the need to switch to reading glasses. Sourcing a photochromic lens with optional bi focal inserts involved a 12 month, world wide search. This world first lens was sent to Kevin's frame manufacturer to develop a super light weight cycling frame adaptable for all face shapes and sizes and for wearer comfort under even gruelling conditions.
