Tommy O'Gara and Shinsuke Takizawa created a pair of optical glasses with sunglasses clip that gained iconic status through the test of time and sparked the launch of the 'Four' in 2012. The frames are made from a cellulose-based acetate which makes for a harder more durable pair of glasses compared to those made from more common petro-chemical plastics. As well as being eco-freindly the colours appear brighter than those produced in more traditional materials.
