problem faced : Liberty Sport was in need of a new frame style to continue its Z8 youth collection. They wanted to design a frame for active teens that can be used at school and at recess, eliminating the need of two frames for those activities.
how and why the problem is solved : The frame has been designed to put up with shocks and drops. It is made of a double injection of plastic and rubber that allows the glasses to flex and bend in any circumstance. From a fashion point of view, this manufacturing process allows a dual color frame. It gives a sporty look to the kids. The Y40 stands out as fun in a conservative field and the tall rectangle eye shape allows the frame to compete on the prescription market. The Y40 is branded by Liberty as virtually indestructible, providing comfort at school and durability at play for active boys and girls.
