An optical work of art

Norville recently sent me the results of a project it has been working on to provide Rx lenses for the nannini Swing sports frame. The project may not result in a product for sale but the results are stunning from an optical lens manufacturing proint of view . Having been given the opportunity to try the results I thought I would share my good fortune and give my view.

The manufacture of sports lenses for the swing frame requires notching at both sides and reccessing around the top edge of the lens to allow it to sit inside the frame with what looks like an intentional ventillation gap.
