Scratches and damage to the mirror coating on goggles is all too common, and often results in the mirror film coming away from the lens over time. Swans have addressed this issue and introduced the MIT Lens - Mirror Insert Technology. The mirror film, which is usually applied to the outside of the lens is sandwiched between two tough, protective polycarbonate layers which prevents scratches and damage, and prevents the mirror coating from peeling away. This is achieved with negligible increase to thickness of the lens.

Furthermore, our next generation of mirror films give a constant and consistent colouring around the curvature of the lens, a feature which has been unseen before in other curved lens goggles.
