All DVX Sun + Safety lenses are made from shatterproof polycarbonate. This is one of the world's most impact resistant materials for safety in any situation.
Each Lens has a scratch resistant hard coat, for years of optical clarity under rugged use conditions.
All lenses meet ANSI optical clarity requirements. This means A) objects at a distance remain sharp, B) the size of objects remain true and C) prismatic power is maintained, meaning the spatial relationship of objects in the field of view remain true.
