The treatment that protects your backside
40 % The lenses returned for scratches are for scratches on the backside of the lens. Under normal wearing contitions scratches occur on both sides of the lens. Both sides of your lenses get dirty... both sides must be cleaned. Unfortunately, as you will discover, the cleaning process is abrasive and can cause scratches on both sides of your lenses.

TD2 technology allows for innovative uses. It is specifically formulated to optimize the scratch-resistance of each individual lens material.

TD2 is tough
TD2 intergrates glass-like silica particules into its polymer matrix. They impart a hardness and scratch-resistance that is superior to other scratch-resistant coatings available.

TD2 is Two sided
TD2 is developed for consistency and effectiveness on both sides of the lens, no matter what desing or material it protects. With TD2, both sides of the lens are coated for dependable and equal protection.

TD2 is durable
The ploymer matrix provides the flexibility required for the expansion and contraction of plastic lenses. If the hard coat is too rigid, any expansion, contraction or impact can crack the hard coat. TD2 creates a tough, yet flexible, protective layer by intergrating the flexible ploymer matrix with the glass-like silica particules.
