AST-2 is the latest innovation from Ultra Optics.  AST-2 was developed to provide an improved hard coat for non-tintable and AR applications.  This new coating provides the highest level of scratch resistance of any back side coating available in the market.  It improves upon our successful AST-1 by having significantly better adhesion to all lens substrates.  Additionally, AST-2 has the lowest yellowness index, which provides the highest clarity of any of our coatings.
