Hard coating	AR coating/Hard multi coating	Super hydrophobic coating
makes the uncoated lens hard and increases the abrasion resistance	increases the transmittance of the lens and reduces surface reflections	makes the lens waterproof, antistatic, anti slip and oil resistance

To develop a new progressive lens in a high quality level, extreme complex and powerful optimization programs are necessary.To simplify, you have to imagine that the optimization program looks for a surface which combines two different spheric surfaces (distance and near  vision) as even as possible.It is important, that the areas for distance and near view are developed as comfortable as possible with all required optical properties. Also the transformed areas should be as smooth as possible, that means without big unwanted astigmatism. These punitive easy looking requirements are practically very difficult to solve. A surface has, at a normal size of 80 mm x 80 mm and a point distance of 1 mm, 6400 interpolation points. If now each individual point gets the freedom to move within 1 mm about 1 µm (0.001 mm) for the optimization, with 64001000 you have an incredible high number of possibilities. This complex optimization is based on the ray tracing technology.
