I have been using Luxar and Luxar u AR coatings for a number of years from Optik k&r . I find the coatings scratch easily and often break down. The break down is noticeable where the patients eyebrow or cheek touch the lens. The coating does not do well when in contact with perspiration. The coating also seems to peel away from the edge of the lens after a few years. The lab has stood behind the 2 year warranty. Although it is a nuisance for the patient to return. The warranty jobs also costs me more staff time and wear and tear on my edger. Currently 25 to 30 % of my daily orders are warranty claims. Does anyone else find these percentages at their practice or are these returns excessive?

Secondly, if your returns are less, which supplier has a coating with better durability?

Thanks Mandy
