I am working for a company who demands that this blue light coating is on more than 50% of lenses we sell. I have been an optician for 15+ years and I don't buy the whole gimmick on Blue light filtration coatings. They are expensive, not covered at all by insurance, not proven to be effective, and most cell phones and laptops have a built in filter. I don't see the benefit of selling this to anyone.. Am I alone in this?? HELP ME!!!
