Until then, blasting cultured rat cells in petri dishes with high powered LASER energy is hardly a scientific basis on which to assert broad claims of "danger" for the public, and then rush to market "solution" lenses. But hey! It's all ok if you make lots of bucks, right?
It seems almost anyone can be bought for the promise of an easy dollar. Yes, even in our industry. I've attended many many many "master" optician CE courses over the years, as have many here. And sadly, the designation is no guarantee of the quality of material presented, as I know others have experienced as well. In the end, if researchers are going to move forward with the study of "dangerous light" let them get on with it already. Regardless however I don't expect we will see any great reduction in the blue light fad/craze anytime in the immediate future. More's the pity.
