Can anyone clarify with me whether or not we can use a blue light blocking filter or coating on lenses for dentists and dental hygienists? They seem like the type who would need it the most but I've heard conflicting things. I've heard some people say that the blue light filter interferes with their work and I've heard others say that they should have it because of the amount of blue light they have to look at each day. Can anyone clarify this? Thanks!
