No. And it might help to have someone with a background in science and optics answering this instead of folks repeating random stuff they were told in sales pitches at the sunglass shop. All tinted lenses will diminish the amount of light reaching the eye, blue and otherwise. Blue lenses would simply allow some more blue light through- no more than wearing clear lenses, or no lenses whatsoever. The biggest negative effect of a blue lens would come in situations involving depth perception- blue lenses will make the perimeter of objects appear "softer" and more out-of-focus, and as a result, can effect depth perception. Blue lenses will have zero factor in so called "blue light" or "HEV light" damaging the eye. There is also a growing body of evidence that the "blue light scare" has been blown out of proportion by lens manufacturers (most notably Essilor, a lens conglomerate that controls the majority of all prescription lens manufacturing in the world- yes, the world) in order to sell HEV "filters" that cost significantly more than standard anti-reflective lens treatments. While blue light can and will cause eyestrain and can effect circadian rhythms leading to sleep disturbance, it's looking more and more like it takes a greater amount of HEV to have these effects and that its long-term harm has been overexaggerated. TLDR: I have almost ten years experience in the optics field and a BS with a minor in biology. Blue sunglasses are not "bad" for you. I wouldn't drive with them though.
