Blue light

I was wondering which of these polarized lenses by oakley cuts out the most blue light: gold iridium, bronze, amber iridium, and fire iridium. Whenever I talk to the oakley sales people in the store or by phone they always say that all their lenses block 100 percent of blue light and 100 percent of UV light. The UV light I can beleive, but can a grey lense really block 100% of blue light. And I thought that it was undesirable to block 100% or blue light (from what I've read it can be danngerous to use driving). I am going to be using these glasses mainly for fishing.

As far as I know Oakley's blue light protection is build into the lens material during manufacturing and the lens color does not affect the blue light blocker. Even Oakley eyeglasses made with authentic Oakley Rx clear lenses have this feature. Oakley is not the only brand that offers blue-light blocking lenses in other than amber/brown color. Serengeti is a good example. All their lenses including 555nm which is dark green block blue light.

That is cool yet very strange. I always thought that the blue light reduction was caused by the lens color itself (for example when wearing amber lenses you can't see blue color very well and when you take them off everything looks extremely blue). Do things appear more yellowish or amber when looking through these blue blocking lenses, even when the lenses are grey?
So if I bought grey lenses, (which usually have low color distortion) will I have high color distortion because they are Oakley blue blocking lenses? I actually don't mind some color distortion I was just wondering how the blue blocking works. I heard from various places online, that if you can see the color, it is not being filtered, which makes sense.

Some lens colors like yellow, brown and amber naturally tend to reduce blue and improve contrast. But tint is usually a coating that is applied on top of the lens. Usually that's a thin surface film that can become easily scratched. In addition to natural lens color properties brands like Oakley and Serengeti offer sophisticated technology. That's why they cost a lot , but people will still buy them.
