    Blue blocker Dyes

    I noticed that the dye manufacturers such as bpi sell separate blue blocking dyes such as the bpi diamond 500/550. Are these just amber dyes, just that they cut off more accurately at the 500nm region

    Why can't we just use our existing dyes to match a similar transmission profile?

    Some filters and sunglasses tinted to orange with sufficient intensity have similar transmission spectrums. Blue blocker dyes seem to be orange dyes with perhaps a sharper cut off in the spectrum after 500nm?

    What would be the disadvantages of using normal orange dyes to replace blue blocker orange dyes? Unlike industrial customers, retail users will probably not require any specific cut off and will be satisfied a long as the lens blocks all blue light

    Very simple .................to make it work your way, is possible if you know what to do and when and how. It will be a totally different and long tinting process, that has been simplified by this one stage tinting process.

    Furthermore the finished and well working tinting job can now be tinted over into a dark amber, brown or even dark green, without changing the visible Blue Blocking qualities, but having a more pleasant appearance, and look cosmetically more pleasant.
