Finest to go for darker tinted lenses (suppose amber, orange, or perhaps a deep purple) to utterly block out the blue gentle. That’s to not say clear lenses don’t assist in any respect, however in the event you actually need to up the ante, you may need to put money into a pair of ambers.
If you happen to do already personal a set of clear lenses, although, Banik does provide one other trick to inform whether or not the glasses truly do their job effectively: “Put them on, then take a look at your display at one thing that is blue. If you happen to can nonetheless see that coloration blue, it implies that it is probably not blocking the blue gentle.” On the flip aspect, if blue tones in your display have an orangey hue, this implies the lenses successfully omit the wavelength.
