I'm sceptical that blue light lenses, even those that effectively block blue light, are doing much of anything. Blue light can mess with your circadian rhythm, but so can orange-tinted light if it's bright enough. A better system would be to limit screen time after dark. If you are using screens, lower their brightness to the lowest amount you can still see. You can use a night -time filter to tint the screen orange after dark (most OS's and devices support some form of this). Blue light lenses while holding a OLED device six inches from your face at full intensity? Likely not doing much.
