I understand there are 2 ways a SP blocks the blue light:
1. Block it - those yellowish colour SP absorbs the blue light
2. Reflect it - those that does not absorb can reflect it so that it does not pass from the screen to the user's eyes.
However, I saw some of the anti-blue light SP are purplish colour. Does it actually work ? If it's purple (closed to blue colour), does it mean that it will pass the blue light instead of blocking it ?
Thanks.
