Q: Will these also block the flickering from flourescent lights!
submitted by LJP - 4 years ago
A: LJP, I wish I could say they do, but the flickering in flourescent bulbs isn't a blue light issue. Flickering in flourescent lights comes from the inevitable decline in the particular bulbs ballast which is the method the moderates the even flow of light in the bulb. If you can switch the bulb it will solve the problem...at least until it happens again. Good luck.
