Clip-on Blue Blocking Eye Wear - Special Tinted Lenses Help You Sleep and Relax Your Eyes

Q: Can you specify the transmission of the glasses? Specifically do they remove transmission of light below 530nm? Thank you

Excellent question! They block 100% at 500nm and below , 99.2% at 510nm, 98.1% at 520, and 96% at 530nm

Q: Do these clip-ons also flip up?

In order to keep them as lightweight as possible, we opted not to use a flip up clip. Besides, once it's nighttime and you put them on you shouldn't be peaking anyways :-)

Q: What is the manufacturer's warranty in terms of the clip-on breaking from normal usage?

I don't believe I ever did notice a warrantee. They seem to be a pretty durable poly carbonate. They have some flex and very light. My take is that there's not much concern at all in dropping them or tossing them around. Of course if you stepped on them and crushed I would predict they may be a goner.

Q: Does it tint the computer screen? I need to know color accuracy when working on graphics.

Yes you certainly cannot block out all blue light without distorting colors. Blue and green will be indistinguishable and whites will look amber. You will get used to the color shift surprisingly fast but they are definitely not suitable for graphic design or other color sensitive work.
