Does this shield block blue light?

Evelyn Belinda Willis, thanks for your question. For the iPad 2/3/4 we do not have a RetinaShield screen protector to protect from blue light. So, no this screen protector does not block the blue light. Best, Tech Armor Support

Some matter of fact...no ... a very dim blue light is visible... Not intrusive at all...

No, only when you press the button to illuminate it. When you release the button, the blue light goes off.

This is not a technically documented answer. They block significant amount of light. Essentially they remove more the half of the annoying glare light when driving, including from the old lights and the new blue eye killers.

Yes, if I recall correctly, I believe the blue light ring can be turned off. I'm pretty sure about that.

Yes. The light toggles through various colors and gives the option to have no light.

Yes, we have noticed that if it is not detected any device then the device turn the led light red, In the opposite way the led will show a blue light when a device is connected. We are very satisfied with this purchase.

It blocks up to 540nm light and the specification for the specific tint says that it blocks greater than 98% blue light. See page 14 of http://www.uvex.us/uploadedFiles/ProductConfiguration/ProductLiterature/Uvex_Lens_Tech_Update2011.pdf

The display light which is quite bright goes on automatically when you press buttons and it goes off after a few seconds of not touching anything. There is a small blue bulb light that stays on all the time but I haven't found it to be disruptive. In a dark room it will give off a bit of a blue glow and I suppose if it really bothers you can try to cover it up but as I say, it hasn't been an issue for us.

Not sure if your asking a question or making a statement but it does prevent a little bit of the blue LED ....but it doesn't seems to work well with cyan LED light blue...

Yes, it should be illuminated in blue. It sounds like the backlight on your's may be broken.

I haven't noticed a blue tint to the lighting. So I would have to say no. I really like the device. I frequently use it for illuminating whatever I am working on without any magnification, but if I need magnification, I have that as well..

Yes. It completely blocks out the light.I hang it in front of my garage window.

Yes, there is a light blue light in front below the lens. You can also hear a faint sound when it works.

It depends if you put a single row or double light bar. If you do a double it's gonna block a lot
