These Screen Protectors Reduce the Bluelight Coming Out of Your Kindle’s Screen
The Kobo Aura One and many reading apps offer a night reading mode which help readers by reducing the amount of sleep-disturbing blue light emitted from the screen.
And now there’s a solution for your Kindle.
A discussion on MobileRead has tipped me to a new category of screen protectors which the manufacturers say are designed to filter UV and blue light on the Kindle.
From the product description:
- This kit features 2x Blue Light screen protectors for Amazon Kindle Paperwhite (3G,2012,2013) along with a set of instructions, installation squeegee, microfiber cleaning cloth and the iLLumiShield lifetime warranty.
- Designed with High Quality PET film imported from Japan that consists of multiple layers. Each layer provides specific functions that allow the Matte Anti-Glare line of Amazon Kindle Paperwhite screen protectors to outperform competitor products that use inferior materials and manufacturing processes.
- Blue Light technology deflects harmful blue-violet light & UV away from your eyes while allowing beneficial light to pass through.
The screen protectors cost $11 on Amazon.com and 25 euros on Amazon.de (they’re from different companies). That is a fair price to pay for a better night’s rest – if the screen protectors work as promised.
In the case of the screen protectors sold on Amazon.com, they might not. That listing has a bunch of reviews from dissatisfied customers who report that the screen protector merely made the Kindle’s screen shiny but did not block or reduce the blue light.
Of course, there were other reviews which said that it did work, so it is impossible to say whether the screen protector works. Really, the only way to know for sure is to buy one, apply it, and see if it changes the Kindle’s frontlight to a red-orange color (this is what is left after removing the blue frequencies from a while light).
If you get one, please let us know. We’d all like to know if this works.

I used to have screen protectors on my smartphone, and I always get bubbles after I installed them. I can’t deal with looking at bubbles.
If someone wants to block blue light, it seems better to wear blue light filtering glasses, since filtering the blue light changes colors you may not always want to see the lack of blue.

I use the Kindle or Kobo or Nook until it gets dark then I switch to the iPad Mini with the night shift mode to read at night. This works very well and when I don’t use it and continue to use the e-ink readers I do see a difference in my ability to fall asleep. Amazon night mode on the Fire tablets is a complete joke compared to Apple’s night shift.

But the Paperwhite and other Kindle models are all front-lit LEDs that point down at e-ink screens, so there’s no backlight shooting through an LCD. As I understood it and have experienced it, using nightshift mode on my iPad Air 2 at night is much better than non-nightshift mode but still not quite as good for the eyes and sleep as reading on a low-light setting on my Paperwhite.
Further, I don’t see how a screen protector could filter light on a Paperwhite. The screen isn’t where the light comes from, so all you’re doing is putting a blue filter on an e-ink screen the device is shining LED lights onto, anyway. Because the light comes from around the frame in a Paperwhite, you’d need a frame-based filter, not a screen protector with a filter, wouldn’t you?

The LEDs shine their light into a diffuser which spreads it across the screen, shining the light into your eyes. The screen protector lies on top of the diffuser, so yes it theoretically could filter out the blue light.
All it would take is a reddish-orange film on top of the diffuser.

Some time in 2017 Kobo started making e-ink readers (Kobo Aura One, Kobo Aura H2O Edition 2) where you can adjust the hue of the front-lights. So you can have both reflected light and get rid of the blue tones. As far as I know these are the only two readers (for now) that solve both problems.

Personally, I sit in front of 4 23″ monitors blasting blue light to me all day and well into the night. I sleep fine.
I like the Aura One’s ability to change the background from white to gray to beige but as far as health benefits? No.
