Blue light screen protectors: do they work?
Your phone is 30 centimetres from your face for several hours a day. Your monitor, eight hours straight. The light goes straight from there to your eyes.
A blue light screen protector acts right at the source. But they don't all work the same. Here is how to tell them apart and which to choose for each device.
Quick answer
A blue light screen protector works if it has a layer that selectively filters high-energy blue light (380-500 nm) before it leaves the screen. Its advantage over glasses is that it always works, without you having to remember. Reticare has protectors for phones, tablets, laptops, monitors and TVs, developed with the UCM.
Do blue light screen protectors work?
Those with just a bluish tint or an "anti-blue light" tempered glass with no data do little. Those with a layer that selectively filters high-energy blue light (380-500 nm) reduce that light before it leaves the screen.
Reticare protectors use 4-layer technology developed from the research of the Complutense University of Madrid (UCM), with Dr. Celia Sánchez-Ramos and her team.

Screen protector or blue light glasses
- Protector: always on for that screen, ideal for children and a fixed workstation.
- Glasses: protect you on any screen and from LED lighting. Balance also filter green light (500-590 nm).
- Both: the most complete option if you spend many hours with screens.
Blue light protector for your computer: the most popular
If you work eight hours at a computer, the monitor is the screen you face the longest. The monitor protector and the laptop protector are the ones you notice most day to day.
Frequently asked questions
Do blue light screen protectors work?
It depends on the technology. Tempered glass with a bluish tint does little. A protector with a layer that selectively filters high-energy blue light (380-500 nm), like Reticare's, reduces that light before it leaves the screen.
Does a blue light protector change screen colours?
It may give a slightly warm tone. Reticare protectors are designed to keep the image sharp.
Which is better, a screen protector or blue light glasses?
The protector works only on that screen, without you having to remember. Glasses go with you to every screen. The most complete option is to combine both.
Is there a blue light protector for monitors and TVs?
Yes. Reticare has protectors for phones, tablets and iPads, laptops, monitors and TVs from 28 to 70 inches.
