What is a blue light filter?

For those who have spent too much time deep in the mountains of Assassin's Creed Valhalla, the blue light screen filters are physical films resembling protective "glasses" that you attach to your computer screen, your tablet or even your smartphone.


How it works ?

From one device to another, blue light filters for computers, tablets or smartphones always apply to the screen of your device. These filters are designed to absorb the harmful part of the light spectrum that damages your retina over the long term. It's a bit like a Star Wars-style electromagnetic shield, but for your pupils!

Before you return to the snowy forests of Norway, we have listed the advantages and disadvantages of this protective device.

The pros and cons


Protect your eyes

The first advantage of a filter is obviously the considerable reduction of harmful blue light for our eyes in the long term . By reducing its impact and its intensity, our brain better assimilates the light, our eyes are less subject to the dangerousness of this light wave, so we guarantee better health for our pupils.

Screen filters can reduce this light by at least 80% , enough to protect your eyes when you play for many hours.

Another tip : A good diet is also a preferred solution to improve your eyesight and protect it . Our article on this can be viewed here .

be less tired 

Protection filters also have the particularity of lowering your energy bar a little more slowly. Indeed, the reduction of blue light makes it possible to avoid too much disruption of your biological clock , you will sleep better and will therefore be more efficient.

A better balanced brain

We won't guarantee you to have the same power of concentration as Magneto, but better protected eyes and a less tired brain will also allow you to be more efficient and better concentrated.

By reducing the level of blue light using a filter, our brain regains a less disturbed day/night rhythm . Therefore, it will also influence your internal clock and allow you to have a more balanced and healthier sleep pattern.

Another tip : The best thing will still be to avoid exposure to screens one hour before going to bed!

Avoid eye pathologies

Blue light has harmful effects for the eyes (dry eyes, blurred vision, etc.). Thanks to its protective technology, the filters will delay or even prevent certain eye diseases such as AMD ( age-related macular degeneration which accelerates with blue light ) or even cataracts.

The lessers

Changing colors

    Filters very often use the color yellow to attenuate the radiation of blue light. This logically alters the quality of the colors on the screen . Instead of accurately viewing the wonderful graphics of a game like Genshin Impact, they will pull the colors a little yellow, like a good old photo of your great aunt Monique.


    Not 100% effective

    If you were looking for a 100% effective filter, you could be significantly disappointed. PC blue light filters do not completely stop the transmission of this harmful light wave. Indeed, despite technological progress, filters are not yet capable of absorbing all of the light ray released by our screens.

    In addition to this, recent studies conducted by the University of Manchester suggest that our eyes react as much to other colors as to the blue light coming from our screens.


    So, the best thing is probably to combine the solutions or find other alternatives to adorn your eyeballs with additional defense points.

    Recommendations and alternatives


    From one individual to another, preferences and expectations may be different. At Horus X we will always be on the side of protection and prevention when it comes to the health of your eyes .

    We consider this solution of blue light filters with great interest and seriousness. We believe that its use can indeed be an interesting solution to compensate for the significant exposure of blue light .

    We nevertheless prefer other alternatives, which seem less restrictive and probably more relevant for a high-level player.
