All those people who spend many hours in front of a computer should try to take care of their eyes as much as possible, since that continuous exposure can cause visual fatigue, headaches or other types of alterations. A good solution is to place a screen protector on our device to protect our eyesight.
These types of protectors are very efficient in taking care of the eyes , but they can also have another facet just as interesting. Several of them not only limit the exposure of our eyes to blue light, but also limit the visibility of others and only allow us to see the screen clearly.
This means that if someone stands next to you and tries to see your laptop screen, they won’t be able to gossip about what you’re doing. This type of protector is called security or privacy .
What exactly is blue light?
Light is a set of visible radiation that is located between 380 nm (blue-violet) and 750 nm (red). Everything that is above or below is radiation not visible to the human eye.
Blue light itself is necessary to see colors and is between 380 nm and 475 nm. Even when we see white light, it is not really like that, because it has 25% blue light, even if we do not notice it.
This type of light is necessary, but the problem comes when we are exposed to it for a long time .
The most damaging part of this type of light is UV , which is the cause of fatigue and visual stress in the short term, although there is some study that assures that this blue-violet light can cause cataracts in the long term. That is why we must take care of ourselves and protect our eyesight in the present and in the future.
Types of protectors
As we have told you lines above, the main task of protectors is to protect our eyes . But there are also those known as security types , which are responsible for safeguarding our privacy.
Blue light protectors
These types of protectors are filters that ensure that blue light does not come out of the screen , absorbing all those waves that are harmful. Thanks to this we get a great protection of our sight.
Security filters
Some protectors, in addition to controlling the exposure of our eyes to harmful waves, also have a system so that everyone who is not at a right angle of vision to the screen, sees it in black .
They do this thanks to a polarized plastic sheet that acts as an optical filter that blocks light at certain angles.
