A screen filter should be installed on every monitor screen. Computers are indeed a very effective and efficient tool to assist humans in completing various jobs, but behind all the benefits it provides, hidden health threats, especially to the eyes.
By using screen filters, most of the negative health effects of using computers for long periods of time can be reduced.
Know What is Screen Filter
A screen filter is a protective layer that is placed on the screen to reduce radiation, glare, and sometimes also to meet privacy needs. The benefits you can get depend on the type of screen filter you use. There are two popular types of screen filters, namely anti-glare and privacy filters.
1. Anti Glare
Anti glare (anti glare) is intended to reduce light reflections on the monitor screen as well as to protect users from exposure to radiation generated by the monitor.
All monitors emit radiation. Many parties, especially monitor vendors, claim that the radiation emitted by the monitor is so low that it does not endanger human health. However, there are also a number of studies that state that monitor radiation, even at low levels, is bad for health in the long term.
On an LCD monitor, the radiation level is not as bad as a CRT monitor, but the radiation is still there. In other words, the health risks have not been eliminated, only the level has decreased.
The radiation level of the monitor will decrease even more if you use a screen filter. This anti-radiation feature is an extra feature, while the main feature is to reduce reflections that appear on the screen due to less than ideal lighting conditions in the room.
2. Privacy Filter
Ever heard of the term visual hacking? The main purpose of a privacy filter is to overcome this type of hacking.
Visual hacking is a non-digital surveillance technique that is done by peering directly at the screen. As a solution, the privacy filter narrows the viewing angle on the screen. Thus, only users sitting in front of the screen can see the contents of the screen, while other people will not be able to see it from the right and left sides.
Although the main purpose is for security, the privacy filter also carries other features to prevent various eye health risks caused by the monitor (digital eye strain).
Health risks associated with these eyes include tired eyes, nearsightedness, farsightedness, red eyes, and others. Meanwhile, other health risks that are not related to the eyes but are still caused by staring at a computer screen for too long are headaches.
The negative impact of blue light emitted by the monitor screen can also be reduced by using a privacy filter. The impact is not only on the eyes, but also on human sleep patterns.
Privacy filters usually also have anti-glare features. Due to the completeness of its features, a screen filter that is included in the privacy filter category is more recommended than anti-glare.
