Since the innovation of computers, they have penetrated every aspect of our lives. Whether in the workplace, at home or at school, using a computer is now virtually mandatory. However, with this widespread continued use of computers, there’s a lot of concern regarding the effect on our eyesight. It’s now obvious that prolonged use of computers leads to a set of vision-related problems that are collectively known as Computer Vision Syndrome (CVS) or digital eye strain. This is why we need computer screen protectors for the eyes. In fact, just by spending more than 2 hours daily on a computer, you have a 90% chance of developing CVS. It goes without saying that most of us have experienced at least some symptoms of CVS. Such symptoms include eye fatigue, headaches, dry eyes, blurred vision, neck pain and many others.
In addition to causing CVS, computers are also notorious emitters of blue light. While blue light does have a role to play in the development of CVS, that’s not the full extent of the harm it can cause. Blue light has also been implicated in a number of other health problems. Excessive blue light from the sun and screens for example can cause damage to your eyes and may play a role in the development of age-related macular degeneration (AMD). It also suppresses sleep and can cause insomnia as well as disrupt your circadian rhythm. Protecting your eyes is therefore paramount whenever you are using computers. One of the ways to do this is by using computer screen protectors.
Anti-glare screen protectors
Glare coming from light-coloured painted walls, shiny surfaces and reflections on the computer screen are primary causes of eye strain. Glare results from a situation where a high level of contrast exists between the intensity of light in the foreground and background of your field of vision. While glare is present, your eyes have to work extra hard since they constantly adapt to the differences in contrast while looking at the content on the computer screen. Reflections on the screen of the computer also continuously distract your eyes and force you to exert additional effort to focus. This eventually leads to eyestrain.
If you aren’t keen on repainting your walls to a darker, less reflective colour, then finding an anti-glare screen protector is your best option. They have layers of anti-reflective (AR) coatings that eliminate nearly all the light that’s reflected from the screen into your eyes. Consequently, you don’t have to worry about reflections on the screen that will strain your eyes. There are many types of anti-glare screen protectors for computers, ranging from the bulky hang off the monitor type to thin films that you stick on the computer screen. What you select depends on the monitor style and your personal preference.
Blue light blocking screen protectors
Screen protectors can also come in handy for filtering out the blue light emitted by computers. Blue light has a shorter wavelength and contains more energy than the other components of the visible light spectrum. As a result, blue light penetrates deeper into the eye and causes damage. It also has a tendency to scatter while in the eye hence interfering with our visual clarity. Due to the fact that sharp vision is needed when performing computer-based activities, this interference by blue light may lead to eye strain.
You can prevent this and other harmful effects of blue light by acquiring a blue light filtering screen protector for your computer. The amount of blue light filtered out depends on a number of factors including the tint colour of the screen protector and the presence of a blue-blocking coating or other materials in the filter. The trick to the use of these blue light filters is finding a balance between the amount of blue light filtered and the colour distortion caused by the filter itself. Too much visual distortion can exacerbate the eye strain instead of solving the problem.

Conclusion To Computer Screen Protectors For The Eyes
While using computer screen protectors to safeguard your eyes is effective, don’t simply rely on this method alone. There are blue blocking glasses and computer software that will also block blue light from reaching your eyes. As for combatting CVS and eyestrain, there is a myriad of methods that can be used together to prevent or reduce the symptoms associated with this problem. For instance, even after setting up your anti-glare screen protector, try to blink more often and follow the 20-20-20 rule. That’s where you look away from your screen every 20 minutes to look at something 20 feet away for at least 20 seconds.
