Is Blue Light Really Harmful? What Science Actually Says

Nowadays, spending time on screens is just a fact of life. Focusing on your laptop work, gaming, or watching anything on a screen means you’re seeing blue light. Yet, the main issue is whether blue light is unsafe, as some claim, or just a myth.

I’m going to cover why blue light is bad for your eyes, how it has an impact on your health, and how you can minimize this risk with a few simple changes.

What does the term Blue Light mean?

Spectral gaze stimulated by cell phones and computer screens is defined as blue light, since it runs between 400 and 495 nanometers. Smartphones, tablets, and computer monitors also produce this type of light, just like the sun.

During the day, blue light improves our sleep, though being exposed to too much at night might result in difficulty sleeping, trouble with our eyes, and even cause vision damage.

Is Blue Light Indeed Bad for Our Eyes?

Scientists have looked into how blue light affects people’s health, and the results are considered well-balanced:

• Digital Eye Strain (DES): Exposure to blue light is only one reason eyes become overworked. Being on a screen for long periods reduces the number of times we blink, which leads to dry and uncomfortable eyes.
• Disturbed Sleep: Producing melatonin is hindered when your eyes are exposed to blue light at night.
• Retinal claims: These are based on studies showing blue light could impact eyes in animals, though there is not enough reliable evidence for such issues in humans.

Recommendations From the Experts

According to ophthalmologists, people should take breaks by viewing something that’s 20 feet away for 20 seconds every 20 minutes. Choosing a screen that helps reduce eye strain by being gentle on the eyes is a benefit.

Monitors that Have Low Blue Light Technology

If you don’t stay in one place often and mainly work away from an office, using a portable gaming monitor that has eye care features could be very useful. They are built to ensure your eyes are protected as you use them for long periods.

For example, check out this 18-inch 144Hz FreeSync portable monitor. The monitor was designed for those who enjoy bright graphics, but are also conscious of their health. Applying Low Blue Light Mode and Flicker-Free ensures your eyes do not get strained as much when you work or play video games for extended periods.

Touch Screen Monitors are Eye-Friendly Too

When it comes to reducing stress on our eyes from screens, being comfortable is very important. An often forgotten answer to this problem is touching the screen on your monitor.

Because of these displays, users find it easier to control things with the controller alone. 

A touch screen monitor is made with anti-glare finishes, allows for high brightness levels, and features blue light filters, too.

How is Vision Impacted by Display Screens?

Some screens are better than others. Consider the following features when purchasing a monitor for your eyes:

1. Low Blue Light Technology: Filters away harmful blue light.
2. No Screen Flicker: The TV doesn’t flicker as much, which can help reduce tiredness in the eyes.

Fortunately, most portable monitors now come with at least one of these special features. If you use a monitor every day for work or just for fun, selecting the correct device may save your vision.

How to Lessen Your Exposure to Blue Light

Other than picking the correct monitor, there are a few short tips you can keep in mind.

• Try Night or Eye Comfort Mode: If yours does not have it, you can install a Blue Light Filter App.
• Get some Blue Light Glasses: These are designed to block harmful visible light.
• Avoid watching TV or using phones an hour before you go to bed.

Conclusion 

There are many gray areas in this subject. Even though there isn’t much to worry about with screens, being vigilant never hurts. Opting for an eye-friendly monitor, for example, you can buy a portable or touch screen model, which largely prevents the development of health problems.

In other words, keep using technology as before, but upgrade it carefully. Robust portable monitors have become essential because they are so helpful to our well-being.
