How do I test PC glasses to see whether they can block blue light or not?

Our eyes are an incredible wonder: think about all the beautiful sights we encounter every day. Thanks to our eyes, we can read people’s body language, write, drive, and, of course, use the various screens that we love so much.
How could our eyes perceive so much, you might ask? The eye is exposed daily to different electromagnetic waves, such as UV light. It can only perceive the waves that are a part of the visible portion of the electromagnetic spectrum: the waves break through our eye’s natural protection and reach the retina.
Afterward, our eyes transfer this information to our brain, which interprets it into an actual image. Although the process takes nano-seconds to occur, it’s incredible to realize that our eyes transmit so much information to our brains every day. That’s why it’s vital to care for them and protect them from harmful waves, like UV light and blue light; later in the article, we will explain how you can protect your eyes, thanks to an efficient blue light filter.

What is Blue Light?

Blue light comes off the sun and any screen we use, including the TV, the computer, and even our beloved smartphone. It makes your eyes tired over time because it damages your sleeping patterns.

Studies show that we need blue light in our lives because it helps regulate our waking and sleeping patterns: the blue light helps our bodies understand when it’s daytime, and we need to be alert. When it’s not transmitted to our eyes, our bodies realize that it’s night time and high time to go to sleep.
When our eyes perceive blue light through the sun alone, our sleeping patterns are legally ordered. However, nowadays, our eyes absorb so much blue light from the different screens we use that it burdens our eyes and impairs our sleeping patterns.
Due to overexposure, blue light could make us stay awake and prevent our eyes from the rest that they so desperately need. Consequently, our retina could be harmed, and the risk of suffering from macular degeneration could become quite real.

So, is Blue Light Bad?

Not at all. We all need blue light every day, but in moderation, just like anything else in life. As long as we take the right precautions, we can easily enjoy the blue light’s benefits and avoid its cons. 

If we prevent our eyes from absorbing blue light during the night time, it will help our bodies realize that we need to rest and encourage us to sleep. Subsequently, our eyes will not perceive too much blue light and will also take pleasure in a much-needed rest.

If you happen to suffer from headaches, sore or tired eyes, or stiff necks, you should start caring for your eyes.

Blue Light Filtering Glasses

Blue light filtering glasses help us care for our eyes in the best way possible: they block the blue light, just like sunglasses block harmful UV light. They’re scientifically designed to feel just like any ordinary glasses. Still, They have a unique coating within the lenses, which allows all visible light wavelengths to pass through, except the most harmful ones.

The lens’s quality changes from brand to brand, so most glasses will block different blue light degrees, varying from 10% to over 90%. If you want to protect your eyes and enjoy the benefits of blue light filtering glasses, you should look for ones that block at least 50% of blue light.
