In today’s day and age, when computer usage and screen time have skyrocketed, our eyes need and deserve special protection. In fact, staring at digital screens has become so common in our lifestyle that it has become a part of us that we often forget the quantum impact they hold on our visual and sight health or overall well-being. 

However, when there is a problem, there is a solution, and talking about this problem, Blue-light blocking glasses got us covered. Blue light-blocking lenses prevent excess blue rays from reaching your eyes, and help dodge problems like eye strain and poor sleep cycles. However, the looming question is if blue ray frames really work or whether they are a marketing gimmick! Let us find out!

What are Blue Light Blocking Glasses?

Harmful ray-blocking glasses are highly advanced eyewear especially engineered to prevent harmful rays from entering your eyes. These products have a unique and advanced coating on the surface, which block or absorb any destructive rays emitted from digital screens.

The Working of Anti-blue Light Glasses 

These frames do work. However, the key is to remember that not all of them are the same. But, how can you figure out if your one works? Well, there is a way out!

While putting on the glasses, you should look at something that has harmful rays, such as the flashing rays atop a police car or ambulance. If you cannot see the blue lights flashing, then congratulations, the eyewear in your hand has good-quality filters. 

One of the best things about them is that blue lights are indeed not good for your eyes, therefore it makes no harm to you if you wear them throughout your day. But, it is important to be aware of a trick. These products framed with blue-tinted lenses make everything appear the same color, so the things or rays in that respective color will not be noticeable. 

Thus, it is best to opt for these products with orange, yellow, and amber lenses. ones with a clear lens block about 20% of blue rays, which might not be enough to restrict the harmful effects caused by excessive screen time. 

Is Blue Light from Digital Devices Really Bad for Eyes?

Now that we have cleared the air regarding their working, let us gauge how damaging these rays really are!

To begin with, they are simply one of the colors in the visible spectrum. In case you did not attend your school or are unaware of it, the visible spectrum is a family of long-wavelength red (700 nanometers) to short-wavelength violet (380 nanometers). All sources, from the sun to the digital screens of laptops and computers emit some high-energy rays. 

The most pertinent and common detriments of digital devices are eye strain and poor sleep cycle. When we stare for too long at a laptop or computer screen, we often forget to blink. The result is that tear ducts may either dry up or offer excessive lubrication, culminating in dry eyes or watery eyes. 

Similar blue light is also related to a skewed sleep pattern. The natural rays from the sun regulate our circadian rhythm and assist us in not falling asleep like a bear and carrying out our daily chores. But, when we are exposed to too much glare at night or after the sun sets, our circadian rhythm is disturbed, resulting in a lack of sleep and other similar problems which ultimately makes us sleep like a bear.

Final Thoughts 

In a nutshell, anti-blue light glasses do work. Although they might not be foolproof or offer 100 percent protection against the rays emitted from digital devices, they do offer a decent amount of protection and are excellent to prevent dry eyes or watery eyes. Besides, they might also help in maintaining a good sleep cycle. But, the key is to invest in the right pair of blue light-blocking glasses frames.
