With the constant development of technology, there has been a high rise in visual devices whether it be a compact mobile, an advanced monitor, VR, or more. These advancements proved to be a bane for the world, but it also had its fair share of downfalls. 

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 issues like eye strain and poor sleep cycles. However, the looming question is if blue ray protection frames really work or whether they are just 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 of the lenses, which blocks or absorbs any destructive rays emitted from digital screens.

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 we often forget the quantum impact they hold on our visual and sight health or overall well-being. These lenses were invented to lessen the impact of harmful rays that might affect our eyes, causing eye strain, loss of sight, and more. 

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 powerful rays, such as the flashing lights 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 they do 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. Glasses with a clear lens block only 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 Awful 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 of light, from the sun to the digital screens of laptops and computers emit some high-energy rays. And when in direct contact, these can be proven as harmful.

Screen time for a long period causes eye strain

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. 

Similarly, 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.

Prevention Measures to Decrease the Impact of Blue Rays

Since the era of the pandemic, there has been a rise in the usage of digital devices. An increase in screen time has been reported to cause an alarming rise in the ratio of the population with visual impairment. According to a report in 2021 by WHO, over 2.2 billion of the world’s population have near or distant vision deterioration. And although there are various factors that affect eye health, phone, and computer screens has been the major cause.

Tips to prevent eye strain

As per eye experts, one should not have a continuous screen time of 8 hours and above. And if that’s really necessary and a part of your daily routine, then it’s better to take precautions as to damage your eyesight. 

  • You can take periodic breaks while working and look away from the screen for a few minutes. 
  • Try to use devices with bigger screens to relax the muscles of convergence in your eyes. 
  • Another amazing option would be wearing blue light-blocking glasses to reduce eye strain while working with computer or mobile screens. 

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 for preventing dry eyes or watery eyes. Besides, they might also help in maintaining a good sleep cycle.
