In today’s world where everyone, social media, is lighting up our screens with exciting new information, it can be hard to close your eyes and fall asleep.

You know how it goes. You lie in bed with a tablet, vowing to read only one chapter of the book. But in an instant, you’re Google your ex to find out who he’s currently dating, read the latest news, watch recipe videos, and look for a great takeaway restaurant in your area. By the time you finally turn off your tablet, your eyes and brain will be too aroused to sleep.

But why is screen radiation at night such a hindrance to sleep? The answer lies in the very light of your device. The screens of most electronic devices are made using Light Emitting Diode (LED) technology, which produces blue light. Although blue light is all around us – the sun is the biggest source – it becomes a problem when we get too much of it before bed.

Goggles that block blue light come to the rescue. Also referred to as blue light filtering glasses, these goggles have specially designed lenses that reduce blue light and allow the rest of the light spectrum to pass through.

We know what you’re probably thinking: “Will wearing blue light blocking glasses allow me to use my tablet before bed and sleep soundly?”. Short answer: maybe. But not only glasses have magic against blue light.

Can Blue Light Blocking Glasses Benefit You? Let’s find out.

What are blue light blocking glasses?

When something produces light, different lights vibrate at different wavelengths. Ultraviolet light is called high-energy visible (HEV) light. This is exactly what is most reminiscent of the potential dangers of blue light emitted by the sun.

Naturally, artificial blue light is much weaker than the blue light emitted by the sun. Currently, many people spend most of their time indoors in front of digital screens, resulting in low levels of exposure.

It is not known whether blue light from electronic devices is directly related to eye problems, but it may be a contributing factor.

“ Adults have an average of 11 hours of device use and screen time per day, so our eyes experience more light exposure from digital devices,” said Dr. Sheri Rowen, ophthalmologist and member of the Vision Health Advisory Board. and eye protection.
According to Rowan, “the lenses help reduce digital eye strain and avoid jet lag that affects sleep and overall well-being.”

Blue light blocking glasses block a percentage (percentage) of that light with a special coating that deflects blue light away from your eyes. How high the proportion (in percentage) of such a block depends on the points you have purchased.

Some blue light blocking glasses have yellow lenses, while others are clear.

Generally, lenses that are more yellow in color can filter out more blue light than their clear counterparts.

“It’s best to first consult with an optometrist who can help you figure out if you need protection,” says Rowan.

Possible benefits of blue light blocking glasses

Our experience with modern technology is comparatively short, especially the habit of spending 11 hours a day staring at a screen.

We still don’t know much about how such use harms the health of our eyes.
Blue light blocking glasses often offer two potential benefits: eye strain relief and improved sleep.

“Whenever we use our digital devices, especially late at night, we are actually telling our brains to keep our bodies awake,” said Caroline Dubreuil, product marketing manager for EyeBuyDirect.

Dubreuil added: “Study results show that wearing blue-light-blocking glasses 3-4 hours before bed can help promote better and more restful sleep.”

How do glasses help with eye strain?

Blue light protection glasses are made to let the good blue-turquoise light through while keeping out the harmful blue-violet part of the spectrum. They are available with OTC and prescription lenses. Blue light protection glasses not only help relieve eye strain, dryness, and irritation, they can also improve the quality of your sleep—all in all, dream glasses!

Do you need blue light blocking glasses

This can help to approach the choice of blue light blocking glasses through trial and error.

If you have eye strain or trouble falling asleep (especially after an excessive amount of screen time), you may want to consider wearing blue light blocking glasses.
They may relieve some of the strain on your eyes or help you fall asleep a little faster, or maybe not. Some people believe that these glasses are of great benefit, while others see no benefit.

Therefore, you can try to buy such glasses and save your finances, even if they do not benefit you.

Formation of vision hygiene skills when working behind a screen

Whether you wear blue-light blocking glasses or not, you need to develop screen-safe eye health skills that will help relieve eye strain and the effects of computer vision syndrome.

Symptoms of digital eye strain often include blurred vision , headaches, and dry eyes. Eye strain that comes from working behind a screen can even trigger ocular migraines.

It’s easy to remember and use the 20-20-20 rule: After every 20 minutes of using the screen of a digital device, look at an object that is 20 feet (about 6 meters) away from you for 20 seconds.

Adjusting to a new lifestyle, such as regularly applying the 20-20-20 rule, taking long breaks from screen work, and using dark mode on your phone, can bring additional benefits along with blue light blocking glasses.
