Blue light-blocking glasses may be the answer if you are looking for an effective way to combat digital eyestrain. They are also a convenient option to prevent eye fatigue, dry eyes, and headaches while you work on your computer or use your devices.
Although your cornea and eye lens are good at blocking harmful UV light, they do not block the shortwave blue light emitted by digital screens. This can cause several eye diseases, including macular degeneration and cataracts.
Reduces Eye Strain
If you’re looking for a solution to the eye strain you feel after spending hours in front of your screen, blue light blocking glasses could be the answer. However, before you shell out for a pair of glasses, it’s essential to understand how they work and whether or not they improve your vision.
According to a February 2021 study published in the American Journal of Ophthalmology, blue-blocking glasses may not do anything to alleviate digital eye strain symptoms. Instead, they may make it worse.
Similarly, another small study published in Optometry and Vision Science in January 2019 found that a filter that blocked 99 percent of wavelengths between 400 and 500 nanometers did nothing to relieve eye strain or other computer-related problems.
Fortunately, plenty of options on the market can help reduce eye strain and improve sleep quality. Some of the most popular models include Teen Blue Light Glasses, which protect your eyes from a wide range of blue-light wavelengths while still allowing exposure to melatonin-boosting blue light in the evening.
Relieves Eye Dryness
Whether you are watching TV, using your smartphone or laptop, or playing video games, exposure to blue light can cause eye fatigue and discomfort. It can also lead to dry eyes and headaches.
There are many ways to minimize your screen time and protect your eyes. One of the most effective is to use blue light blocking glasses.
These glasses are designed to filter the blue light from your screens and other LED lights, as well as the sun’s harmful UV rays. They also help to reduce glare.
You can choose from a variety of different styles, including ones that have yellow-tinted lenses. These are often more comfortable to wear and offer a higher level of protection against blue light.
Although there isn’t much evidence that blue-light-blocking glasses prevent digital eye strain, they may help reduce or alleviate tired eyes’ symptoms after prolonged usage. They can also help you sleep better by reducing the amount of blue light in your environment.
It Helps You Sleep Better
Blue light is a part of the natural spectrum of sunlight and other visible lights, but it also comes from screens, fluorescent lighting, and other artificial sources. Too much exposure to these light sources before bedtime can disrupt your circadian rhythm, leading to insomnia and other sleep disorders.
Studies have shown that wearing blue light blocking glasses improves sleep. These glasses block a portion of the blue light that suppresses melatonin, a hormone that promotes sleep.
These glasses are designed to block wavelengths between 400 and 450 nanometers, the range of blue light most likely to disrupt your sleep cycle. The lenses of some brands are tinted with amber or yellow-tinted filters, while others have a nearly clear coating or incorporate blue light blocking technology into the lens itself.
A properly fitting pair of blue light blocking glasses shouldn’t pinch or squeeze your face and should fit comfortably around your head. You should also be able to move your glasses from side to side without having them fall off or putting pressure on your ears or nose.
Boosts Your Mood
A small amount of natural blue light emitted by the sun helps regulate our circadian rhythm -the body’s natural wake and sleep cycle. It boosts alertness, memory and cognitive function, and mood.
However, too much exposure to artificial blue light emitted from screens and in the evening can disrupt our circadian rhythm. It’s best to turn off your devices two hours before bedtime and take frequent breaks from screen time.
In the meantime, you can help your eyes and improve your sleep quality by wearing blue light blocking glasses at all times. They’re available in various colors and styles, so you can choose one that suits your personality.
While studies investigating the effects of blue light-blocking glasses on sleep are small, there’s some evidence that these glasses can improve sleep for individuals with insomnia undergoing cognitive behavioral therapy. However, these studies aren’t randomized, and there’s no proof that they prevent melatonin suppression.
It Helps You Use Your Devices Longer
If you spend a lot of time on your devices, you know that prolonged exposure to blue light can harm your eyes. This is a condition called digital eye strain, and wearing glasses that block this wavelength can help reduce your symptoms.
A study that examined 36 people who wore blue light-blocking glasses for two hours found that those who used the glasses experienced less eye strain, eye itching, and pain. However, the research is inconclusive, so talk to your doctor about this option if you are concerned about your eyestrain symptoms.
When looking for a pair of blue light blocking glasses, look for one that is comfortable to wear and has a generous trial period or return policy. Also, make sure you pick frames that fit well on your face so they don’t pinch the bridge of your nose or slide down your nose.
