Whether you want to wear sunglasses that block out the blue light from the sun or you want to wear glasses that have filters to block out the blue light from digital screens, you may be wondering if it’s good for your eyes to wear these glasses. These glasses help you sleep better, reduce the glare from digital screens, and reduce the symptoms of digital eye strain.
Improves Sleep
Better sleep is an essential skill that can enhance your leadership and business. You’re likely to make good decisions with a good night’s sleep. Conversely, a lack of sleep can hurt your relationships and work, affecting your behavior and productivity.
Some people wearing blue light glasses before bed improved their sleep. These glasses work by blocking the light of blue wavelengths. Blue wavelengths are believed to affect sleep by suppressing the production of melatonin, a hormone that regulates sleep.
Blue light can also disrupt your body’s internal clock, making it harder to fall asleep. In addition, blue light can also reduce your energy during the morning. The light of blue wavelengths can also disrupt your work habits, which may lead to poor productivity.
One study by Chronobiology International found that blue light filters could improve sleep. The study, which included 63 managers, measured task performance, sleep duration, and sleep quality. The results showed that blue light-filtering glasses increased sleep duration, improved sleep quality, and reduced sleep onset latency.
Another study in the Journal of Lighting Research and Technology found that blue light glasses can help teenagers avoid melatonin suppression. These glasses work by inhibiting the synthesis of melanopsin, a hormone that suppresses melatonin. Melatonin has been shown to help you fall asleep, but it takes a while to start working again after it’s hidden by light.
Reduces Glare
Using blue light glasses is an excellent way to reduce glare. Try these glasses if you frequently sit in front of a screen for extended periods. They’re also recommended if you work in a bright, LED-lit environment.
Blue light glasses are made from a special coating on the lens that blocks blue light. The layer is also anti-reflective, which is designed to reduce glare. In addition, the coating can help increase the quality of your sleep and reduce your eye strain.
Studies have shown that blue light can cause several eye problems, including glare, dry eyes, and blurred vision. In addition, some studies indicate that blue light can disrupt your body’s natural circadian rhythm. These symptoms can make it hard to sleep.
Although the effects of blue light are still not well understood, blue light glasses may help to relieve the symptoms. Blue light glasses can also help reduce the impact of oncoming headlights and streetlights on your eyes.
One study found that blue light glasses reduced eye fatigue. The glasses also helped to improve the quality of sleep. The study looked at people who had symptoms of computer vision syndrome. This condition occurs when you spend a lot of time looking at a digital screen.
Helps With Digital Eyestrain
Using blue light glasses is a popular way to alleviate digital eyestrain. However, the science behind this needs to be clarified, and there needs to be more data to prove that blue light glasses actually work.
Developing good screen habits is the best way to find relief. In addition, regular breaks and proper seating posture can reduce eye strain.
Another practical approach is to use blue light filtering glasses. These are designed to block blue light and allow other wavelengths through. They also help you to reduce screen time.
A small study in 2017 found that blue light glasses did increase sleep quality. However, the effect was modest, and further research is needed.
If you use blue light glasses, you should talk to an optometrist to see if there are any other visual health issues you need to address. An optometric team can also provide recommendations for visual aids and devices that can help you see better.
Another effective way to reduce digital eyestrain is to wear anti-glare screens. These will decrease glare and lessen the brightness of the screen. Also, choose a pair of ergonomic accessories that help improve your sitting posture.
Are They Harmful?
Several popular eyewear companies are touting their blue light glasses as a way to protect your eyes. They claim that their glasses will reduce eye strain, headaches, and other problems associated with screen time. However, blue light’s impact on your eyes needs to be studied further, as existing research needs to be more conclusive.
The sun produces blue light, passing through the cornea and lens. The damage to your eyes depends on the wavelength of the blue light and how long you are exposed to it. Several studies have found that blue light can cause damage to the retina, which is the thin tissue at the back of your eye.
Blue light can also disrupt the body’s melatonin production, affecting sleep patterns. This can lead to permanent vision changes.
Blue light also hurts depth perception and peripheral vision. For this reason, you should sit at least 25 inches away from your computer or another electronic device. You should also set your device to night mode. It would help if you took frequent breaks from screen use to avoid eyestrain.
