The COVID-19 pandemic has benefited the blue light glass industry.
Definitive evidence that eyeglasses actually reduce eye strain and protect against the effects of blue light as blocked people spend more time looking at laptops and other digital screens. No, but they are ordering more blue light glasses.
According to The Business of Fashion, eyewear company Book Club said that sales of blue light eyewear in March and April 2020 increased by 116% from the same period in 2019 and are increasing continuously.
“We can never predict that a time like [a pandemic] will be a time when a brand will suddenly thrive, be sold and get a lot of attention,” said Creative Director Hamish Tame.
Research firm 360 Research Reports claims that the global blue light glasses market will grow from $ 19 million in 2020 to $ 28 million by 2024. Promoted benefits of eyeglasses include reducing eye strain, improving sleep, and preventing eye diseases.
In the UK, a university of vision measurement scholars said: “The best scientific evidence currently available supports the use of anti-blue eyewear in the general population to improve vision, relieve symptoms of eye strain and discomfort, improve sleep, or maintain quality. Not to keep the yellow spots healthy.
However, some ophthalmologists believe there are benefits.
Greg Rogers, Senior Optician at Eyeworks in Decatur, Georgia, says he saw the benefits of blue eyeglasses among store customers. The staff asks the customer how much time they spend each day in front of the screen. If it takes more than 6 hours, we recommend some kind of blue light reduction technology, either glasses or a special screen for computer screens.
The Vision Council, which represents the optics industry, does not promote individual brands or products, but “everyone does their own research, talks to opticians, and finds the right solution for him and his family. Encourage you to find. ”
Blue light is everywhere
Before the beginning of modern digital life, there was a lot of blue light. Most of them come from the sun. However, devices such as televisions, smartphones, laptops, and tablets that live in modern life emit brighter, shorter waves (bluish) light.
And for a pandemic, Vision Direct, which surveyed 2,000 adults in the United States and another 2,000 in the United Kingdom, is considering these devices further.

According to a study published in June 2020, these adults spent an average of 4 hours and 54 minutes on their laptops before and after 5 hours and 10 minutes. They spent 4 hours and 33 minutes on their smartphones before and after 5 hours and 2 minutes. The screen time when watching TV or games has also increased.
Susan Primo OD, an ophthalmologist and professor of ophthalmology at Emory University, agrees that previous studies have shown that abuse of digital rather than blue light causes eye problems. However, some patients wearing blue glasses report less eye strain, she says.
Trying to sleep
Another argument in favor of blue light glasses is that they sleep better at night. Researchers agree that blue light from LED devices such as smartphones and laptops inhibits the body’s production of sleep-inducing melatonin.
According to a 2017 study at the University of Houston, spectacled participants increased melatonin levels at night by about 58%. “By using anti-bluegrass, we can improve sleep while using the device. According to a university press release, Dr. Lisa Ostrin, a professor at the University’s Optometry University, said:
The American Academy of Ophthalmology takes a different approach. “You don’t have to spend more on blue glasses to improve your sleep, you just reduce the screen time at night and set your device to night mode,” explains the group.
“I think I can work longer”
Many consumers say that blue light glasses are useful.
Cindy Tolbert of Atlanta, a retired crime writer and lawyer, has a variety of vision problems and has spent an additional $ 140 on blue light lenses in an ophthalmologist’s office.
“It’s not clear that glasses can help you put on your glasses, but I think you know that you can work longer and more comfortably,” she says. “I usually lose my eyes after 4-5 hours of computer work, but I can work longer with my glasses on.”
Michael Clark of San Diego says he doesn’t care what experts say about blue-light glasses. You are working for him.
“I use them so often that I wear blue glasses around my neck all day,” he said in 2019. “I’m not an optician. All I know is that my eyes don’t do that at the end of the day. I’m tired. I have less frequent headaches. Focus on what’s on the screen. It’s easier to do. ”
In 2019, Erin Satler of Bellevue, Washington, said she would hurt her eyes when she was sold with blue light-shielding glasses. But she changed her mind.
“Further research has shown that bluelight technology is unfounded and primarily a placebo effect,” Sutler said this month. “I’m wearing light glasses right now, and that makes a big difference. I take off my glasses on a regular basis to clean, straighten, and talk to my colleagues in the office, so I think my blue glasses relieved my eye pain. “”
Just order blue glasses with or without a prescription from an optician or online.
Rest your eyes
If you’re worried about how your computer or other blue-emitting screen affects your eyes, you may be relieved without special glasses.

The American Academy of Ophthalmology, the Vision Council, and other vision-related organizations encourage discreet use of screens. We recommend that you adopt the 20-20-20 rule. This means that every 20 minutes you are looking at an object at least 6m away for 20 seconds.
The American Academy of Ophthalmology also recommends the following steps:
• Adjust the position of your seat or computer so that your eyes are approximately 25 inches from the screen. Place it so that the screen faces down a little.
• Use a matte screen filter on the screen to reduce glare.
• If your eyes are dry, use artificial tears.
• Pay attention to the lighting in the room you work in. You can increase the contrast of the screen.
