- You spent a lot of money on the blue light elimination glasses, but they seem to be useless.
- Prolonged exposure to blue light has stolen their previous peaceful sleep pattern.
- But blue light-cutting SLEEP glasses can help. Read on to learn what the SLEEP glasses are.
The corona pandemic has blurred the lines between work and private life. Most people in work-from-home mode complain of having to look at a computer screen 14 hours a day between attending children’s school online and working, while also looking at their phone or laptop screen.
All of this comes at a price. During intense work focused on the digital screen emitting blue light, the eyes sting and the brain begin to pulsate.
Many of us try to reduce our screen time. Some even regulate the screen glare using an app that regulates the day-night mode. Who hasn’t heard of blue light cutter / blocking glasses?
Are Blue Light Cutting Glasses Not Effective?
Ophthalmologist Yuna Rapoport, MD, founder and director of Manhattan Eye, told NBCnew.com. “The short answer is that blue-light goggles don’t help our eye health at all … But screens are harmful to our eyes because when we stare at screens we forget to blink. This dries out our calluses, which can lead to itching, burning and tiredness. “
How blue light steals our sleep:
Ophthalmologist Kara Hartl, MD, has spent over a decade studying the effects of blue light on our eyes and our bodies, the NBCnew.com report says. She said – one of the highest wavelengths that screens make is in the 460 nanometer range, which is where they’re absorbed by melanopsin, a pigment in our eyes that controls our circadian rhythm. Blue light targets melanopsin – when our eyes cannot see blue light, melanopsin signals that it is time for our bodies to sleep. In addition, blue light suppresses the body’s own secretion of melatonin, a hormone that regulates our sleep cycle. Darkness causes our body to start producing and light causes that production to stop.
The connection between circadian rhythms, blue light and sleep:
- Are internally driven cycles that rise and fall during the 24-hour day
- Help you fall asleep at night and wake up in the morning
- The master circadian clock in the brain synchronizes and controls these cycles so that they work together.
- If you use your computer at night and stare at your screen for hours, you’re stifling your sleep cycle on the spot.
According to The Sleep Foundation, light is the single most important factor in aligning the circadian rhythm. When we stare at screens before bed, we are exposed to blue light that makes our brain think it is still daytime and is disrupting our circadian rhythm.
So what’s the point of blue light glasses? They can have a positive effect on our sleep cycle. The truth is that blue-light glasses can mitigate these effects, but not completely eliminate them.
(Do you work on digital screens? Use two blue light blocking glasses – plain blue light cutting glasses during the day and the amber / orange glasses from evening. Or better yet, use the yellow tint option throughout)
Try the yellow tinted blue light cutting glasses:
Some blue light glasses have yellow lenses. Hartl told NBCnew.com that they are “sleeping glasses” because they absorb blue light while allowing other wavelengths – units with which we measure light – to pass through. The darker yellow lenses are, the more efficiently they block blue light. And while clear lenses in blue-light goggles won’t harm you in any way, according to Rapoport, they also won’t help your eye health or your sleep cycle. These clear lenses provide minimal blue light filtering, making them less effective than yellow lenses.
Best sleep mask with blue light blocking:
Hartl and Rapoport recommend blue-light-blocking “sleeping glasses” over conventional blue-light glasses. Hartl suggests wearing the glasses two to three hours before bedtime when looking at screens. You can order the best blue light goggles online or at stores from brands like Felix Gray and Lens Direct, the NBCnew.com report said.
Blue light monsters: protect your eyes, secure your sleep
- Sit 5 to 3 feet from a television. The light emitted by the screen loses energy before it reaches your eyes.
- Computer, telephone or tablet screens are only a few inches away from our eyes and expose us to more intense blue light.
- It is more important to wear blue light blocking glasses when using handheld technology.
- Use blue light blocking screen covers that you can install on your computer, phone, and tablet. Blue light blocking screen covers are a “unique solution”.
- If you depend on blue light cutting glasses, you need to remember to put on your blue light glasses.
- Use night mode on your device when the sun goes down, or download an app like F.Lux.
- Both of these options give your screen a yellow hue and decrease the intensity of the blue light you see.
- Keep your eyes moist throughout the day by using eye drops without preservatives. Keep the drop bottle near your computer and use it all day.
- It can also be helpful to have a humidifier next to your workspace or a desktop humidifier on your desk.
- Follow the 20-20-20 rule: look 20 feet away for 20 seconds every 20 minutes.
The circadian clock is most sensitive to light from about 2 hours before normal bedtime and during the night to about 1 hour after you normally wake up in the morning (this is the sensitive time). Exposure to light during these times affects when your body becomes naturally sleepy and ready to fall asleep.
