Things You Should Know Before Investing in Computer Glasses
Blue light can be detrimental to our health and sleep, especially if we get too much exposure during the evening. Limiting our screen time is one way to control and reduce light exposure. But for most people, it doesn’t give enough protection from excessive blue light exposure. This is why you should consider investing in computer glasses. Unlike filters that go over individual screens, these glasses will help limit your exposure to blue light.
However, there are things we need to know before we invest in computer glasses. We need to know why it matters so much to protect yourself against blue light exposure. You also need to know how to choose the best pair of glasses that can get the job done.
What you should know before buying computer glasses
Here are five things you need to know before you invest in computer glasses:
Overexposure to blue light is dangerous
Exposure to blue light isn’t always a bad thing, but it can be disruptive to your circadian rhythms. But because we get overexposed to digital screens and bright nighttime environments, we’re consuming too much blue light, which affects our sleep.
A lot of research says that blue light is indeed harmful to our sleep-wake biorhythms, and these include the following:
- Blue light inhibits the production of melatonin, which is a hormone that is a central regulator of circadian rhythms and is also essential for sleep. Blue light suppresses melatonin more than twice that of other visible light wavelengths. What’s worse is that it alters circadian rhythms by twice the degree.
- While it inhibits melatonin, it also stimulates the production of cortisol, which is a major alerting and stress hormone that can interfere with your sleep.
- Blue light can shorten your sleep time and can lead to more awakenings throughout the night. This results in less refreshing sleep and more fatigued the next morning.
- It inflicts unique damage on the cells in your eyes. Studies show that blue light has a unique way to damage the health and function of your eyes, which raises the risks for eye diseases like cataracts.
- There’s a connection between blue light exposure and elevated risks for certain cancers like prostate and breast cancers. There’s also a connection between diabetes and blue light exposure.
- Adults aren’t the only ones experiencing problems because of blue light exposure. Kids do, too. Children’s exposure to blue light at night can cause their bodies to produce less melatonin and to feel less sleepy at bedtime.
These are the reasons why you need computer glasses. They’re effective in filtering out blue light and restoring your biorhythms and healthy sleep. Here are other things blue light filtering glasses can do:
- Increase sleep amounts and improve sleep quality
- Improve symptoms of insomnia
- Reset your circadian rhythm
- Improve your cognitive performance, which includes learning and memory, and how your brain quickly processes information.
Computer glasses don’t darken your vision
High-quality glasses made with amber lenses are effective in blocking blue light without darkening your vision. Amber lenses can absorb blue light and other stimulating light and it allows others (less alerting light wavelengths) to pass through, to help you see clearly during normal activities. You can work on your computer, read, or watch television without being inconvenienced by your glasses.
Computer glasses can benefit everyone
We all face different challenges with our light consumption. Some of us spend ten hours a day in front of a computer, while others travel constantly and get exposed to light at odd hours of the day. Gamers and streamers log plenty of screen time. A lot of us binge-watch shows on Netflix, which also increases the risk of blue light exposure.
We need to manage light exposure so we can minimize the sleep and health risks of too much blue light, especially at night. When our bodies need darkness in stimulating melatonin production, blue light computer glasses can help all of us. The end goal is to improve your sleep and health.
Apps that claim to block blue light don’t work
Built-in apps are theoretically good, but there isn’t any scientific evidence that shows it can help. They’re not effective at blocking enough high energy light to protect your body’s natural biorhythms. A study in 2018 showed that Apple Night Shift app didn’t reverse the melatonin suppression that arises from evening exposure to these devices. In 2015, a study showed that our pre-bedtime electronics habits affect bio clocks and inhibit melatonin production, decreasing alertness in the morning, and stimulating alertness at night. In 2018, a study showed that using tablets without eye protection led to the suppression of melatonin production, less evening sleepiness, less alertness in the morning, and more.
These features are important when investing in computer glasses
- Clear and amber lenses. Studies show that clear and amber lenses can prevent blue light from reaching the eye. Wearing them can improve sleep quality and correct disruptions to your circadian rhythms. They can also increase your overall sleep amounts and reduce the symptoms of insomnia.
- They should block UV-A and UV-B For them to effectively help you with your sleep, they need to block all the blue light that comes your way. They should also block both UV-A and UV-B light. UV rays are harmful to our eyes and vision. If you are exposed to UV-A and UV-B rays, then you’re more likely to experience cataracts and macular degeneration.
- Anti-glare and anti-reflective. Computer glasses should also be anti-glare and anti-reflective. These features can help ease eye strain coming from spending so much time in front of your computer and other screens. When combined with blue light filtering technology, anti-glare and anti-reflective glasses can reduce the strain and over-stimulation that comes from light-rich environments.
- It’s worth spending money on eyewear that feels good and is easy to wear.
- The warranty should be generous. You’ll need to use these glasses a lot, so there’s a chance that they’ll get stepped on, smashed, dropped, or scratched accidentally. Before you buy them, make sure they come with a warranty that replaces them for a lifetime of use.
