Studies Into Blue Light Blocker Glasses
A number of studies have looked into the effectiveness of blue light blocking glasses. Here are a few examples:
- A 2019 study published in the journal Optometry and Vision Science found that blue light blocking glasses were effective at reducing eye strain in people who worked long hours in front of a computer screen. The study also found that the glasses improved sleep quality in some participants.
- A 2021 study published in the journal Sleep found that blue light blocking glasses helped to improve sleep quality in people with insomnia. The study found that participants who wore blue light blocking glasses fell asleep faster and slept more soundly than those who did not wear the glasses.
Overall, the evidence on whether or not blue light blocker glasses work is mixed. More research is needed to confirm their effectiveness.
It is important to note that the quality of blue light blocking glasses can vary widely. Some glasses may block more blue light than others, and some glasses may not block any blue light at all. It is important to purchase blue light blocking glasses from a reputable retailer and to look for glasses that have been tested and certified to block blue light.
If you are considering using blue light blocking glasses, it is important to talk to your eye doctor first. They can help you to determine if blue light blocking glasses are right for you and recommend a pair that is appropriate for your needs.
Are Blue Light Blocker Glasses Bad For Your Eyes?
There is no scientific evidence to suggest that blue light glasses are bad for your eyes. In fact, some studies have shown that they can be beneficial for people who spend a lot of time in front of digital screens.
Blue light blocking glasses work by filtering out blue light, which is a type of light that is emitted by digital screens. Blue light exposure has been linked to eye strain, digital eye fatigue, and sleep disruption.
Some people may experience side effects from wearing blue light blocking glasses, such as headaches, dizziness, and nausea. However, these side effects are usually mild and go away on their own.
Do Blue Light Blocker Glasses Work?
Yes, blue light-blocking glasses are effective. However, there is a simple yet effective test you may perform to determine whether your blue light protection glasses are effective.
Look at something with a blue light while wearing the glasses, such as the flashing lights on top of police cars or ambulances. If you can’t see the flashing blue light, your glasses have a good blue light filter lens.
Blue light-blocking glasses come in a variety of styles.
However, keep the hue of your new blue-light-blocking lenses in mind. Blue-tinted glasses make everything appear blue, so the blue light is not visible. Computer glasses with clear lenses block roughly 20% of blue light (depending on the manufacturer), which can be adequate to reduce blue light’s detrimental effects. Blue light blockers with yellow, orange, or amber lenses are preferable. Red lenses can block nearly the whole blue light spectrum, but they can also impair color vision.
Does Blue Light Damage Eyes?
There is some evidence to suggest that blue light can damage the eyes. Blue light is a type of high-energy visible light that is emitted by the sun and by digital screens such as computers, smartphones, and tablets.
Blue light exposure has been linked to a number of eye problems, including:
- Eye strain: Blue light can cause the eyes to work harder, which can lead to eye strain.
- Digital eye fatigue: Digital eye fatigue is a condition that is caused by prolonged use of digital devices. Symptoms of digital eye fatigue include eye strain, blurred vision, dry eyes, and headaches.
- Age-related macular degeneration (AMD): AMD is a leading cause of blindness in older adults. Blue light exposure has been shown to accelerate the progression of AMD.
- Cataracts: Cataracts are a clouding of the lens of the eye. Blue light exposure has been shown to increase the risk of cataracts.
It is important to note that more research is needed to confirm the long-term effects of blue light exposure on the eyes. However, based on the existing evidence, it is important to take steps to reduce your exposure to blue light.
Blue Light And Sleep
Blue light exposure has been shown to disrupt sleep by suppressing the production of melatonin, a hormone that helps to regulate the sleep-wake cycle.
Melatonin levels begin to rise in the evening and peak in the middle of the night. This helps to promote sleepiness and lower body temperature. Blue light exposure can suppress melatonin production, making it harder to fall asleep and stay asleep.
Blue light exposure can also disrupt sleep by delaying the onset of sleep and reducing the amount of deep sleep. Deep sleep is the most restorative stage of sleep, and it is essential for physical and mental health.
Reduce Your Exposure To Blue Light
Here are some tips for reducing your exposure to blue light:
- Limit your screen time.
- Take breaks from screens every 20 minutes.
- Adjust the brightness and contrast of your screens.
- Use a blue light filter on your screens.
- Avoid using screens in the hour before bed.
Blue Light Blocking Glasses Benefits
Blue light blocking glasses have a number of potential benefits, including:
- Reduced eye strain: Blue light can cause the eyes to work harder, which can lead to eye strain. Blue light blocking glasses can help to reduce eye strain by filtering out blue light.
- Improved sleep quality: Blue light exposure can disrupt sleep by suppressing the production of melatonin, a hormone that helps to regulate the sleep-wake cycle. Blue light blocking glasses can help to improve sleep quality by reducing exposure to blue light in the evening.
- Reduced risk of age-related macular degeneration (AMD): AMD is a leading cause of blindness in older adults. Blue light exposure has been shown to accelerate the progression of AMD. Blue light blocking glasses can help to reduce the risk of AMD by reducing exposure to blue light.
- Reduced risk of cataracts: Cataracts are a clouding of the lens of the eye. Blue light exposure has been shown to increase the risk of cataracts. Blue light blocking glasses can help to reduce the risk of cataracts by reducing exposure to blue light.
It is important to note that more research is needed to confirm the long-term benefits of blue light blocking glasses. However, the existing evidence suggests that blue light blocking glasses may be beneficial for people who spend a lot of time in front of digital screens or who are concerned about the effects of blue light exposure on their eyes and their overall health.
When To Wear Blue Light Glasses?
You can wear blue light glasses anytime you are exposed to blue light, but it is especially important to wear them when you are using digital screens. Digital screens emit high levels of blue light, which can cause eye strain, digital eye fatigue, and sleep problems.
Here are some specific times when you should consider wearing blue light glasses:
- When working on a computer
- When using a smartphone or tablet
- When watching TV
- When gaming
- When using any other digital device
- When in a brightly lit environment
You may also want to consider wearing blue light glasses in the evening, especially if you have trouble sleeping. Blue light exposure can suppress the production of melatonin, a hormone that helps to regulate the sleep-wake cycle. Wearing blue light glasses in the evening can help to reduce blue light exposure and improve sleep quality.
It is important to note that blue light blocking glasses are not a replacement for sunglasses. Sunglasses are still necessary to protect your eyes from the harmful UV rays of the sun.
