Can blue light blocking glasses help with sleep quality and recovery from exercise? Here is our block blue light review.
What is Blue Light?
Blue light is a type of light with a specific wavelength of 400-495 nanometers (nm). Blue light is not necessarily bad for us and is a part of the visible light spectrum. Blue light is found naturally in nature, such as in sunlight, and is also found in artificial light such as modern LED lighting, and is also emitted from modern technology such as TV and computer screens, as well as smartphones.
Blue light in sunlight differs somewhat from artificial blue light as it is balanced with other wavelengths, depending on the time of day. In the morning there is less blue light and more red light, and in the middle of the day, there is more blue light and less red light. Towards the end of the day and into the evening blue light once again decreases and red light increases.
Blue light plays an important role in regulating our circadian rhythm, and has a positive effect on energy, alertness, and mood, as it rises in the morning and peaks in the middle of the day. As it starts to decline in the afternoon and into the evening, it signals our bodies to shift into a more relaxed state, and in the evening the brain will start to produce more melatonin to prepare for sleep.
Artificial Blue Light In The Modern World
The overexposure to artificial blue light, especially at night, can affect our body’s circadian rhythm and can suppress melatonin production which can affect sleep quality. Exposure to blue light in the evening from TVs, computer screens, and smartphones, will send a signal to the brain that the sun is still up. Artificial blue light can also penetrate the retina of the eye and can cause damage over time, such as macular degeneration.
What Are Blue Light Blocking Glasses
Blue light blocking glasses are glasses designed to block out blue light emitted from computer and TV screens, smartphones, modern LED lighting, and other artificial light sources. Depending on the type of blue light glasses, specific wavelengths of blue light are blocked. By using blue light blocking glasses, especially at night, we can negate some of the detrimental effects of overexposure to blue light, and can potentially improve our sleep quality.
Sleep quality as well as duration is important for our overall health, and will also have a major impact on our recovery from hard exercise or training and can therefore improve the results we are likely to achieve whatever our fitness goals are. Poor sleep quality will result in less energy and focus to train hard, will affect our overall mental health and well-being, and will make things such as fat loss and building muscle more difficult.

Blockbluelight sells different types of blue light blocking glasses, designed for various uses and will block out varying amounts of blue light, depending on the type of glasses. Their computer glasses are suitable for daytime work, while their nighttime glasses provide maximum protection from artificial blue light.
Daytime Clear Lenses
Daytime blue light blocking glasses with clear lenses block out around 50% of blue light and will have minimal color distortion. These daytime blue light blocking glasses will target blue light in the 455nm wavelength, which is the strongest wavelength of blue light emitted by computer screens, smartphones and tablets, and LED lighting. These types of blue light blocking glass are designed for daytime use, allowing for beneficial wavelengths of blue light which is important for daytime energy and alertness.
Daytime Yellow Lenses
The next level of protection from blue light is daytime blue light blocking glasses with yellow lenses. These glasses will block 100% of blue light in the 400-455nm wavelength, which is the most damaging wavelength emitted by screens and LED lighting. These lenses will still allow for the beneficial blue light in the 455-500nm wavelength, responsible for hormonal production, energy, alertness, and mood.
Nighttime Amber Lenses
The top level of protection from blue light is the nighttime blue light blocking glasses with amber lenses. These blue light blocking glasses will block 100% of the entire blue light spectrum in the 400-500nm wavelength. These glasses are designed to be worn at night and will block out all blue light which can disrupt our natural circadian rhythm, suppress melatonin production, and affect our sleep quality.
My Experience With Blue Light Blocking Glasses
For the past year, I have been using blue light blocking glasses in the evening, and more recently I have purchased daytime blue light blocking glasses, as I am now getting more screen time working on my computer during the day.
NightFall Wrap Blue Blocking Glasses
I have been using these NightFall Wrap Blue Blocking Glasses for the past year to improve my sleep quality. These are their maximum protection night glasses blocking 100% of blue light as well as green light. They also have a wrap-around fit to minimize leakage of unfiltered light.
They have a somewhat cheap and plastic feel to them, compared to my new DayMax ELITE Glasses, however, they are comfortable to wear, especially with the padding on the inside which ensures a good fit, and does not allow any light to enter from the sides.
I have found the NightFall Wrap Blue Blocking Glasses to be effective at improving sleep quality, and I believe they have been a good investment. I rarely have trouble falling asleep, and pretty quickly, even if I have been working late on the computer, watching TV, or spending too much time on my smartphone. I often have trouble staying awake in the evening, especially on those long dark winter evenings. How much of this is due to these glasses is hard to tell, however, I do believe they are positively affecting my sleep quality, and I will continue to use them.
DayMax ELITE Glasses
More recently I have purchased some daytime blue light blocking glasses, to help with eye strain and the potential damage blue light can cause to eye health, especially now I am spending more time looking at a computer screen during the day. I was happy with my nighttime glasses, so I purchased the DayMax ELITE Glasses.
These glasses have a more premium feel compared to my nighttime glasses, and they feel like they are good quality overall. These glasses block out 100% of the most damaging wavelengths of blue light, while still allowing some blue light through to help with alertness and energy throughout the day. Importantly you are still able to see different color shades when working. I always use these during the day and often use them in the early evening when I’m watching TV and still want to be able to see different colors, for example when I’m watching a football game. Using the nighttime glasses in this situation would result in everything looking red!
I feel these glasses are effective and I do feel less eye strain after working on the computer for multiple hours in the day. More importantly, they are protecting my eyes from the most damaging spectrum of blue light so I see them as a worthwhile investment.
Red Light Reading Lamp
I have also purchased a red light reading lamp. The Twilight Red Light Sleep Lamp is a portable, rechargeable bedside lamp that provides an optimal evening light source that is 100% blue and green light-free. It is also flicker-free and low EMF, which is exactly what you want for nighttime lighting. The lamp is gooseneck, has 360-degree flexibility and can be easily adjusted to your desired position. It has 3 brightness settings, and a touch sensor control, and is also highly portable, making it great for travel.
This is a great little lamp that I use all the time. You can easily move it around the house, or buy multiple lamps. I keep it at my bedside during the night, so I can use it if I need to get up in the night. This way I do not have to turn on bright blue light which could disrupt sleep quality. The battery lasts a surprising amount of time, you can also plug it in permanently via a standard USB charger so that it does not need recharging.
Conclusion
In my experience, BlockBlueLight seems to be a great company, and I have found their products to be good quality and effective at improving sleep quality. They have great customer reviews, and clients and friends I have recommended them to are happy with the items they purchased. If you are looking to improve your sleep quality and negate some of the detrimental effects of overexposure to blue light I recommend BlockBlueLight highly.
