Benefits of Blue Light Glasses for Sleep

Benefits of Blue Light Glasses for Sleep

Sleep is an essential foundation for optimal health, yet, people aren’t sleeping as much as they  did before, and their overall quality of sleep has declined.

Ever thought about the side effects of poor sleep? No worries, we did the research for you! 

Side effects of poor sleep include:

  • Cognitive impairment
  • Irritability
  • Impaired immune system
  • Decreased creativity
  • Increased heart rate
  • Reduced accuracy
  • Depression

And the list goes on. More on that here

Artificial light and electronics that emit blue light during the night may contribute to sleep problems. Our digital devices emit blue wavelengths of light, commonly known as blue light. 

Blue light tricks our brains into thinking it’s still daytime and that leads to staying awake and alert longer.

Many studies imply that exposure to blue light in the evening can disrupt our brain’s natural sleep-wake cycle which is essential for the body’s overall health.

Read on for the benefits of blue light glasses for sleep. Trust us, you – and your future rested self – will be thankful you did.   

What is Blue Light

Sunlight is composed of different colors of light – red, orange, yellow, green, blue, and other various shades. These colors have different wavelengths and energy. Light rays with long wavelengths contain less energy, whereas light rays with short wavelengths contain more energy. There is a red end and blue end of the light spectrum.

Blue light is, you guessed it, on the blue end of the spectrum. Blue light has a wavelength in the scope of 380 – 500 nanometers, which makes its energy higher than other visible light rays, whose wavelengths go from 500 – 700 nm.

How Blue Light Exposure Affects Your Sleep

Exposure to the blue light is a double-edged sword. 

Blue light rays emitted from sunlight help us wake up in the morning and improve our brain function throughout the day. They improve our mood and keep us alert. However, excessive productivity from the over-exposure to blue light emission leads to difficulty falling asleep. Ever experienced a rush of productivity late in the evening? How did you feel the next morning? If you’re anything like us at bluwinx, it was probably a rough morning. 

Moreover, exposure to blue light suppresses the natural production of one hormone that helps regulate sleep – melatonin. The lack of melatonin makes it more difficult for us to enjoy a deep, restorative sleep, the type of our body craves after a long day. When it’s time to prepare the mind and body for sleep, the worst thing you can do is expose your eyes to extensive radiation of blue light.

How Can Blue Light Glasses Help You Sleep

A recent study proposed that wearing blue light glasses may work as an effective way to improve sleep, increase work engagement, enhance task performance and organizational citizenship behavior, all while reducing counterproductive work behavior. 

One study suggests that when people use blue light glasses, even in a well-lit room or when using an electronic device, they produced just as much melatonin as in the total dark. 

Another study compared melatonin levels in the evening across dim light, bright light, and bright light with blue light glasses. The bright light almost completely suppressed melatonin production, while the dim light did not. Most notably, those wearing blue light glasses produced the same amount of melatonin as those exposed to dim light. Blue light blocking glasses helped cancel the melatonin-suppressing effect of the bright light.

Blue light blocking glasses have lenses that block or filter out blue light from digital screens. For example, bluwinx blue light glasses are crafted with a unique bwgf Lens technology that filters harmful blue light (up to 80%) and offers 100% protection against UV rays.

In conclusion:

Blue light glasses may help prevent digital eye strain* and minimize the effects of overexposure to blue light – such as sleepless nights and those terrible behind-the-eye headaches. You can experience the benefits of blue light glasses for sleep by trying a pair for yourself.

*Please note, work with your ophthalmologist to determine if you need special eyewear to reduce eyestrain. You may need to use specialized blue light lenses, devices, or eye therapy for activities that cause digital eye strain.
