Screen Glasses. For A Better Night’s Rest!

Sleep glasses

Here’s how blocking blue light helps you get some good quality shut-eye.

Have you heard that scrolling through your social media feeds just before going to sleep can hurt your sleep quality?

That’s right, we are all guilty of that habit and yet,  it decreases the standard of our resting state : it becomes harder to fall asleep and we don’t feel especially refreshed in the morning. 

We’ve been there and there’s a  promising solution to the problem , keep reading to learn what you can do to ensure a better night’s sleep every day!

 

What are sleep glasses?

Also known as blue light glasses,  sleeping glasses  are  designed to efficiently block blue light by offering an extra layer of protection against blue light’s strongest wavelengths to avoid the disruption of your circadian rhythms  (sleep patterns) .

OZRAY’s sleep glasses are made with high quality organic CR-39  lenses which efficiently block 100% of the blue light under 410nm and 45% of the blue light on the 410nm – 450nm spectrum.  They are also  very stylish, comfortable, and easily adaptable! 

Sleep glasses are one of our best allies for maintaining a stable circadian rhythm. Is that too much scientific jargon? Let’s go step by step:

 

The effects of blue light overexposure on circadian rhythms

Blue light is a natural source of energy from the sun.  It energizes us and boosts our activity. The problem comes when we  spend so many hours in front of digital devices, which also emit blue light: the artificial kind. 

Overexposure to that last type of light, also called  HEV,  can have negative effects on our overall health. 

The most known symptoms are the so-called  Computer Vision Syndrome and Digital Eye Strain  which include headaches, dry eyes, blurred vision, eye discomfort, and even neck and shoulder pain. 

But there’s a  lesser-known side effect of too much blue light  that is, however, really important to prevent if we want to start the day off on the right foot:  the disruption of sleep cycles.

 

What is a circadian rhythm?

Think of the  circadian rhythm as your inner body clock . The one that tells you when to go to sleep and when to wake up. 

We have all probably experienced those surprising mornings when we wake up exactly a minute before our alarm clock, or even naturally waking up when we have forgotten to set our alarm the night before! Yes, we know that strange feeling of self-satisfaction!

That’s all because of our circadian rhythm:  a natural and internal process that regulates our sleep patterns every 24 hours on average. 

Did you know that plants, animals, and even fungi also have a circadian rhythm?

 

Blue light and sleep patterns

Overexposure to blue light plays a big part in our problems with falling asleep at night: it turns out that too much of that  light blocks the hormone melatonin, a very important element that helps us feel sleepy. 

It is agreed that blue light is an important source of energy for us, it helps us  boost our alertness and our cognitive performance during the day.  But when the sun goes down and night begins, that is when prolonged exposure to this kind of light can have  negative effects on our sleep quality. 

According to a  study by researchers in Toronto , the levels of melatonin in people exposed to bright indoor light wearing blue light glasses compared to the levels of people exposed to dim light without blue light blocking glasses were very similar. Such findings suggest that  blue light is a strong suppressor of melatonin.

 

Did you know?  A new kind of photoreceptor in the human eye was first discovered in 1998, which was then later revealed to be incredibly sensitive to the effects of blue light!

More than 20 years later, light consumption is still a major debate! Some tech businesses are even starting to add different spectrums of light into their digital devices to better adjust their screens to daylight and night. If you have an Apple, you may have turned the  night shift  on. 

This option automatically changes the colors on your screen to the warmer end of the spectrum to reduce the impact of blue light overexposure. 

Let’s sum up:  overexposure to blue light especially at night time  decreases our levels of melatonin by boosting our feelings of alertness.  That has a  direct impact on the difficulty we experience in falling asleep and the quality of our sleep cycles. 

 

Indoor artificial blue light sources 

It is a common misconception for us to believe that our houses are free of artificial blue light! 

The truth is that it’s probably not the case. Many indoor artificial blue light sources have become such basic factors in our daily lives that we don’t even realize  how much artificial blue light we are constantly absorbing. 

These are the most common artificial blue light sources we can typically find in our homes. 

 

  • TVs
  • Smartphone screens
  • Computer monitors
  • Tablets 
  • Gaming consoles and systems
  • LED bulbs
  • Fluorescent light bulbs

 

There are more artificial blue light sources in our houses than we might think. That is why a very important first step is to  become aware of our   blue light consumption.  

From there, we encourage everyone to  reduce, as much as possible, exposure to HEV light an hour before going to bed. 

Make sure that your bedroom is blue light savvy!
