Effects of blue light on sleep

How does blue light affect sleep?


First, let's take a brief look at proper sleeping patterns.

Your body recognizes day and night through constant changes in the sun and controls all hormone secretions through your biological clock.

It works to keep you awake and focused during the day, and helps you achieve deep recovery and restful sleep at night.


The phenomenon of falling asleep and waking up through the process of hormonal secretion at the right time is called “circadian rhythm.” What is circadian rhythm?


The correct circadian rhythm is,


During the day - the body secretes cortisol , serotonin , dopamine and other essential hormones to keep us alert and focused.


At night - as the sun sets and it gets dark, melatonin is secreted, which is essential for restful sleep and deep recovery.


Dark nights are essential for the secretion of sleep hormone (melatonin).




The circadian rhythm disrupted by excessive artificial light at night,


It suppresses melatonin secretion, which interferes with the secretion of hormones essential for growth and recovery, and this pattern is repeated, leading to insomnia !


Modern society is a world where we cannot live without artificial light at night.

From LED light bulbs and fluorescent lights to cell phones and computers , these are all sources of blue light, the dominant wavelength of artificial light.



And this blue light sends a signal to your body through your eyes that it needs to be awake, suppressing sleep hormones!ᅠ


Exposure to artificial blue light, especially 1-2 hours before going to sleep, can have long-term detrimental effects on the body.



How does blue light adversely affect sleep?

Blue light is a wavelength of high energy sources.


Higher energy means light travels deeper into the brain through the eyes.

What happens when you receive artificial blue light at night instead of during the day:

  1. High-energy blue light passes through the eyes and reaches the brain.
  2. The brain recognizes that it is morning time and sends a signal to every cell in the body to be awake.
  3. Hormones that must be secreted during the day continue at night.
  4. If you are unable to get deep sleep, recovery, regeneration, and growth cannot occur properly.
  5. As this process is repeated, we encounter various diseases and chronic fatigue through a vicious cycle.


Blue light is necessary during the day when we need to be awake, but

At night, you need to send clear signals to your brain and body that it is time to sleep .



Our eyes cannot detect the difference between natural and artificial blue light.

The brain only receives information from high-energy sources through blue light and sends signals to the human body.


However, blue light before going to sleep artificially brightens the dark night necessary for the secretion of melatonin (sleep hormone) , which is a major factor in adversely affecting sleep.



So what can we do to effectively block blue light at night?

Wake up at sunrise like our ancestors did,


Welcoming darkness at sunset ,


If only fire could be used as a source of light at night,


You will be able to maintain optimal circadian rhythm and sleep patterns.


However, for modern people for whom this practice is practically impossible,

Lucid Eyes has developed glasses that block 100% of blue light so that even modern people can maintain circadian rhythm .

Lucid Eyes Yellow Day Lenses are designed to block 95% of the most harmful range of artificial blue light while allowing harmful colors to pass through for perception, functionality and health.

Lucid Eyes red night lenses It blocks 100% of artificial blue and green light, which are proven to be harmful to health and disrupt sleep patterns and circadian rhythms.
