Difference between sunlight and artificial light

What is the difference between natural and artificial light?


Natural light refers to sunlight that can be received from outdoors.


Artificial light refers to the light emitted from electronic devices such as light bulbs/lamps, computers, and cell phones in a room.



natural light vs artificial light


A nanometer (nm) is a unit of measure for the wavelength of light.


The light we can see is called visible light.

Light that is not visible to the naked eye is called invisible light.


Every color of light in natural light has a purpose and role.


Sunlight constantly fluctuates depending on the time of day, the time of year and location on Earth.


The harmony of all these changes and light waves plays an important role in keeping the circadian rhythm right.

As you can see in the picture above,


During Noon, all wavelengths of light are at their highest. The reason is that this is the best time for activity and productive work.


In the afternoon (Evening) , as it gets closer to sunset, the temperature of all light gradually decreases with the intensity of blue light (blue light).


At night, until the invention of the light bulb in 1979, the only light source available to mankind was fire.


Red light (infrared), the main wavelength of fire, minimizes the inhibition of melatonin (sleep hormone) secretion and is a wavelength of light that does not interfere with sleep.



However, as computers, smartphones, and indoor white lighting became popular,



everything has changed .



Artificial light is light that is distorted and out of balance when viewed from the natural eye.


And distorted blue light, which is the dominant wavelength of artificial light, has a fatal effect on sleep .


All colors of light play a role in sending signals to the human body .

Blue Light - Awakening

Greenlight - Activities

Yellow Light - Stable

red light - recovery



Blue light is higher in the morning/afternoon, when sunlight is the right time for us to concentrate and be active.


As the sunrise approaches, the blue light gradually starts to lower, and when the sun goes down, the change is almost invisible.


However, seeing blue light artificially at night tells the body that it is daytime, and this wavelength is not suitable for a night when you need to rest.


In other words, blue light at night is no different from a stimulant that signals to the body that it should be awake.


Blue light does not balance other colors of light ,

When exposed to nature in the evening out of rhythm ,


It will have a detrimental effect on your health and sleep .

Sunlight changes according to the balance of light in the entire wavelength range,

Artificial light emits light at distorted wavelengths that do not change with time.


Everything in nature is in balance and harmony .


Living with a distorted wavelength range of light and a narrow gaze

It causes disease and suffering.


Indoor fluorescent lights emit excessive blue light during the day, so

It is a major factor in chronic eye fatigue and lethargy,


The blue light emitted by mobile phones and electronic devices at night is

It is a major cause of sleep disorders and insomnia.

However, in modern society, it is impossible to live without cell phones and fluorescent lights.


Lucid Eyes maintains the convenience of modern life,

Day and night lenses have been developed to wisely protect the unhealthy side !



Day lenses can effectively protect your eyes from artificial screen devices such as smartphones, computers, and TVs by blocking 100% of artificial blue light that causes retinal damage, poor eyesight, and macular degeneration.

Night lenses block 100% of artificial blue light and green light that adversely affect sleep , and stimulate the secretion of sleep hormone (melatonin) for deep sleep and recovery. (how glasses work)

It's time to understand how much light affects our bodies.


A healthy life begins with creating a light environment.
