What is the difference between natural light and artificial light?
Natural light refers to sunlight that can be received outdoors.
Artificial light refers to light emitted from indoor light bulbs, lamps, computers, cell phones, and other electronic devices.
Natural light vs. artificial light
The unit for measuring the wavelength of light is the nanometer (nm).
Visible light, the light that is visible to the eye
Light that cannot be seen is called invisible light .
In natural light, each color of light has its own purpose and role.
Sunlight varies depending on the time of day, season of the year, and location on Earth.
All of these changes play a vital role in maintaining circadian rhythm .
Every color of light in natural light has a purpose and a role.
Sunlight constantly fluctuates depending on the time of day, time of year, and location on Earth.
All these changes and the harmony of light waves It plays an important role in maintaining the correct circadian rhythm .
Conversely, in the evening, as sunset approaches, the intensity of blue light and the temperature of all light gradually decrease.
At night, the only source of light available to mankind was fire.
Infrared light, the main wavelength of fire, minimizes the suppression of melatonin secretion and thus does not interfere with sleep.
The effects of artificial light
The popularization of computers, smartphones, and indoor white lighting has changed everything.
Artificial light, unlike natural light, is distorted and unbalanced.
In particular, blue light, the main wavelength of artificial light, has a fatal effect on sleep.
.
The color of light sends signals to the human body.
Blue light - awakening
Green Light - Activity
Yellow Light - Stability
Red Light – Recovery
Sunlight has higher blue light in the morning and afternoon, and as sunrise approaches. Gradually lower the blue light .
At night, artificial blue light signals to the body that it is daytime, a wavelength that is not suitable for nighttime.
Blue light is not balanced with other colors of light,
Exposure to light in the evening, out of sync with the natural rhythm, can have detrimental effects on health and sleep.
Natural light varies to balance the light across the entire wavelength range,
Artificial light emits distorted wavelengths that do not change over time.
During the day, indoor fluorescent lights emit excessive blue light, which is a major cause of chronic eye fatigue and lethargy.
Blue light from cell phones and electronic devices at night can cause sleep disorders and insomnia.
Modern society and artificial light
In modern society, we cannot survive without cell phones and fluorescent lights.
To this end, Luke Eye developed day and night lenses to protect against the unhealthy aspects of modern life while maintaining the convenience of modern life.
Day lenses
Blocks 100% of artificial blue light that causes retinal damage, vision loss, and macular degeneration.
Protect your eyes from artificial screen devices such as smartphones, computers, and TVs.
Night Lens
Blocks 100% of artificial blue light and green light that have a negative impact on sleep.
Promotes melatonin secretion, helping you sleep deeply and recover.
It's time to understand how much light affects our bodies.
A healthy life begins with creating a bright environment.
Experience a new life with Luke Eye!
