What is Blue Light?
Blue light is visible light in the 380-500nm wavelength range.
Modern white LEDs, commonly used today, achieve white light by combining blue light sources with yellow phosphors, resulting in a higher proportion of blue light even at the same light intensity.

Concerns about Excessive Blue Light Exposure
Prolonged exposure to blue light can suppress melatonin production.
Melatonin is a substance secreted in the brain that induces sleep.
Therefore, suppressing melatonin can disrupt sleep and circadian rhythms, potentially affecting overall health.
Additionally, the high energy of blue light is believed to have a significant impact on the eyes.
