At present, there are different evaluations on the function of products against blue light, but it is generally believed that blue light is harmful to eyes. Blue light is high-energy short-wave light with a wavelength between 400 and 500 nanometers, and it is the most penetrating visible light. The biggest source of blue light is sunlight, followed by fluorescent lamps and LED lamps.
Retina is highly sensitive to blue light, so blue light can easily lead to visual fatigue, accelerate macular degeneration, induce irreversible damage to retina, and then lead to decreased visual function.
Therefore, the LED light on the cosmetic mirror is very close to the user, and the user's vision is more concentrated when making up and removing makeup, which is more likely to cause visual fatigue under the influence of blue light. Long-term use will definitely increase the risk of related eye diseases.
In addition, blue light has also been proved to affect the circadian rhythm of the body. In other words, if you use it when removing makeup at night, long-term application will also affect the sleep rhythm, which may lead to sleep disorders.

Mainly used as vanity mirrors, furniture accessories, solar cookers, car lamps and searchlight reflectors, reflecting telescope, car rearview mirrors, etc.
The above is the introduction of the difference between cosmetic mirror and ordinary mirror. Cosmetic mirrors have higher requirements than ordinary mirrors, and different proportions of magnifying surfaces of cosmetic mirrors can provide better visual sense for makeup.
