Is it harmful for light and people to contact light frequently?

Yes

If the eyes are used indoors for a long time, the ciliary muscles of the eyes are highly tense and the lens is excessively refractive, which will lead to visual fatigue or vision loss. Improper use of light for a long time at night may also cause dizziness, emotional irritability, and even elevated blood pressure and palpitations. Abuse of light at night will inhibit the secretion of melatonin or reduce its concentration, and people's normal physiological rhythm will be disrupted, resulting in insomnia, decreased sleep quality and other problems.

Improper use of light has a particularly serious impact on infants, which not only affects vision development, but also interferes with the central nervous system function of the brain. For outdoor light pollution, there has been a * * * understanding at home and abroad, and the relevant standards limit the brightness of lamps and the emission range of lights.

Extended data

Red color temperature is low, blue color temperature is high, warm color temperature is low (such as morning and evening sunshine), and cold color temperature is high (such as noon sunshine and skylight). It is recommended to use lamps with low color temperature at home, such as those below 3000K (Kelvin). The lamp with low color temperature helps to reduce the inhibitory effect of melatonin, regulate the internal biological clock and make people relax.

Color rendering is the color fidelity of an object under illumination. The light source with high color rendering can better restore the color, and the color we see is closer to the original color under natural light. Using the light source with low color rendering, the color you see will be greatly deviated, and things will deviate from the original color, which will easily lead to visual fatigue. Indoor lamps require a color rendering index above 80. Please pay attention to the label on the light source or lamp when choosing.
