Is LED plant growth lamp really useful?
Mainly the eyes: very strong light can cause short-term cornea, especially macular retinal injury, manifested as pain photophobia, visual acuity plummeted to blindness. The light source in the chronic injury month after month and year after year strong light, can cause lens opacity, retinal edema, macular degeneration and necrosis of photoreceptor cells and decreased vision and even blindness. Acute light injury can recover if the damage is not deep and timely treatment. The chronic light damage is easy to ignore due to the slow development, but it is easy to cause irreversible damage.
The main danger to us is the blue light, which we often hear about the so-called LED blue light
Of course, there are hazards, because the light source of this light is mainly composed of red and blue light sources, using the most sensitive light band of the plant, red light wavelength using 620-630nm and 640-660nm, blue wavelength using 450-460nm and 460-470nm
