Indoor planting is becoming more and more popular, leading to the growing popularity of LED growth lights. LED growth lamps can promote plant growth, shorten plant growth cycles and increase yield. But some people worry that long-term exposure to LED growth lights can cause eye and body health damage.
The LED plant light source is mainly composed of red and blue light sources, using the most sensitive light band of the plant, and the blue light wavelength is 450-460nm and 460-470nm. The full-spectrum LED growth lamp also contains ultraviolet light.
Blue light is a relatively high-energy light with a wavelength between 400nm and 480nm. It is widely present in computer monitors, fluorescent lamps, mobile phones, digital products, displays, LEDs, etc. The blue light in this wavelength causes the macular area in the eye. The increase in the amount of toxins is a serious threat to our fundus health.
What are the specific hazards of Blu-ray:
1. Blue light will aggravate the disease of the macular area of the retina.
With the increase of age, the lipofuscin (cell debris) left by the phagocytosis of retinal pigment epithelial cells will gradually accumulate in the retinal pigment epithelial cell layer, which will cause the retina to illuminate the chronic light. More sensitive.
Blu-ray will aggravate macular problems caused by genetics, nutrition, environment, healthy habits and age-related relationships.
The toxicity of the retina increases with the shortening of the wavelength after prolonged exposure, thereby aggravating the disease in the macula.
2. Blue light can cause fundus damage after cataract surgery
As we age, the lens of the body itself will gradually turn yellow, which helps to filter blue light. However, after cataract surgery, patients lose these natural barriers.
Blue light will reach the retina and damage the retinal pigment epithelial cells, seriously affecting the health of the fundus.
3. Blue light can cause visual blur, leading to visual fatigue, causing VDT syndrome
After the blue light enters the fundus, the focus does not fall on the retina but falls between the retina and the lens.
This increases the distance of the chromatic aberration of the light in the eye, and the distance between the focus of the eye is the main cause of the blurred vision.
Therefore, the injection of blue light will aggravate the chromatic aberration and visual blur. When the eye muscles are excessively tight, the blood supply to the eyes is excessively tight, and the blood supply to the eyes is strengthened, thereby aggravating fatigue.
4. Blue light can cause glare
Blue light has a higher energy between 400nm and 500nm, while higher energy light has a higher probability of scattering when it encounters fine particles in the air, and blue light becomes the main cause of glare.
5. Blue light can inhibit melatonin secretion, disturb sleep, improve the incidence of major diseases
The blue light is enough to stimulate the brain, making the brain excited, affecting the laws of the biological clock, taking too long to fall asleep, and waking up many times during sleep to suffer from insomnia.
UV damage to human
Ultraviolet radiation UV-C is also present under natural light, but almost 100% is absorbed by the Earth’s atmosphere. For artificial light, especially full-spectrum LEDs, UV-A and UV-B radiation are highly likely, but may also be exposed to UV-C radiation, which poses the most serious risk to eye and skin health.
The damage of the LED light to the human body depends on the light intensity and time, so it is normal under normal circumstances. Please do not look directly at the light source with your eyes. If you want to avoid this risk, you can choose to wear protective glasses.
