LED headlights have almost covered our life, such as car headlights, LED screen displays, desk lamps, mobile phones, etc. we are slowly integrating into LED life. However, do you think the led around us will do us any harm?
In a 400 page report, the agency warned that led lights could cause irreversible damage to retinal cells and eventually lead to blindness. ANSES urged officials to modify the maximum exposure limit of LED lamps and reduce the number of “blue lights” in LED lamps.
Research shows that led mobile phones, tablet computers and laptop screens will not cause damage to our eyes, but the strong light used in car headlights may damage our eyes. The report distinguishes between acute exposure of high-intensity LED lamps and “chronic exposure” of low-intensity light sources. The agency said that although the risk is low, long-term exposure to this light source can also accelerate the aging of retinal tissue and lead to decreased vision.
LED lamps are durable, energy-saving and low-cost. They have occupied more than half of the lighting market in the past decade. Industry experts predict that the market share of this product will continue to expand and will exceed 60% by the end of next year.
The energy consumption of LED lamp is about one fifth that of incandescent bulb with the same brightness. It has been widely used in home, street, office and industrial lighting. They also appear more and more in car headlights, flashlights and some toys. Ophthalmologist Francine Bihar Cohen said LED phones, tablets and laptop screens would not cause damage to the eyes. He explained that because their brightness is very low compared with other types of lighting equipment. However, these backlight devices, especially when used at night or in a dark environment, may interfere with the biological clock and affect the sleep state.
Dina Attia, a researcher and project manager at ANSES, points out that they will not only interfere with the natural rhythm of the body, but also increase our metabolic disorders and increase the incidence rate of diabetes, cardiovascular diseases and certain cancers. ANSES points out that children are more vulnerable to this interference. In addition, the report said that due to small fluctuations in current, stroboscopic phenomena in some LED lamps may cause headache, visual fatigue and other unexpected risks.
For the families we care about most, warm white LED lighting will be better. Children should also reduce the use of relevant LEDs directly under the light source of high concentration blue LED, and try to reduce the use of relevant LEDs before rest at night. Do these well, so that we can use LEDs healthily.
