Through medical experts' research, the most likely harm caused by high-energy blue light is mainly reflected in: aggravating the macular disease of the retina, causing fundus damage after cataract surgery, causing blurred vision, leading to visual fatigue, and causing glare; In addition, blue light can also inhibit the secretion of melatonin, disturb sleep, and increase the incidence of major diseases.

Studies have shown that LED light can accelerate retinal aging and damage the eyes

Back in 2010, France's National Agency for Food Safety, Environment and Labour (ADSES) published a report. In this report, ADSES pointed out that cold light LEDs and blue LEDs are harmful to the eyes and should be banned. These LEDs are mainly used for decoration, and the intensity of blue light emitted far exceeds that of natural lighting and traditional lighting. These high-intensity blue rays cause damage to both the pigmented surface layer and the sensory layer of the retina, accelerating retinal aging and increasing the risk of macular degeneration.

The largest victim group of LEDs is children under the age of 10. Children of this age have neither cloudy lenses nor macular pigment, so they lack resistance to blue light. In order to protect these children, ADSES recommends that the relevant departments review the relevant regulations and strictly monitor the quality of LEDs. In addition, ADSES also advocates labeling LED related products to remind users of the hazards of LED. At the same time, people should try to avoid using white LEDs and avoid looking directly at their light, so as to minimize the harm of LEDs.

Ophthalmologist: High-energy blue light can cause irreversible damage to the eyes

Smartphones and tablets have become part of the household, and the health hazards of these electronic devices are not just entertainment noise, but also the hearing impact. Recently, at the symposium on 'paying attention to children's vision protection from protecting blue light' held in Shanghai, there was such a data that 0.6% of children aged 66-6 in China began to contact electronic products from the age of 4, and played tablets or mobile phones for 1.5-2 hours a day. Ophthalmologists say that high-energy blue light can cause irreversible damage to the eyes.

Experiments have shown that children obviously feel eye fatigue after using electronic products for a long time; Check their visual acuity, all have varying degrees of decline. A child with normal vision, after half an hour of continuous use of the tablet, his visual acuity level rises by a row on the eye chart, which indicates that the vision is moving in the direction of myopia. The culprit for children's vision loss is actually the 'blue light' emitted from the LED display such as computers and phones. Scientists have found that the degree of harm to the eyes of blue light varies by age, from 6%-19% for 80-90 years old, 20%-39% for 60-70 years old, and 40% for 60-50 years old. Li Junping, a clinical ophthalmologist at the University of Virginia, said that the damaging effect of high-energy blue light is a chain reaction, first causing the death of light-sensitive cells, causing macular degeneration of the retina, and then leading to gradual decline or even complete loss of vision, and this damage is irreversible.

The optic cells and visual cells in the human body are more sensitive to blue light, and high-intensity blue light will cause damage to the optic cells. In older people, crystals will turn yellow with age. In fact, yellow can be and part of blue light. Children, sensitive to strong blue light, can cause damage to visual cells, affect vision, cause vision loss, and even develop glasses diseases.

Through research, medical experts have found that the most harmful causes of high-energy blue light are mainly reflected in: aggravating retinal macular diseases, leading to fundus damage after cataract surgery, causing blurred vision, leading to visual fatigue, and causing glare; In addition, blue light will also inhibit the secretion of melatonin, disturb sleep, and increase the incidence of major diseases.

Statistics show that from the first mobile phone in 1973 to the present, more than 50% of people around the world pick up their mobile phone first thing after waking up in the morning. The latest medical research shows that the background light source of tablet monitors and mobile phone screens contains abnormal high-energy blue light, which can directly penetrate the lens to reach the retina and damage the retina, especially increasing the chance of macular degeneration, and severe cases will cause blindness! The World Health Organization (WHO) Eye Care Association has issued an orange warning: the potential hidden threat of blue light radiation to human beings will far exceed the destructive nature of Sudan red, melamine, SARS (SARS), and H1N1 viruses, which will invisibly devour people's eyes.
