John, one of the most outstanding ophthalmologists in the UK, and the Institute of Ophthalmology at University College London. Professor Marshall believes that some of the light emitted by energy-saving light bulbs with high intensity, the latest scientific evidence shows that these specific light is particularly harmful to people's eyes and skin. A study in the journal Psychology found that flashing lights may trigger migraine symptoms in some patients and may also trigger seizures.
Would you be surprised if you saw someone who was hoarding old-fashioned incandescent bulbs for fear of energy-saving bulbs that could cause blindness? You might think that he is crazy, but in fact, this problematic person is precisely one of the most outstanding ophthalmologists in the UK, John of the University of London College of Ophthalmology. Professor Marshall. It is because of this worry that his home is already full of old-fashioned incandescent light bulbs.
Before the government refused to import incandescent lamps, I bought the bulbs in large quantities. He said, I can't tell you exactly the exact number, but this amount should be enough for me to always use it for illumination.
He is not the only expert who cares about energy-saving light bulbs, another distinguished British professor, John. John Hawk has the same worries, and the dermatologist warns that modern light bulbs can cause sunburn damage, premature skin aging, and even skin cancer.
There is also no trace of energy-saving light bulbs in his home. He explained that when old light bulbs were still available on the market, I bought a lot of bulk light bulbs. Concerns about energy-saving light bulbs, the "Daily Mail" recent report for us to explain one or two.
Energy-saving lamps may have been hurt for more than a century. Incandescent bulbs are standard lighting tools. However, with the EU's directive, the British government banned the import of 100-watt bulbs in 2009, and subsequently banned the import of 60-watt bulbs in 2011, and in 2012 completely banned the import of all traditional bulbs.
The EU ban is aimed at reducing fuel and carbon emissions. Energy-saving light bulbs, or compact fluorescent lamps, are said to consume less than 80% of electricity and have a longer life. Older incandescent bulbs work by electrically heating the filaments in a glass ball filled with an inert gas. Unlike filament lighting, the energy-saving bulb spiral tube is filled with argon and mercury vapor. When the gas is heated, it produces ultraviolet light that irritates the fluorescent paint applied to the inside of the tube. This coating absorbs energy and therefore emits light.
John. Professor Marshall said that what is worrying is the light emitted by these bulbs at high intensity. The latest scientific evidence indicates that these specific rays are particularly harmful to the eyes and skin.
Different wavelengths of light have different penetrating power. Lights that are harmful to the eyes are mainly high-energy short-wave light, such as ultraviolet light, blue light, and violet light. The most comfortable thing for the human eye is the medium-wave green light. The blue-violet light penetration is stronger than the short-wave ultraviolet light. The energy in the visible spectrum is relatively high. It can penetrate the cornea and the lens and reach the retina. Once the retina is damaged, it will cause irreversible damage. Therefore, the most important damage to the human eye in nature is the short-wave, relatively high-energy ultraviolet and blue-violet light.
Complutense Uni-versityinMadrid, Spain. Kasans. According to research by CeliaSnchez-Ramos, the light emitted by LED lamps is a short-wave high-energy light source, which is blue and violet in the visible light spectrum. It is possible to expose the light to people's retina for a long time. Cause damage.
Kasans. Dr. Raymonds also pointed out that the light radiation emitted by energy-saving lamps can cause serious damage to human retinal pigment epithelial cells. To this end, he suggested that lamps such as desk lamps should not be used as energy-saving bulbs. Try not to look directly at the light source with your eyes, and pay attention to the time of use. Close your eyes every 20-30 minutes and rest for a while.
At the Ophthalmologist Education Forum last month, John. Professor John Marshall warned that continued exposure to short-wavelength light such as ultraviolet light emitted by energy-saving lamps would increase the risk of both eye diseases such as macular degeneration and cataract.
Radiation-damaged skin energy-saving lamps may not only be the risk of eye disease, John John, director of the Department of Rehabilitation, Department of Photobiology, St. John's Skin Institute, King's College London. Professor John Hawk also warned: There is now sufficient evidence that the energy emitted by our forced energy-saving lamps is enough to cause damage to the skin, especially after prolonged use.
He said that if the energy-saving bulbs are less than one meter away from the body, the risk of injury is particularly high, and this is very common because people use them as reading lamps.
There is evidence that energy-saving lamps can not only cause damage to the skin, but also cause symptoms such as sun rashes and lice, which is medically known as pleomorphic sun rash, which occurs after sun exposure to the skin. a delayed allergic reaction. Professor Hawke said that just like the damage of ultraviolet rays, the effect of energy-saving lamps on the skin will accumulate year by year, gradually causing the cumulative effects of skin cell damage, keratinization, etc., although this change is very small, it increases the skin cancer. risk.
Energy-saving light bulbs can also cause problems in patients with lupus erythematosus, an autoimmune disease that usually affects the skin, joints, and internal organs of the patient. The irritation caused by ultraviolet light can cause the disease to worsen, causing rash, joint pain, and fatigue. According to the American Lupus Foundation, up to two-thirds of patients are sensitive to energy-saving lamps. The EU has also acknowledged that exposure to energy-saving lamps may cause skin damage.
Migraine and epilepsy In addition, John. Hawke also stressed that migraine and epilepsy are also problems. I have seen 30 dermatological patients with migraine and epilepsy in the clinic, which are related to these bulbs. This may be because energy-saving lamps are flickering unconsciously, and a study in the 2013 Psychiatry magazine found that flashing lights may trigger migraine symptoms in some patients, as well as triggering seizures.
Spanish and music teacher from Lancaster, 44-year-old Eleanor. Eleanor Levin complained that the energy-saving light bulb made her a headache. She said that she could not stay in a room with an energy-saving lamp like an ordinary person, or it would cause nausea, confusion and migraine attacks. Three years ago, she first discovered the problem in the office where she worked, and she felt a headache. This made me very uncomfortable, and finally I had to give up the job. she says.
Eleanor consulted many doctors and neurologists. Some neurologists told me that they believe the problem is due to migraine caused by flashing light. She said that using old-fashioned incandescent lamps would not bring me this kind of trouble. This is why I am teaching at home to make a living. In addition, the use of halogen bulbs makes me feel normal.
However, Eleanor said that going out at night will still make her worry. Fortunately, there are still many places that use old-fashioned light bulbs to create a mild light environment. The EU recognizes that energy-saving light bulbs can cause skin damage, but headaches are not taken seriously. I suspect that many people suffer the same pains as me and even affect their career development.
In addition, energy-saving lamps may also be one of the causes of seizures, a chronic disease caused by sudden abnormal discharge of brain neuronal cells, resulting in transient brain dysfunction. According to British media reports, about 490,000 people in the UK have epilepsy, and 53 of them have sudden onset due to flashing lights. Many people with epilepsy have dizziness and sudden episodes of epilepsy during the use of energy-saving light bulbs. Other symptoms.
From the current research, it is still unclear how the energy-saving lamps specifically cause the patient's disease. However, there are speculations that this situation may have a certain relationship with the lighting mechanism of energy-saving bulbs.
Hazards of Mercury Leakage The dangers of energy-saving light bulbs may not stop there. It has been reported that energy-saving light bulbs contain a small amount of mercury, which is released into the air or landfill when the glass is broken.
A study by the German Federal Environmental Agency found that a broken energy-saving bulb emitted toxic vapor levels up to 20 times the indoor safety standard. The Public Health Authority of England recommends that if the energy-saving light bulb is broken, the household should evacuate the room and ventilate for 15 minutes. It is recommended to wear gloves when smashing debris and scrubbing the floor with a damp cloth. The debris should be placed in a sealed plastic bag and discarded for special recycling. place.
Another potential problem is that the energy-saving light bulbs that are currently available on the market are mixed in terms of the amount of dangerous spectrum of ultraviolet light that they emit. Harry, director of the Institute of Photobiology at Ninewells Hospital, University of Dundee, UK. Professor Harry Moseley said: Manufacturers have obvious problems with quality control. Our test found that in a batch of ten energy-saving bulbs from different manufacturers, there may be one quality that is obviously worse than others, for example, its shading part is faulty.
He said that single-envelope bulbs are energy-saving bulbs with exposed spirals that emit the highest UV intensity. The double-envelope bulbs have a round glass cover like an old-fashioned bulb that wraps around the spiral to better block some of the UV light.
John. Professor Hawke admits that this measure has improved energy-saving light bulbs, but he said that we are not sure how much it has improved. He has been trying to persuade the EU to ban the import of incandescent bulbs, but no one seems to be interested in it. The EU promotes energy-saving bulbs for environmental protection, but they have not considered the health consequences. They are very reluctant to change this policy.
The Lighting Manufacturers Industry Association insists that the ultraviolet light emitted by energy-saving light bulbs is effectively controlled within the standard and will not cause health damage. At the same time, an EU spokesperson also declared that based on scientific evidence, both the European Science Council and the UK Health Protection Agency concluded in 2008 that the normal use of energy-saving lamps would not pose a risk to general public health.
