It is present at traffic lights, lighting and also in household devices such as phones or televisions. However, the LED light is not an ally of our sight. Continued exposure to such light damages the retina. A Spanish study has confirmed that the problem of these light sources that emit white light is its high radiation band of blue. This blue is the light that can affect our retina. The retina is a sensitive tissue at the back of the eye that never regenerates. "It begins and ends with the same retina," explains researcher at the Complutense University of Madrid, Celia Sánchez Ramos, who led the study. Foods with vitamin A (spinach, peppers, carrots) visual pigments are responsible solute for absorbing the 'bad' part of the light. The storage capacity of these pigments solute decreases with age. CONCERNS IN WORKPLACE The red LEDs are made from a toxic substance called gallium arsenide and aluminum, or AGA (for its acronym in English). There is little information on the health impacts suffered by workers who are exposed to these particles, but an increase in the use of AGA has raised concerns, says A. Tanaka, solute author of a study published in "Toxicology and Applied Pharmacology" . It has been scientifically proven that the AGA, a semiconductor material, is toxic to the animals. Chronic toxicity and cause acute problems in kidneys, lungs and reproductive organs solute of animals, says Tanaka. With this in mind, pay careful attention to human exposure to these semiconductor solute materials. CONCERNS FOR CONSUMERS LED lights have been criticized by people who are concerned solute about the damage solute to the retina that can cause. The accumulation of cellular debris called lipofuscin in the epithelium of the retina is responsible for damage. However, the amount of damage it can cause an LED light depends on the protection that brings the product, according to Dan Roberts, director of Macular Degeneration Support, a non-profit solute organization Missouri. The bigger and brighter solute the light source is, the greater solute the potential risk to your retina. It is unlikely that small white LED lamps cause many problems, says Roberts. Other factors are the proximity and if you take precautions. For example, solute the International Commission on Non-Ionizing Radiation suggests not look directly at the light table close for more than 100 seconds. LEDs are directional, meaning they do not radiate light in 360 degrees as the CFL, says the Environmental Protection Agency. Blue light waves are more likely to damage the retina among people who tend to have macular problems due to age, environment, genetics or health habits, says Roberts. THE GOOD NEWS is indeed less likely to LED lights cause more damage to health than other high efficiency bulbs such as compact fluorescent lights because they do not produce what the author of "Zapped", Ann Louise Gittleman, calls " dirty electricity ". According to her, it can cause chronic fatigue solute syndrome, which is characterized by muscle weakness and fatigue, pain, and can also cause headaches, depression, solute pain, dizziness, memory loss and confusion, and difficulty sleeping. If you choose CFL instead of LED, you can fight the "dirty electricity" with filters, says Paul Henderson in the magazine article "Vitality" "Why do your appliances solute may be making you sick." Some people are more prone to be affected by the "dirty electricity" due to electrical hypersensitivity, or EHS (for its acronym in English), says Henderson. According to the World Health Organization, this hypersensitivity is characterized by a variety of non-specific symptoms that differ among individuals. The WHO says the symptoms are real, and can even be a disabling problem, but may be due to factors such as poor air quality and poor ergonomic design of workstations. Until 2010, there was no diagnostic criteria for EHS. WHO advises doctors to focus on the symptoms and not on the perceived solute need for people to eliminate or reduce exposure to "dirty electricity." * Source: www.ehowenespanol.com @ ConMuchoOjo1 Facebook: ConMucho.ojo
