A study claims that LED lights cause retina damage.
A new study shows that LED lights, or light emitting diodes might cause permanent retina damage.
Researchers from Complutense University in Spain conducted a study on the effects of LED radiation and found that it damaged “human retinal pigment epithelial cells in vitro”.
LED lights have a blue band of light that is likely the cause of the damage.
Prolonged exposure to LED lights may be hazardous since many electronic devices, along with street and traffic lights have been replaced by LED lights.
Doctor Celia Sanchez Ramos, co-author of the study, said: “This problem is going to get worse, because humans are living longer and children are using electronic devices from a young age, particularly for schoolwork.”
People reportedly have their eyes open for 6 thousand hours a year, and much of the time is spent in artificial lighting.
Another energy efficient light source has also been criticized for containing the heavy metal mercury, and for giving off too much ultraviolet radiation.
Compact fluorescent light bulbs, known as CFLs save energy, but at high exposure levels they might cause skin cancer, or skin cell damage.
