There is a lot of commotion in the news regarding the impact that blue light has on the eye. Many people contend that exposure, over time, can damage the eyes and potentially result in blindness. The accuracy of such claims is essential to millions of people who use devices that emit blue light, such as smartphones and smart TVs. So, are the allegations true?
Good news! According to David Ramsey, MD, Ph.D., MPH, the answer to the above question is no! He says that the amount of light emitted is not enough to cause harm or lead to macular degeneration et al. Dr. Ramsey says:
“Compared to the risk from aging, smoking, cardiovascular disease, high blood pressure, and being overweight, exposure to typical levels of blue light from consumer electronics is negligible in terms of increased risk of macular degeneration or blindness.”
