 Blue light has become increasingly prevalent in our modern world due to the rise of lead technology and digital devices. While it may not be immediately harmful, prolonged exposure could lead to serious ocular damage over time. There is currently no evidence that LEDs in normal use or screen devices are detrimental to the human eye, but more research needs to be done to understand the full extent of their impact. Additionally, there is no evidence that blue blocking lenses offer any protective benefits against eye disease. Instead, antioxidant vitamins like Vitamin C, E and Zinc, as well as macular pigment found in foods and supplements, may help reduce the risk of ocular damage caused by blue light exposure.
