Blue Light

Visible light is much more complex than you imagine. The natural sunlight outdoors, overhead lights indoors, and even light emitted from our digital devices are all forms of light that can affect your eyes. Though many of us are aware of sunlight and the hazards UV light can pose, what about the other sources of light such as blue light?

What is Blue Light?

Blue light is quite high in intensity along the visible light spectrum and is just below UV radiation levels. Blue light has a wavelength of between approximately 380nm and 500nm making it one of the shortest, high-energy wavelengths. The short, high-energy waves of ultraviolet and blue light can cause various changes to the body. Though in moderation some exposure can be beneficial, too much exposure can cause sunburn or increase your risk for developing certain health conditions such as skin cancer, cataracts, or macular degeneration.
