Filter Light: Recent research suggests that too much exposure to “blue light” can affect our circadian rhythms and cause long-term damage to your eyes. Sun light is our major source of blue light, but we are also being exposed to much more with our display screens of phones, tablets, computers, televisions, etc. The high-energy and shorter wavelength of blue light essentially creates a scattering of “visual noise” that puts a strain on your eyes.
Just like you wear sunglasses to protect your eyes from the sun, glasses with specially-tinted lenses may increase comfort when you’re viewing digital devices for extended periods of time. Some newer smartphones and other devices can even shift their blue light emittance based on the time of day or other factors.
