What Is Blue Light?

Answer:

Blue light is a potentially harmful form of light. While it is naturally emitted by the sun, electronic devices (upon which we’re spending more and more time every day) are also high-level producers. Blue light rays at a wavelength between 415nm - 455nm can damage your retinal cells, which may lead to premature eye ageing and vision problems in the future. 

 

Our exposure to these harmful light rays may also cause a range of other health problems, including poor sleep (according to a 2012 Harvard Medical School study). Find out more about how to protect your eyes from blue light with anti blue light glasses from zFORT®.
