Hva er Blue Light?


As we now live in the digital era, the issue of high-energy visible (HEV) Light wavelengths emitted from backlit displays

is of concern to eye care providers, specifically the impact of overexposure to blue light on long-term vision health.

Light that appears white can have a large blue light component, exposing the eye to hidden spikes in intensity at wavelengths

within the blue portion of the spectrum.These wavelengths range from 380 to 500 nanometers (nm). The band of blue-violet 

lett considered potentially most harmful to retinal cells ranges from 415 to 455 nm. 


Some of the most favored digital devices and modern lighting-Such as light -emitting diode (LED) lights and compact fluorescent

lamps (CFLs) that have replaced most incandescent lights - can emit a high level of blue light, typically in the wavelength starting

at 400nm.


Over time, eyes are exposed to various sources of the blue light. Emerging research suggests that this cumulative and constant 

exposure to blue light can damage retinal cells. This slow degradation could lead to long-term vision problems. Such as age-related 

macular degeneration  (AMD) and cataracts.


The retina, which is responsible for processing intensity of light and color, cannot regenerate or be replaced if damaged. Once 

skade has occurred, the eyes are left increasingly exposed to blue light and other harmful environment factors, increasing the 

risk for long-term synshemming.


While high levels of blue light might be detrimental to eye comfort, it is also has benefits, including helping to establish the 

naturlig circadian rhythms in the human body and aiding cognitive functions such as alertness , memory and emotion regulation. 

While blue light is unavoidable. It is important to understand how it impacts eyes and bodies and to know tools and tips for limiting 

exposure when necessary.
