The more time we spend at home staring at screens, the more vulnerable we are to centre strain. Yous've probably already heard of blue lite and how information technology tin can hurt your eyes. Maybe a pair of bluish light blocking glasses even caught your attention. But it's important to understand that yous have lots of options for reducing eye strain when staring at screens beyond just getting new lenses. Here's what you should know about blue low-cal and some of your choices for reducing your exposure to it.
What Is Blueish Low-cal?
On the most basic level, blue calorie-free is exactly what it sounds like: light that's blue. That's not the total moving-picture show, though, and this is where lite and colour theory comes into play, forth with concepts like color temperature, Planck'due south Constant, and the black body radiation curve. Without going too far into the weeds, you lot simply need to empathize one fact about light: The color white isn't universal.
In that location is no singular white, but a whole range of visible light that counts equally white. Depending on the lighting weather and what is radiating and reflecting low-cal, white light tin appear very yellow (warm) or blueish (cool) in color. For instance, the light coming from an incandescent LED light bulb is warmer than the lite coming from a computer monitor. This effect is called colour temperature and is measured in kelvin (1000).
What nosotros perceive as white light shifts along a range of well-nigh two,700K to seven,000K. Confusingly, warmer light has a lower color temperature than cooler calorie-free, with the almost fiery glow of tungsten hitting around ii,800K and overcast sunlight striking most six,000K. Computer monitors typically set up white at a very absurd temperature to emulate natural sunlight, shut to 6,500K. That means the low-cal coming from your screen is quite bluish; you can observe this divergence if yous compare a web page with a white background to a warm light bulb.
Blueish calorie-free is oft cited as the culprit for eye strain and even middle damage, and so, naturally, the solution should be to warm that light up before it hits your optics.

Hither's where information technology gets tricky: claims from manufacturers of blue light blocking glasses that don't necessarily concur up to medical scrutiny.

The American Academy of Opthalmology notes that ultraviolet radiation can damage eyes but that computer monitors and other screens don't emit that kind of radiation. The whites are cool, but they aren't harmful. In fact, the AAO doesn't recommend any special eyewear for computer utilize.
This doesn't mean yous should but ignore the furnishings of staring at a screen all day.

It's a problem we've seen pretty consistently with this concept.
