What is Blue Light?

Blue light has very short, high-energy waves. In fact, they’re only slightly longer and less powerful than ultraviolet (UV) waves (which are too short for people to see with the naked eye). Health experts have warned against the harmful effects of UV rays, which can damage your skin and your eyes. High-energy blue light waves are nearly as powerful.

What Produces Blue Light?

Human beings are exposed to more blue light than ever because of the widespread use of devices that rely on light-emitting diode (LED) technology.

Computer and laptop screens, flat-screen televisions, cell phones, and tablets all use LED technologies with high amounts of blue light.

What Does it Do to Your Eyes?

Your eye is equipped with structures that protect it from some kinds of light. Your cornea and lens protect the light-sensitive retina at the back of your eye from damaging UV rays, for example. Those structures don’t keep out blue light.
And you’re exposed to a lot of it — the natural blue light from the sun far exceeds the amount from any one device.

Blue Light and Digital Eye Strain

Using digital devices up close or for long periods can lead to digital eye strain. Research has shown that when people use computers, laptops, and other digital devices, they tend to blink less often than normal. Fewer blinks can mean less moisture and more strain on your eyes.

Digital eye strain means different things to different people. When your eyes are strained from staring at a blue-light-emitting screen, you might notice:

•Dry eyes
•Sore or irritated eyes
•Tired eyes
•Headaches
•Facial muscles fatigued by squinting

Anti Blue light glasses help increase contrast on your screen, making it easier to focus and subsequently reduce eye strain.
