In reading this blog post, along with anything else on a screen, you’re being exposed to blue light, or high-energy visible (HEV) light.
What is Blue Light?
Blue light is the highest energy light we can see. It falls on the light spectrum just below ultra-violet (UV) light, which is invisible with even higher energy. Sunlight is the main source, but televisions, computers, tablets, and phone screens also generate significant amounts. In addition, fluorescent and LED lights also emit it.
Why Should I Care?
There are a number of impacts. Interestingly, our eyes actually block UV light but not blue light. Too much of this high energy light can damage your retina and lead to macular degeneration. Plus, with more time spent in front of screens of one type or another along with other sources of indoor blue light, we’re being exposed to increasing amounts.
On the other hand, it has been shown to boost cognitive function and memory as well as increase alertness and improve mood. In fact, it is used to treat seasonal affective disorder (SAD). But is can also disrupt your normal sleep patterns as too much blue light at night can potentially cause sleepless nights.
It is also one of the causes of digital eye strain with more than 65% of American’s experiencing digital eye strain symptoms including dry, irritated eyes, blurred vision, headaches, as well as neck and back pain.
What Can I Do About It?
There are two primary ways to reduce your exposure. One is to use a blue light filter that can be attached to the screens of computers, tablets, and smartphones. Another approach is to use glasses that have protection built-in. This is typically a special treatment applied to the lenses.
There are a wide variety of options including glasses to wear just for viewing computer screens, special treated lenses including clear coatings, and lenses designed specifically to reduce blue light, using blue tech technology.
All of them can protect your eyes and reduce eyestrain from long hours in front of a computer.
