What is blue light and why is it bad for you?
We spend a big portion of our day on a computer, tablet, or smartphone. With these wonderful advances in technology comes a lot of exposure to blue light emitted at close range from these devices. We are also exposed to blue light, in addition to UV rays, from the sun. Blue light electrons penetrate all the way to the retina at the back of the eye. Though the research is just coming out, there is a growing concern about the effects of the exposure of blue light on the eyes.
Blue light can cause oxidative damage to pigment cells, which can, in turn, increase the risk of developing age-related macular degeneration. This especially true for those with light colored eyes and those with a family history of macular degeneration. Of course, age is always a factor, but the research is starting to show that blue light can accelerate the damaging process. 
How can I avoid blue light exposure?
There are various blue light blocking lenses available, such as gunner glasses. Eating green and leefy vegetables can also help, such as spinach, kale, and broccoli. We also recommend trying goji berries.
