Blue light blocker glasses are all the rage, and an increasing number of people are buying them in order to preserve their eyesight; but, is saving eyesight the only thing these glasses can help with? Blue light messes with your brain, and forces your eyes to believe it is the "awake time", even after dark. Our internal clocks run off of the light wavelengths sent, and looking at various screens, or even having a light on, can mess this clock up. By using blue light blocking lenses, you can actually improve your sleeping pattern and quality. On top of this, using these glasses can improve your mood, and has been known to help those with Bipolar Disorder. This is due to the large role that light plays in our hormones and electric signals in our bodies.
Most blue light blocking glasses are yellow in tint, but there has been some new designs where virtually clear lenses provide the same coverage with minimal color distortion. All in all, these things are pretty cool!
