Within all visible light, there is a spectrum of colors from red to violet. In that spectrum there is blue light which actually can have benefits; however, overexposure can have negative effects. Blue light comes mostly from the sun but it also emits from phones, electric monitors, and even LED light bulbs. In fact, Blue Light Lenses specifically omit the light from entering our eyes and thus saving us from the harmful effects of overexposure.

The sun provides the most blue light. Because the blue light lowers the production of melatonin, which is what helps in regulating your sleep-wake cycle, it causes you to be more alert during the day. Therefore, over exposing yourself to blue light during late night hours can disorientate our body’s circadian rhythm.

Also, blue light may lead to eye strain from prolonged use of digital screens. In this case, if you find yourself in a profession or hobby that puts you in front of an electric monitor for extended periods, then investing in Blue Light-Blocking Lenses may be a viable option.

Go Out During the Day: Doing this allows you to take in blue light naturally from the sun and reinforces a normal sleep cycle.
