Facts and Myths about Blue Light Debunked

Digital Eye Strain is a medical condition that is popping up in news stories everywhere. You’ve probably read about how electronic devices emit harmful blue light, which affects eye health, vision and sleep cycles.

But, there’s so much information available, how do you sort fact from fiction? BluTech Lenses will help shed some light on the subject.

MYTH: Blue Light Is Not Natural

While blue light didn’t make breaking news until electronic devices, such as computers, laptops, tablets and Smartphones became more commonplace in society, blue light exists in nature. Natural blue light is emitted from the sun. Typically, the human body is programmed to absorb a set number of daylight hours; however, when we alter that to be on electronic devices at night, we disrupt our circadian rhythms.

FACT: Our Eyes Can’t Block Blue Light

UV light isn’t able to penetrate the inner structure of our eyes, but blue light can. Studies show that nearly 100% of the blue light we are exposed to reaches our retinas.

MYTH: All Blue Light is Bad for You

Blue light linked to electronic devices has gotten a bad reputation for being unhealthy and causing damage to our eyes. However, certain types of blue light are positive and healthy for our bodies.

Scientists have determined that people that suffer from Seasonal Affective Disorder, a type of seasonal depression, experience improved sleep patterns when they are exposed to large doses of blue light during the daytime or artificially at one time.

FACT: Blue Light Can Cause Digital Eye Strain

Staring at a computer for an extended period can lead to eye strain. Symptoms include red, dry or sore eyes, headaches or blurred vision.

MYTH: Digital Eye Strain is Unpreventable

It’s important that we give our eyes a break from digital screens. Regularly practice the 20-20-20 rule, which says that every 20 minutes you should stare about 20 feet ahead of you for about 20 seconds.

Blue light blocking glasses, such as BluTech Lenses, are helpful in blocking harmful blue rays while you are working on digital devices.

FACT: Blue Light Can Accelerate Macular Degeneration

While researchers are working on the links between overexposure to blue light and Macular Degeneration, experts believe these two are connected. Future studies will reveal more information.
