Does this sound like your typical day?
You wake up and immediately tap on your cellphone.
You browse the news on your tablet during your commute.
You text your boss that you’ll be late to work.
You diligently stare at your computer screen until 5 o’clock.
You come home from work and catch the evening news.
You end your day in bed binging Netflix on your laptop.
What do all of these things have in common?
YOU ARE BEING EXPOSED TO DANGEROUS LEVELS OF ARTIFICIAL BLUE LIGHT!
What is blue light?
Blue light is the highest energy of all visible light, penetrating deeper into the eye than any other light. In appropriate doses, natural blue light is beneficial. For example, the sun emits a small level of blue light (this is why the sky looks blue!). Blue light, in small doses, boosts alertness, elevates moods, and regulates your sleep cycle. However, in the world we live in today, we are subjecting ourselves to unnatural levels of artificial sources of blue light. In such doses, blue light has been shown to cause premature damage to the retina and other age-related disorders. Our eyes’ natural filters simply cannot protect against prolonged exposure to artificial blue light.
Even scarier is that most of us spend the majority of our day staring directly at a digital screen. In some cases, we stare at a screen for over 6 hours straight! Ever wonder how safe all of this is for the future of your eyesight? Not so safe, apparently.
Why has no one talked about the dangers of blue light before?
The recent growth in digital screen technology has created today’s widely used LED back-lit devices that emit very strong blue light waves. The wide-spread popularity in such devices has dramatically increased our exposure to these dangers. We are truly the first generation of guinea pigs for analyzing how much damage blue light is causing. Only recent studies, including a profound study done by Harvard researchers, revealed that blue light can in fact cause serious long-term damage to our retinas and increase our risk to develop several types of cancers and heart disease.
So, how can we limit our exposure to artificial blue light in a society that demands our daily use of LED back-lit devices? BLUE LIGHT GLASSES!
What exactly are blue light glasses?
We wear sunglasses to protect our eyes from harmful UV rays, so why not protect ourselves against blue light!? Blue light glasses help filter out the blue light emitted by digital screens such as computers, tablets, cellphones, televisions, and fluorescent lighting. Blue light glasses take the strain off your eyes and reduce eye fatigue, ultimately leading to less mid-day work headaches.
Buyer beware: not all blue light glasses are made the same! Stay away from cheap knockoffs. Pixel Eyewear (http://www.pixeleyewear.com) is my favorite brand, because they have very little tint to them. They might seem pricey, but your eyesight is worth it! An added bonus, these glasses are super chic and look like ordinary prescription glasses! For those who wear prescription glasses, ask your optometrist for protective ophthalmic lenses with a special filter to reflect the high energy blue light penetration.
