Before things like computers and cell phones became part of most people’s daily lives, blue light glasses simply weren’t necessary. It’s only in recent years that scientists have noticed the ill effects over-exposure to blue light is having on our bodies. Blue light glasses are their solution to that problem, and they work so well that even allstars like Oprah have hopped on board. But if you’re new to the world of blue light glasses, don’t worry; we’ve got you covered. Here’s everything you need to know.
What is Blue Light?
Before we get into what blue light glasses are, let’s first get into the nitty-gritty science of blue light itself.
Blue light is a range of the visible light spectrum. We're exposed to blue light every day in the form of sunlight, and that exposure is natural. Unfortunately, blue light is also the dominant source of light in most screens, including TVs, tablets, smart phones, computers, and more.
Just as we’ve learned over the years that too much UV exposure can cause damage to our skin, we’ve learned that too much blue light exposure can cause damage to our eyes and our bodies. You might notice this in the form of:
- Tension headaches
- Trouble sleeping
- Dry or tired eyes
And those are just short-term effects. Long-term overexposure to blue light can lead to more serious conditions like macular degeneration and cataracts.
What Are Blue Light Glasses?
Blue light glasses feature technology in the lenses that helps filter out the more harmful high-energy visible (HEV) blue light before it reaches your eyes. Blue light protective lenses can be added to prescription or non-prescription glasses. That’s why you may notice friends, family members, or even YouTubers you follow suddenly wearing glasses when they never did before.
Some people choose to wear blue light glasses all the time, while others only wear blue light glasses when they’re working at their computer or watching television.
What Will Happen If I Start Wearing Blue Light Glasses?
Most people notice a reduction in symptoms like headaches and eye strain. Over time, your circadian rhythm could level out, and you may find that you fall to sleep easier at night, sleep more deeply, and wake easier in the morning.
Glasses are also a fashion-forward statement, so anticipate compliments on your new Peepers. Feel confident about your new look and feel good about protecting your eyes today and into the future!
