Demystifying Blue Light: What It Is and How to Protect Your Eyes

In today’s digital age, screen time has skyrocketed for all of us. Whether it’s working from home, virtual meetings, online shopping, or streaming our favorite shows, we’re spending more hours than ever in front of screens. The average adult now spends more than seven hours a day on digital devices—a trend that’s only increased with the rise of remote work and online education.

What is Blue Light?

This surge in screen time means our eyes are being exposed to more blue light than ever before. Blue light, emitted by our phones, tablets, computers, and even LED lighting, is a high-energy visible light that penetrates deep into the eyes. While some blue light exposure is normal and even beneficial during daylight hours, prolonged exposure, especially at night, can lead to a range of issues from digital eye strain to disrupted sleep patterns.

Think of it like running a marathon every single day without rest; our eyes, much like our muscles, need time to recover. Constant exposure to blue light without breaks can lead to symptoms like headaches, dry eyes, and blurred vision—issues that have become increasingly common as our screen time continues to climb.

But just as you wouldn’t embark on a physical marathon without proper preparation, there are steps you can take to protect your eyes from the strain of a digital marathon. Using blue light-blocking glasses, adjusting screen brightness, and following the 20-20-20 (below) rule are simple yet effective strategies to give your eyes the break they need.


How to Protect Your Eyes from Blue Light

Protecting your eyes from blue light is a bit like preparing for one of Portland's famous downpours: you wouldn't leave the house without your raincoat, so why neglect your eyes?

  • Use Blue Light-Blocking Glasses: Think of these as your eye's personal rain gear. Available at many optical shops, including Eyes on Broadway, these glasses filter out a significant portion of blue light, reducing the strain on your eyes.

  • Adjust Screen Settings: Just as you’d dim the lights for a cozy evening at home, adjust the brightness on your devices. Most modern screens come with a "night mode" or blue light filter option, which reduces the amount of blue light emitted.

  • Adopt Healthy Screen Habits: Portlanders are known for their love of the outdoors, so take a page out of that book even when indoors. Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for at least 20 seconds. This simple practice is like taking a brisk walk along the Willamette River—it refreshes your eyes and prevents strain.

Conclusion

Just as you wouldn’t head out for a hike in the Gorge without the right gear, don’t let your eyes face the digital world unprotected. Blue light is a reality of our modern lives, but with the right precautions, you can enjoy your screen time without sacrificing your eye health.
