As we continue to work and learn from home, the amount of time we spend in front of a screen is probably more time than we spend doing anything else. Today’s world runs on digital. From the living room to the board room, we rely on our devices to stay informed, connect with others, attend classes and in many cases, earn a living. Mobile devices and computers deliver countless benefits.
However, they can also have an unpleasant side effect – more exposure to blue light.
What is blue light? And how does it impact our eyes?
Blue light is the range of light with the highest amount of energy in the visible light spectrum (the light we can see). Modern devices like smartphones, tablets, and computer monitors all emit blue light. While historically we’ve gotten our daily dose of blue light from the sun, our increased exposure to blue light from these modern devices has been linked to the onset of digital eye strain.
Why does blue light exposure matter?
Your eyes weren’t built to process blue light well; so, they work extra hard trying to bring this light into focus. Think of it like running a marathon where someone keeps moving the finish line back. With 63% of U.S. employees now working from home and parents reporting a recent 500% increase in children’s online screen time, exposure to blue light from digital devices is at an all-time high. Your eyes are putting in overtime daily which can contribute to digital eye strain and symptoms like tired eyes, blurred vision, headaches, and dry eyes.
Is there something that can help?
There are two types of products that can help reduce blue light exposure:
- A premium anti-reflective coating that targets blue light wavelengths associated with digital eye strain. Because this coating both absorbs and reflects blue light, it has an attractive, near-clear appearance that provides better cosmetic appeal than other blue-light lens products.
- Light-reactive lenses offer comparable blue light filtration indoors in their clear state. Outdoors, the lenses darken and increase the amount of blue light filtration from sunlight to match the increased intensity of the source.
