About 60 percent of us spend an average of six hours of our day staring at a screen. When you think of the amount of time we spend looking at our phones, computer screens and TVs, perhaps that number is not surprising. People have known for years about the harmful effects of too much screen time, such as obesity and behavioral health issues.
With an ever-increasing amount of time being spent staring at screens, we’re also seeing an increase in vision loss. Screens give off blue light, which is part of the visible light spectrum. Natural blue light from the sun is actually the type of light that helps us know when to wake up and helps us stay awake. However, blue light is also emitted by our phones, computers and TV screens.
Over exposure to this “artificial” blue light can have serious and long-term effects on our vision and overall health. Too much blue light exposure can lead to blurred vision, eyestrain, headaches, sleeplessness and, in extreme cases, permanent eye damage and vision loss. While reducing your screen time can help protect your eyes, digital devices have become a facet of our lives and, as far as we can see, they’re here to stay. Thankfully, there are other, simpler ways you can prevent the harmful effects of blue light.
Essilor, a leader in quality vision care solutions worldwide, created the Crizal Prevencia lenses, one of the top-brands we carry at our optical boutique in Oshkosh, WI. These lenses are not only clear, easy to clean and eliminate glare, they also help protect against blue light. Essilor uses advanced technology to embed their lenses with a blue light filter. In fact, Crizal Prevencia lenses reduce blue light exposure by at least 30 percent.
Crizal Prevencia lenses are different than other blue light-minimizing lenses. Here are just a few ways that these lenses outperform the competitors:
- They block specific wavelengths of blue light: Unlike other similar lenses, Crizal Prevencia does not block out all wavelengths of blue light—it only blocks the narrow band of harmful blue light. These lenses won’t block out the spectrum of blue light that is responsible for regulating your sleep/wake cycle.
- Blocks other types of blue light: Crizal Prevencia not only blocks harmful blue light from tech devices—it also blocks harmful blue light from the sun and LED and fluorescent lights.
- No yellow tint: Many blue light-reducing lenses are tinted yellow, because yellow helps filter out the blue light. However, this yellow tint also affects other colors, making everything you look at appear to have a yellow tint. Crizal Prevencia, on the other hand, is a clear lens.
If you want to protect your eyes from harmful blue light, choose Crizal Prevencia. These lenses are the very best in performance and blue light protection. At Dr. Jill’s Optical Shoppe, we carry a wide selection of eyeglass and contact lenses at our optical boutique in Oshkosh, WI, including Essilor brands.
