Don't stare into the sun—that's a given. But what about digital devices? You likely spend more hours on your phone or tablet each day than you should, but is this really doing any harm? Let's dive into this a bit further...
High-energy visible (HEV) light—often referred to as 'blue light,' near the ultraviolet (UV) end of the visible spectrum—is not only found in sunlight, but also in the light sources people use every day. Blue light emitters such as smartphones and other digital devices, compact fluorescent bulbs, and LEDs aren't just common, they are fixations of our attention for hours on end.
According to a 2014 American Eye-Q® survey, 55 percent of respondents report using an electronic device for five hours or more daily, and that number is likely much higher today. Add in the hours of TV people watch, and blue light exposure is at an all-time high.
So what makes this information so alarming? Recent research indicates that all of this blue light exposure may be causing ocular harm, possibly contributing to the development of age-related macular degeneration! Research is beginning to suggest that long-term exposure to blue-violet light below 460nm may contribute to damage of the retina, the light sensitive tissue in the back of the eye. Over time, this increases that macular degeneration risk.
This information is super worrisome in my book, especially for children growing up today who have never known life without smartphones and iPads. Obviously, there is no way of knowing yet how these children will ultimately be affected by blue light, but why should we wait to find out?
ZEISS DuraVision® BlueProtect is a fantastic lens that reflects parts of the blue-violet light emitted by these sources, preventing this light from entering the eye. This could potentially be a game-changer, and allow us to protect our future vision and that of our children. Make sure to ask us about this new technology and how to protect your children today!
