Filter 30%+ of Blue Light
Our blue light glasses help filter your eyes from potentially harmful blue light* emitted by digital screens. The approximate percentage of blue light reduced can vary by style, and is approximately 30% unless otherwise stated in the product description.
Combat Computer Vision Syndrome
Computer Vision Syndrome, also called Digital Eye Strain, is a group of symptoms that can appear after prolonged exposure to the blue light emitted from digital devices. Because our eyes have difficulty focusing on blue light, we experience symptoms including eye strain, headaches, dry eyes, blurred vision, and difficulty sleeping.
Near-Clear Lenses
Our blue light filter lenses are near-clear, which means you can keep your eyes focused without distorting the colors you see.
Reduce Glare
Blue light lenses reduce glare and reflections from screens and overhead lights that can cause eye strain.
Blue light is a type of high-energy light in the visible light spectrum. You can be exposed to blue light from both natural and artificial sources. The sun is a natural source of beneficial blue light, and it helps regulate our body's natural sleep cycle. Artificial sources of blue light in the 415-455 nanometer range of the visible light spectrum, however, can be harmful with prolonged exposure. Artificial sources of blue light include digital screens, electronic devices, and fluorescent and LED lighting.
Any digital device with a visual screen emits blue light, including computers, laptops, tablets, smartphones, e-readers, and TVs. You're at risk for symptoms of Computer Vision Syndrome if you use any of these devices for more than two hours per day, which many of us do before we even leave for work! If you spend significant amounts of time in front of a computer at work, reading on a tablet at home, or watching TV, these blue light blocking* readers are your key to happy eyes.
Your power for computer or blue light readers may be different than your normal reading power. The strength of your blue light reading glasses is determined by the distance between you and your computer or device. To find your average distance, use a ruler to measure from the bridge of your nose to your screen at your usual viewing distance. Then see the image above to make adjustments to your standard reading power.
*Potentially harmful blue light refers to the 415-455 nanometer range of the visible light spectrum. The percentage represents the average amount of potentially harmful blue light filtered at 5 nanometer increments in this range. Covered under U.S. Pat. No. 8,360,574.
