We get a lot of questions about our DigiTec® lens technology. Here are some of the questions we get the most.
What is digital eye strain?
Also known as computer vision syndrome (CVS), digital eye strain describes the physical discomfort people experience after using digital devices for more than 2 hours per day. Digital screens emit a significant amount of blue light (also called high-energy visible light), and according to the Vision Council, about 80% of American adults use digital devices for two or more hours per day, and 59% of adults report experiencing one or more symptoms of eye strain, including: tired eyes, headaches, blurred vision, dry eyes, and neck or shoulder pain.
What is blue light?
Blue light is part of the visible light spectrum, which includes wavelengths between 380-780 nm. Invisible light--like ultraviolet light and infrared light--are below this range. Blue light wavelengths range from 400-465 nm and the most harmful rays are between 415-455nm.
Though too much blue light can be harmful, it's important to note that blue light isn't all bad--in fact, blue light is critical for our vision! It occurs naturally in sunlight and plays an important role in our vision and determining our sleep-wake cycles.
But computers, smart phones, TV, LED lights and fluorescent lights all emit blue light too, and excessive exposure to blue light in the short term can disrupt your circadian rhythm and result in digital eye strain. In the longer term, excessive exposure to blue light may damage the retina.
What is DigiTec® technology?
Developed with our exclusive "natural light" Deposition Lens Technology, DigiTec® lenses improve contrast and filter out the scattered blue light that can lead to digital eye strain. At 410 nm, DigiTec® lenses block more than 85% of harmful, high-intensity blue light. Equipped with an anti-reflective coating, these non-polarized lenses also cut glare.
Who should use DigiTec® lenses?
If your job or hobbies include regularly using digital devices, you're a great candidate for DigiTec®--and bound to notice the results. Our loyal DigiTec® customers include office professionals, gamers, graphic designers, video editors, writers, and many more.

"This year, I finally decided to try my first pair of blue light filtering glasses and it made a world of difference. Combined with extra blinking, my eye strain all but disappeared. If I was conscientious about wearing them, I even found myself falling asleep easier." GameSpace
"On the first night, I immediately noticed it was much easier to fall asleep, and my quality of sleep was overall better... It's incredible how much more relaxed and at ease my eyes are even after 12+ hour work days.
