ZEISS BlueGuard: The Latest Generation of Blue Light Protection for more Visual Comfort and Aesthetics

The use of electronic devices, whether in small or large format, changes viewing habits. With ZEISS BlueGuard, a new generation of blue light blocking lenses is introduced to the market addressing today's technology and media use in the context of the "new normal". The blue light blocking properties are now incorporated into the lens material itself. As a result, ZEISS BlueGuard Lenses provide excellent lens clarity as well as the blocking of up to 40 percent of the potentially harmful and irritating blue light in the wavelength between 400 and 455 nanometer (nm)1, which is known to be linked to digital eye strain.


Preventing digital eye strain when using digital devices

"Digital screens and indoor LED lighting emit a higher proportion of blue light than traditional incandescent or halogen-type light bulbs. In addition, we are often exposed to this blue light for long periods of time, often until late at night at short visual distances. This combination of excessive near work and chromatic intraocular challenges linked to blue light strains the eye muscles and can contribute to visual discomfort and asthenopic symptoms associated with digital eye strain," explains Dr. Christian Lappe, Director Technical Communication at ZEISS. BlueGuard Lenses from ZEISS block a part of the blue light spectrum that could exacerbate symptoms of digital eye strain, including tired eyes, blurred vision, sleep disturbances and dry or irritated eyes. The positive properties of blue light, ranging from about 455 to 500 nm, remain unaffected. "By reducing glare, our new material-based approach contributes to preventing strain on the eyes and provides comfortable, relaxed vision and increased contrast," he adds. All in all, ZEISS BlueGuard Lenses are designed for all-day use and offer an additional comfort aspect that reduces eye strain and allows relaxed working conditions.
