LightPro Technology by ZEISS Sunlens offers glare reduction and at the same time, allows for the transmission of the carrier portion of light that helps to define vision in different sourroundings or cirumstances.

Light reflected from a glossy surface is mostly polarized. It can generate reflection or glare depending on different conditions such as light intensity, time of day and environment. Intense glare can be blinding, uncomfortable and it can prevent good vision outdoors. However, polarized light also helps to provide a natural and complete perception of the surroundings. In fact, light reflected off an object or a surface is what enables an accurate perception of it. Potential hazards such as ice patches, metallic objects or asphalt become perceptible to the viewer because it reflects light in a specific way.

Reducing blinding glare and enhancing natural vision

ZEISS LightPro Technology for plano sun lenses offers the glare free vision of a polarized lens and the natural perception of standard lenses.

Standard polarized lenses filter up to 99 percent of reflected light. But such lenses block parts of the visual information which may lead to a lack of depth and contrast perception. In situations where sun and shade alternate, the lenses may appear too dark.

LightPro Technology, however, filters the part of the reflected light that generates visual disturbance but at the same time, preserves the so-called positive reflection which is inherent in polarized light and transports visual information. By reducing environment-specific predominant light colors, ZEISS LightPro lenses provide a more balanced color perception with the ability to see shadow and contrast that would otherwise be indistinguishable. As a result, blinding glare is reduced in intensity, but natural vision and terrain details are enhanced.
The balanced filtering of polarized light with LightPro Technology also allows the wearer to read displays of digital devices, LCD screens, smartphones or tablets. This is particularly important while driving, as the digital dashboard information or navigation systems panel should remain visible. When it comes to playing sports, LightPro Technology also allows for a clear view of smart watches or GPS devices.

ZEISS has developed LightPro Technology, a new plano sun lens solution that filters only the right amount of polarized light, to cut annoying glare while preserving visual information.

ZEISS Sunlens is the division of the ZEISS Group dedicated to the research, development, and production of prescription-free high-quality sunglass lenses to offer protection from the sun's rays as well as superior optical performance.
