The future right in front of your eyes

uvex revolutionises bike glasses with a trend-setting glass technology that adapts to rapidly changing lighting conditions automatically or with the press of a button. This is made possible by a laminate of liquid crystals with electrochromatic activation through by a photocell light sensor. It reacts to the current intensity of light and regulates the tint of the glass in a split second. The uvex variotronic is available as the Sports Shield for cyclists, and as the full frame version optimized for mountain bikers.

Sudden blindness in a dark tunnel on the speedy downhill race? Stopping to change glasses because all at once, the trail has disappeared into the dusky pine forest? Or simply don´t want to carry a change of glasses? The revolutionary high tech development by uvex is the solution: In just the blink of an eye, the new uvex variotronic ff sports glasses adapt the tint of the glasses to the lighting conditions of the environment. This is made possible by the interaction of integrated light sensor with a specifically developed liquid crystal foil with electrochromatic activation that tints or clears the glasses in a matter of seconds, automatically or manually by pressing a button. The light setting has a light transmission of 64%, while the tinted glass only allows 16% light to pass through. The advantage is clear to see: The technology provides you with more safety and self-confidence in demanding situations and enables top performances even with changing light conditions. The variotronic ff bike glasses are powered by a rechargeable, integrated accumulator with 50h operating duration. The revolutionary etint glass technology is part of an exclusive cooperation between uvex and the US-specialist AlphaMicron.
