New lenses improve vision while driving

The assertion sts from a series of user tests on the lenses conducted over four weeks by German inspection and product certification business TÜV Rheinland.  The testers – all progressive lens wearers aged between 50–69 – participated in a series of practical tests followed by an extensive questionnaire.The lenses scored a user acceptance rating of 1.7 (on a scale of 5–1) after having its adaptation period, field of vision, glare, contrast, colour perception and cleanability measured.Practical tests involved trialling vision at all distances without deliberate head movents, the perception of the dashboard, GPS and mirror, and also vision when parking. Reduction of glare from traffic and the environment in daylight, darkness, sun and rain was also tested, as was the ability to see in different levels of contrast such as unlit objects at dusk.According to company information, the combination of a special 12% filter tint and a prium anti-reflective coating reduces the dazzling effect of lights at night and minimises annoying and distracting reflections to improve contrast during the day. It also considers the higher order aberrations when calculating the lens and matches the fields of vision of both right and left lenses for undisturbed, three-dimensional vision.The Rodenstock Road range of products was launched in Australia this year.More reading: New driving-optimised lens on the marketView Showroom: Rodenstock
