What offers a polarized lens and when should we choose a contrast enhanced lens? The new Rodenstock Sunwear App illustrates the advantages of Rodenstock Polarized lenses and Rodenstock SunContrast and shows the specialities compared against standard sunglasses or without protection. The differences are represented very clearly to the users through five distinct landscapes (i.e. street traffic, water, snow, village street, golf course). By the easy movement of the respective Rodenstock demo lens the observer gets the opportunity to see each single area of the landscape and to experience the advantages of using Rodenstock Sunwear. Apart from that there is some useful information about the appropriate activities and the available colours.
