Rodenstock has developed a new range of back-side progressive lenses, called Progressive Life Free, which it says will widen the field of vision, better matching the lens to the eye. Rodenstock also says the lenses increase quality and sharpness of vision and are less tiring, and have less deformation. The company, which reports a sales recovery since September, has also revamped its website, introducing new interactive elements and presenting a new corporate videoclip.
