Avoid very high temperatures, approximately as of 80°C. Neither lenses nor frames like to spend too much time in the sauna or on the dashboard of your car in the summer. In contrast, there are no known negative effects for use in the winter in temperatures that are below zero.

The trademark "R" on lenses from Rodenstock indicates to you that you have an original product from Rodenstock, which complies with the highest technical and functional requirements.

Besides the brand engraving, the lenses also have a so-called function engraving. The optician needs this for optimum alignment of the lens in front of the eye, and for clear correlation of the lenses. However, the engraving cannot be seen under normal light conditions.

Individual progressive lenses are personalised specifically for you and are therefore optimised. They are customised individually to your specific requirements and wearing habits. Far more individual parameters are incorporated into the manufacturing than for conventional lenses. They only take strengths into consideration for the lens according to a standard pattern. Individual progressive lenses such as Impression FreeSign^® 3 are therefore customised for your eyes. A great variety of data about your face and the frame that you select are measured with our 3D measurement terminal and taken into consideration in the manufacturing of these lenses. This means even greater visual comfort and up to one-hundred percent exploitation of your vision potential.

Yes! The size of the near vision zone is decisive for the reading comfort with progressive glasses. With Impression^® progressive lenses with EyeLT^®, it is particularly large for unrestricted reading enjoyment and clear vision in the intermediate and far range. That means you are much more flexible with progressive glasses than with simple reading glasses. Whether for near vision, intermediate vision or far vision, you just need one pair of glasses for any vision situation.
