The axis specifies the angle of the cornea curvature. This value ranges between 0° to 180° and determines in which angle the lens is inserted into the frame.
The cylinder of a lens corrects a cornea curvature (astigmatism). The strength of the cylinder value is given in dioptres with a negative sign.
The spherical value on your glasses pass shows the dioptre value. The term is derived from a sphere, the geometric term for a ball. Therefore, it is also shown symbolically with a small circle.
It is short for Eye Lens Technology: EyeLT® is a new
technology in Rodenstock's lens manufacturing that has
been registered for a patent. Something that was considered to be
undoable has been possible since 2011 thanks to EyeLT®: up to 40%
better near vision for people who wear progressive glasses – a
milestone in the history of progressive lens technology.
The optician carries out a special near vision test with the customer for this. The eye is measured completely automatically and with high precision with the DNEye® Scanner, a new and innovative measuring device. Together with the results of the regular eye measurement, all this additional information is sent with the order to Rodenstock and we make the best possible lens from it. In short, the glasses wearer can exploit his individual vision potential by 100%.
As soon as you are no longer wearing your glasses, the best thing is to put them in a hard shell case. If you don't have a case, then always keep them in a safe location with the lens side up.
Unfortunately not. Lenses are not just one pane of glass or plastic, rather a complex system of layers for antireflection, tinting and other additional functions. Therefore "polishing out" scratches doesn't work. Scratched glasses should be replaced soon. The micro-fine scratches cause light to scatter. The eye has to correct constantly which leads to fatigue. Headaches may be the consequence.

*The guarantee and services may vary from country to country.
Your claims from the statutory guarantee are unaffected. Spare parts for your RODENSTOCK glasses will be available for several years after your purchase. In case of damage, you can hand in your glasses for repair and that way continue to use your lenses.
The hinges of glasses may indeed seem to have an inconsiderable affect, but as the only moving part in the glasses it fulfils two important tasks: First of all it provides the connection between the front of the glasses and the sides. The higher the quality of the manufacturing of the spring, the more reliable and longer lasting the entire spectacles. Secondly, the glasses hinge is decisively responsible for wearing comfort. Only if it is designed to be flexible and durable at the same time, does it make it possible to adjust the glasses to fit your head perfectly. The premium hinges from Rodenstock guarantee all of these characteristics. They are tested extensively for permanently good hinge movement, high adjustability and maximum durability.
