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.
The easiest and most gentle way to clean your spectacles
is with some washing up liquid under running water. Afterwards, the
best thing is to rub the glasses with a microfiber cloth.
Please don't rub them with a T-shirt or paper tissue. Scratches cannot be removed from plastic or mineral glass lenses. Even if the flaw seems to be only cosmetic, light is scattered by the micro-fine scratches, which irritates the eye.
Your glasses would really appreciate intensive cleaning every 6 months by your Rodenstock optician partner. Just a few minutes in an ultrasound bath is enough to cause lenses and the frame to shine with their former glory.
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.
In order to ensure a high level of wearing comfort even in the long-term, the glasses must be adjusted to your head shape as accurately as possible. Rodenstock's development is based on more than 135 years of experience in how glasses fit. For that reason, glasses from Rodenstock are delivered anatomically pre-adjusted, and afterwards there are still numerous adjustment possibilities in the area of the nose pads, hinges and end pieces so that the optician can match the glasses individually to your head shape. That way eyewear from Rodenstock becomes the perfect glasses.
Since we work together exclusively with specialised optical businesses, there is unfortunately no possibility to handle sales or repairs directly with you as the end consumer. Use our store locator to find a Rodenstock optician partner close to you. He will be happy to help you.
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.
