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.
Mainly frames made of acetate and titanium are best suited
for people with nickel allergies. Both materials are hypoallergenic.
At the same time, all other materials used to make glasses comply
with the EU nickel directive. Rodenstock monitors compliance through
standardised quality checks.
Along with nearsightedness, farsightedness (hyperopia) is
one of the most common visual impairments. If you are farsighted,
then you can see well at long distances without glasses, but
everything is blurry and unclear up close. In most cases, the cause
is an eyeball that is too short (longitudinal hyperopia). The image
is created behind the retina and is not sharp. Just like
nearsightedness, farsightedness (myopia) is also measured in
dioptres. It can be compensated for optimally with Rodenstock lenses
with a plus effect – and you can once again fully utilise your
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.
Vision deteriorates in the near range with increasing age,
and books or letters have to be read with your arm extended. The
ageing process of the eye is responsible for this and the
deteriorating elasticity of the lens that goes along with it.
Progressive glasses are suitable for
compensating for presbyopia for smooth, clear vision at all
distances. At your workplace, you will benefit from special computer
glasses with Ergo® near comfort lenses.
