Mineral glass was considered to be the premium material
for manufacturing lenses for a long time. However, times change.
Today, lenses are made almost exclusively of high-tech plastics,
which are superior to mineral glass in almost all ways.
Lenses made of plastic are lightweights and can be
manufactured very thin. That increases the aesthetics and wearing
comfort for the glasses wearer. In addition, plastic lenses are
absolutely clear, robust and the colour is stable.
The overriding industry standards apply to lenses from all
manufacturers. However, they are not sufficient, because for the
System of Better Vision, exclusively high-quality materials and
precision manufacturing are used. For that reason, Rodenstock
developed its own standards that guarantee the highest quality in
every stage of development and production. This includes strict
material tests, extensive compatibility studies and quality tests
before each individual product is shipped. We offer everything from
a single source, from the research and development right up to
manufacturing the lenses.
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
