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 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
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.
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 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.
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.
