Plastic or mineral glass?
|
|
A spectacle lens is a miracle of science! It consists of a
material that has to be perfect: transparent, pure, clear and
homogeneous in structure. And made from a material which requires
the highest possible precision in manufacture and processing. A lens
should also offer UV protection without a tint and should be easy to
look after.
So which material is the right one
for you? This will depend on your individual requirements: Should
the spectacles be light, because you prefer filigree frames? Or do
you find ”low maintenance” and high strength more important? Plastic
or mineral glass - discover the difference here. |

Light and thin: plastic
|
|
| Plastic lenses are light in weight and permit the use of
extremely filigree frames. Special coats on the surface such as
Rodenstock Solitaire® prevent reflections and protect the lenses
against scratches. However, plastic lenses still require a little
more care than mineral glass lenses. |
|
Tough, but high in weight: mineral glass
|
|
| Some spectacle wearers still swear by the proven qualities
of glass lenses. As fragile as glass may appear, it is amazingly
tough and resistant. Advantages include the low care requirements
and the high scratch resistance; however, the somewhat higher weight
is a disadvantage. And despite their strength, mineral glass lenses
can splinter and break in extreme cases. |
