Thin and light


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.
