Rodenstock Spectacles philosophy:

• The eyes and the spectacle wearer are most important.

• Esthetics: thin, anti reflection coatings.

• High wearing comfort: light, easy to care.

• Perfectly matching to the physiology of the spectacle wearer: individual calculation and production.

What isImpressionILT ?

Impression ILT.

• The first backside progressive lens in the world, thatis only completely calculated and produced after theorder entry.

• All relevant individual data of the eyes, the head and the frame are taken into account.

• Tailor made for every individual spectacles wearer.

“I only wear what suits me”

By nature you are a unique individual. And Rodenstock makes sure that you have a unique visual experience combined with good looks.

They provide optimum vision and are as unique andindividual as your own face. We want you to wear only the spectacles that suit you.
