Here you get background information on spectacle lenses: Basics of ophthalmic optics, surface geometry and progressive lenses, lens materials, lens production and coatings.
Modern spectacle lens coatings, such as DuraVision® Platinum from ZEISS, provide great benefits thanks to their optimised hardness properties. However, caring for and cleaning the lenses correctly is very important for everyone who wears spectacles. This is because no optical equipment is exposed to the same mechanical strains and environmental influences as spectacle lenses.
Why is caring for spectacle lenses so important?
The pre-moistened, micro-fine tissue from ZEISS ensures effective and fast spectacle cleaning when you are out and about. Extensive testing by independent institutions (COLTS) show that it has better cleaning performance than ten alternative products - with no scratching or strain to the lens. The wipes have an exceptionally fine structure to ensure exceptionally gentle cleaning of all spectacle lenses, even with high quality coatings. It is pre-moistened with a unique combination of two active agents which are also used for medical equipment cleaning. These harmless agents are free from aggressive cleaning substances and artificial fragrances. And the best thing is that the ZEISS lens cleaning wipes can also be used for cleaning all types of sensitive optical surfaces (e. g. LCD displays, smartphones, tablet PCs, laptops, mobile phones etc.) easily and with no streaks.
Tests by COLTS, an international leading quality test laboratory within the optics industry, have shown that its cleaning performance is the most effective compared to ten alternative lens wipes – it cleans gently without causing scratches.
More gentle: the surface and coating of prescription lenses remain in sound condition even during a long-term test.*
More thorough: no other tested lens cleaner removes dirt as effectively.
