Unfortunately, no coating will mean never having to clean lenses again. However, lenses can be coated in such a way that impurities are less likely to adhere to the lens. CleanCoat makes the lens surface smooth, making it more difficult for dirt and dust to adhere. This simplifies lens care tremendously. The smoother the lens surface, the better.

Anti-reflective lenses can be recognized by the residual reflection. Regardless of the material used for the lenses, they have a characteristic colour when you hold the glasses at a slight angle against a white background. This is highly practical for the wearer: the optician can identify the anti-reflective coating and even offer the same high quality if a switch to another material is desired.

It’s all about protecting your eyes from the sun and glare when you’re outdoors. You and your optician can create your ideal sunglasses in terms of both colour and style. Coloured coatings for sunglasses are available for plastic and mineral lenses. A  wide selection of lens tints  – from single colours and gradient tints to bi-colour or even special tints for medical purposes – feature in the range of sunglasses from ZEISS. So your glasses, whether single vision or progressive lenses, will become your favourite accessory that also delivers first-class protection against the sun.

Another coating level with antistatic function can also help keep your glasses cleaner: fluff – from clothes, for example – adheres to these lenses much less.

Lenses without an anti-reflective coating have a great disadvantage:  There is a lot of visible reflection for the wearer. These reflections are particularly distracting on wet roads or when driving at night, but also when talking to someone as that person will see themselves reflected in your glasses rather than look at you.

Self-tinting lenses are a great idea for anyone who doesn’t want to change their glasses in the sun as these lenses incorporate a special technology which adapts to the sun – e.g.  PhotoFusion X by ZEISS

One thing’s for sure: Light has a considerable effect on managing our internal body clock, and thus our sleep patterns. Strong light in the early evening tells your body to stay awake for longer. When you look at the screen on your computer or another digital device, you subject your eyes to large quantities of blue light, causing such things as reduced contrast sensitivity. Focusing on a screen can also be strenuous for you and your eyes, and contribute to digital eye strain.

Just like a lotus leaf, water beads right off thanks to the wetting properties of the coating. A great bonus, particularly for anti-reflective lenses, because you’re more likely to notice dirt through improved reflection reduction than on lenses without such a coating.

Lens coatings act as a protective coating for your lenses, transforming modern plastic lenses into strong everyday objects. Unfortunately, lens coatings are often not given the importance they deserve when people purchase a pair of glasses, with wearers pretty much leaving this decision up to the optician. To make sure you’re well-prepared when it comes to anti-reflective, hard, CleanCoat and other coatings, we’ve put together a guide to help you find your way around the maze of coatings. After all, the choice is yours!

Le Avanguardie artistiche, in Europa, ebbero fine con la Prima Guerra Mondiale. Nel 1918 ebbe termine il conflitto e il mondo dell’arte in Europa rifiutò le sperimentazioni delle Avanguardie a favore del Ritorno all’ordine figurativo.

Formerly only needed when the sun was shining brightly, sunglasses with a  mirror coating  are now very much in vogue – and they’re available in your prescription! Talk to your optician today to see the wide range of colours and functions available for sunglass coatings.

Just ask your optician. Choosing the right coating also matters if you’re buying children’s glasses or a second pair for yourself – so don’t leave this important decision to chance!

So why not talk to your optician about the anti-reflective coating services on offer and about the coatings’ durability today! Ask for their tips about what you need to look out for to ensure your coating lasts as long as it ought to.

For plastic lenses (organic lenses) you definitely need a hard lacquer coating. While plastic lenses are easy to wear, the material used is softer and more prone to scratches than glass lenses (a.k.a. mineral lenses) – at least if untreated.

Con le sperimentazioni delle Avanguardie presero forma linguaggi totalmente rivoluzionari che portarono all’estremo il concetto di arte e oggetto artistico.

Avanguardie

Il termine avanguardia deriva dal linguaggio militare. Già al tempo con avanguardia si indicava il reparto che apriva la strada alla gran parte delle truppe verso il nemico. In campo artistico e culturale il termine Avanguardia, per estensione assunse il significato di guardare avanti, verso nuovi sviluppi della ricerca artistico-culturale.

A premium lens coating can help, one that’s integrated into the  ZEISS DriveSafe lenses. This reduces the subjective sensation of glare1 – e.g. from oncoming vehicles with LED or Xenon headlights – and effectively protects your lenses from both scratches and the adhesion of dirt particles.

Il fenomeno artistico delle Avanguardie storiche caratterizzò gli anni Dieci del Novecento. L’arte in questi anni fu in grande fermento e gli artisti sperimentarono un gran numero di linguaggi che sovvertirono la tradizione dell’arte figurativa.

Lenses can help protect your eyes against blue light thanks to a special filter, making it easier to work at a computer or use digital devices.

It is therefore advisable to opt for this lens coating, even for glasses you need for work or when watching TV.

Our vision has changed enormously now that we use digital devices such as smartphones, tablets, and modern illumination through LEDs and displays. We are subjected to more blue light than ever – all day long, in fact. High-energy blue light is also believed to have a negative impact on vision over the long term.

The residual reflection is usually green. The modern Duravion®  Premium lens Coating from ZEISS has an attractive, bluish residual reflection. The barely perceptible bluish residual reflection increases the amount of light the lens transmits to your eyes. And not only that – the blue is less visible to the eye. This means lenses with this residual reflection have the advantage of making your eyes look clearer to other people and have fewer reflections. Your eyes look more natural, almost as if you’re not wearing glasses at all.

Special coatings with a hard lacquer matched to the material not only enhance the scratch resistance of the lenses, they also ensure constant visual quality and extend durability. Thanks to the DuraVision®  Platinum coating, ZEISS offers a solution that is three times harder than the previous generation of hard (AR) coated plastic ZEISS lenses and 35% harder than AR coated mineral (glass) ZEISS lenses. This is made possible by the way ions seal the lens when the coating is applied.  Read on to find out more.
