Let's be clear: if these were “battle” sunglasses, the kind you buy and use for a season, then you have to throw them in the bin, then it almost wouldn't be worth the bother.
But when we talk about NRC sunglasses ( discover our collections ), we are talking about top-of-the-range models, all with very high-quality lenses (including the famous ZEISS , the only ones in the world to offer the same quality on sports and ophthalmic lenses), often subjected to anti-scratch, oil and water repellent and colorant treatments. In short, we are not talking about "simple" sunglasses, but of highly performing instruments , as well as classy aesthetic accessories .
In short, some care is required, because although NRC sunglasses are designed to be extremely resistant, some precautions are necessary to ensure that the optical performance remains unchanged.
Below we provide you with some easy tips for maintaining your NRC sunglasses. Really, it is a matter of a few simple attentions, but in the long run they can make a difference.
NRC Sunglasses: Lens Maintenance
Before explaining how to maintain the lenses of your sunglasses, let's start by briefly seeing how they are made. To simplify things, let's say that each treatment that is done to the lens to improve its performance and aesthetics (water repellency, scratch resistance, color, etc.) corresponds to a layer that is applied to the lens itself.
Now, all of these layers and treatments are designed to stand the test of time. And, in the case of scratch-resistant lenses, the lenses are equipped with an extra “shield” against damage (although they are still not invulnerable: I mean, if you put your mind to it, you can still scratch them).
The problem is that if you practice intense physical activity, especially in “difficult” environments, your lenses are subjected to prolonged stress due to the sweat, dust and sand that settle on them, and these layers can lose their effectiveness over time.
Keeping your glasses clean and preventing them from getting scratched is not just a matter of aesthetics: these scratches can affect the optical performance of the glasses themselves.
To prevent this from happening, you can “help” them with a series of small measures.
Cleaning lenses: our advice
After a day of sporting activity, our advice is, once you get home, to clean your glasses in the following way: rinse the lenses under running water , then make sure to dry them delicately , with the special microfibre cloth that comes with your NRC sunglasses.
Make sure , especially if you have been in a sandy environment, that the lenses are wet before cleaning them with the microfiber cloth. If there are grains of sand stuck to them, dry cleaning risks scratching them, with the consequences seen above.
If you want to add a “touch extra” to cleaning your glasses, make sure to only use specialized lens cleaners , such as those from Zeiss or those available from an optician. Avoid generic cleaners, as they may be too acidic, which can damage the lens layers.
As you can see, we are talking about a few, very simple steps, which will however contribute to preserving the quality of the lenses of your glasses.
After all, the best materials deserve special attention . And if you have any doubts about the maintenance of your NRC, do not hesitate to contact us .
