How should I take care of my prescription eyeglass lenses?

If you take good care of your glasses, you'll find it easier to keep everything in focus. Here are our tips.

Today's modern prescription eyeglass lenses really are a miracle of technology. If you want to enjoy your glasses for as long as possible, it's not only important to take good care of them. It's also important to protect them from damage caused by harmful external factors. 

Whether you're near-sighted or far-sighted, the right prescription eyeglass lenses make sharp vision easy. You'll be able to enjoy your glasses for many years if you have them specially adapted to suit your individual prescription by an eye care professional. But one important condition of this is that you'll need to take proper care of your prescription eyeglass lenses, and handle them sensibly. This is because improper handling of technically advanced modern eyeglasses can lead to the lenses becoming scratched or damaged.

This is particularly true in the case of plastic lenses. High-tech coatings do offer a maximum level of protection, even for very thin and fragile plastic lenses, but they can still be scratched. The result is that the lenses become less clear, it gets more difficult to see through them, and vision becomes less sharp. But this doesn't have to happen. Here are some helpful tips:

Microfiber lens cloths

For routine care of your glasses, it's important to use only lens cloths made from microfibers. They are available from any eye care practice. Dust and dirt cling to them. Wiping with a microfiber cloth, also known as dry cleaning, removes particles of dirt and dust and can be carried out at any time, even when you're on the move. If the prescription eyeglass lenses are more heavily soiled, the first step you should take is to wash them in lukewarm water. A drop of dishwashing liquid makes the cleaning process even more effective. But be careful: don't use oily soaps. Oily deposits may be left behind on the lenses, causing irritating smears. Lens cleaner sprays, available from eye care professionals, are also very effective. After being cleaned with the spray, the lenses can then be wiped dry with a lens cloth.

The alternative for on the go:

Clean your eyeglasses quickly and gently

Did you know about the pre-moistened lens cleaning wipes from ZEISS? Individually packaged, the wipes are easy to use in any situation. They are pre-moistened with a special combination of two active agents, and free from aggressive cleaning substances and artificial fragrances.  

Your clothes aren't a suitable replacement for a lens cloth

Prescription eyeglass lenses don't get along well with t-shirts, sweaters, and other fabrics. So even if it's the easiest, most tempting option, it's never a good idea to wipe your glasses with your clothes. The risk of scratching the prescription eyeglass lenses is too high. The fact is that scratches still can't be buffed out of lenses, so the damage caused to them will be permanent.

Now and again, it's worth making a trip to an eye care professional to have your glasses cleaned. The eye care professional has special equipment which can be used to clean glasses thoroughly and gently. The most important of these is the ultrasonic bath. In this process, the glasses are placed in a special container. In the space of a few minutes, the glasses are cleaned extremely efficiently using ultrasonic vibrations. The process cleans not only the lenses, but also the frame. Devices for use at home have now become available. If you want to buy one, you would be well advised to visit a specialist store for expert advice. This is because the best cleaning results can only be achieved by machines which operate at a very high vibration frequency.

Beware of high and low temperatures

As well as taking proper routine care of your glasses, it's also important to handle them properly. It seems obvious, but one step is the most important in protecting your glasses: never place them face down on the lenses. Instead, fold them up and put them down so they rest on the frame. To avoid the annoyance of searching for your glasses, it is advisable to always put them down in the same place. Then they'll always be there, making it easy to find them. It's worth pointing out at this stage that seats, chairs, and sofas are completely unsuitable places to put glasses. It's just too easy to sit on them by accident.

If you aren't going to be wearing your glasses for a long time, such as during the night, it's best to store them in a suitable eyeglass case. This advice is especially relevant for dog owners. You might find that your four-legged friend enjoys chewing the frames, and even the lenses, of your glasses. The result won't just be annoying for you; it could also be dangerous for your dog.

Something else that glasses and prescription eyeglass lenses really don't like is high temperatures. So whether it's summer or winter, you should never leave your glasses out in direct sunlight. In particular, you should avoid leaving them on the dashboard of your car. Radiators won't do your glasses any good either. And if you visit a sauna, it's best if your glasses don't join you. The cold months of the year can also damage glasses, which can warp if they are exposed to very cold temperatures. So it's not a good idea to leave them in your car overnight in winter.

In general, a high-quality prescription eyeglass lens coating can make your life, and your glasses cleaning routine, much easier. A ZEISS lens coating, for example, makes your prescription eyeglass lenses water- and dirt-repellent and gives them antistatic properties. In prescription eyeglass lenses with a ZEISS coating, the prescription eyeglass lens surface is smoothed to such an extent by the coating that dirt particles or droplets of water cannot cling to it, and are shed like from a lotus leaf. Because of this, prescription eyeglass lenses which have received this treatment are easier to clean. They also need to be cleaned less frequently. Even greasy fingerprints can easily be removed from the prescription eyeglass lenses.
