How to go to glasses emerald

This will make the glasses really clean again

All dirt that collects on the glasses during the day is detrimental to a clear view in two ways. On the one hand, the greasy, dirty particles immediately ensure that vision becomes milky and vision is impaired as a result. On the other hand, they can ensure that the glass is downright damaged. If the dirt particles are not cleaned or cleaned incorrectly, they scratch the plastic surface of the glasses. The microscopic scratches that occur can ensure that the light is scattered. Headaches and rapid eye fatigue can be the result. In contrast to the car paintwork, for example, the scratches cannot be removed again:

Most glasses these days are made of plastic. You can't polish anything away, it will only make the scratches worse.

With these products you can damage your glasses when cleaning

The micro-scratchers are favored if the wrong cleaning agents are used. Paper tissues, facial tissues or kitchen rolls, for example, can contain wood fibers that also scratch the surface. In addition, the dirt particles on the glasses are only pushed back and forth and not picked up. The effect is then similar to that of sandpaper: the surface is roughened and scratches occur. The same thing happens when the glasses are quickly cleaned on the T-shirt or tie. Chemical cleaning agents such as glass cleaners contain alcohol. This can attack the plastic material of the glasses. Alcohol is also found in many cheap, damp eyeglass cleaning wipes. A test by the Ernst Abbe University in Jena on behalf of the NDR also showed that many of the cleaning cloths only smear grease soiling, but do not clean the glasses effectively.

How to clean your glasses properly

To clean the glasses, water, soap or shampoo and a microfiber cloth are ideal. It is important to hold the glasses by the edges of the lens as much as possible when cleaning and to work with little pressure so that they cannot break. In the first step, loose dirt particles should be blown off the glasses or gently wiped away with a clean microfiber cloth. Then the glasses are rinsed under running water. The water should be lukewarm so that the dirt particles are washed off well. To loosen dirt and grease deposits, optician Michelis recommends rubbing liquid soap or shampoo on rinsed, wet glasses:

We used to recommend dishwashing detergent, but these days it contains chemicals that are too harsh that could damage your glasses. Things made to cleanse the body are gentle enough for our glasses.

It is important, however, that the selected cleaning agent does not contain any lipid-replenishing substances. They are good for the skin, but bad for clear glasses, because streaks remain.

The temples and the nose bridge should also be cleaned, because this is where sebum and sweat residues from the skin collect. The glasses can then be dried with a microfiber cloth or a soft, lint-free cotton cloth.

It does not matter whether you use the small microfiber cloth from the optician or a large one, what is important: It should be clean and only be used for the glasses.

Microfiber or glasses cloths should be washed regularly in the washing machine at 40 degrees without fabric softener.

If it has to be done quickly: use cleaning spray

In the office or on the go, it is more difficult to thoroughly clean the glasses this way. Cleaning sprays are a good alternative to damp cleaning wipes. For example, they can be applied to the glasses cleaning cloths by the optician and also clean the glasses thoroughly and gently.

However, there is always the risk that you will rub coarse dirt or dust particles into the glasses if you do not rinse the glasses with running water. So if it somehow works, wait until you have the opportunity to clean the glasses with water. "

Have them cleaned regularly in the ultrasound machine

Opticians use special ultrasound devices for cleaning. The glasses are also cleaned with water and a special cleaning concentrate, but the vibrations of the ultrasound create bubbles that remove all dirt effectively and without friction. In addition, with the ultrasound device, every crack in the glasses, no matter how small, is thoroughly cleaned - the device is therefore much more effective than normal cleaning, especially around the edges of the glasses. Most opticians do the ultrasonic cleaning for free. If you have several glasses wearers in your family or do not want to go to the optician all the time to do this thorough cleaning, it could be worthwhile to buy an ultrasound device yourself. It costs around 30 to 40 euros.
