Coatings on eyeglass lenses are delicate. Even an unsuitable cleaning cloth can cause fine mechanical damage over the course of months, which only becomes noticeable when the lenses become dull or the coating starts to peel off. The cleaning solution alone is rarely the decisive factor here; rather, it is primarily the quality of the microfiber cloth used.

The question of correct cleaning is of central importance for opticians. Because if you want to protect lenses, you need to take a close look at the material compatibility of cleaning agents for lenses. Modern lenses are no longer simply made of plastic or mineral glass. They have multiple coatings, hard layers, anti-reflective coatings and often additional functional layers. And it is precisely these that react sensitively to unsuitable cleaning agents.

The question of possible damage to the coating of hearing aids caused by cleaning products is a concern for many hearing care professionals. Because hearing systems are high-quality medical products. And their surfaces are technically sensitive. This is why people often research how hearing aids can be cleaned without endangering the material or coating.

Free customer loyalty for opticians and hearing care professionals is becoming increasingly important. Because markets are changing. And customers compare more frequently. This is why many consumers are switching providers more quickly than before.

Many owner-managed specialist stores are increasingly concerned with the Medical Devices Ordinance for Ophthalmic Opticians and the Medical Devices Ordinance for Hearing Aid Acousticians. The reason is clear. Spectacles and hearing aids are considered medical devices. They are therefore subject to strict legal requirements. And that is why opticians and hearing aid specialists are regularly inspected.

Many opticians wonder whether alcohol in a spectacle cleaning agent can damage frames and lenses. And this question is justified, as many lens and frame manufacturers recommend cleaning glasses with cleaning agents without alcohol.
