The concept of "ground lenses" comes from the optics. Optical glasses consists of lenses, which have a refracting effect as polished lenses and thus serve as a visual aid. Such optical lenses we have for reading glasses - but not for sunglasses.
All our sunglasses come with 100% UV protection. This means that all UVA and UVB and the dangerous UVC is filtered out by the lenses. In addition to 100% protection against UVA and UVB rays, the eyes are protected from the high-energy photons in the visible violet-blue range of the sunlight through our sunglasses by Filtral. Reading glasses have no UV protection.
Make sure that the glasses are stored with the glass side up to a suitable and fixed location so that they are stored safely and close at hand. For storage, get yourself a practical glasses case. Avoid exposing the glasses to extreme temperatures, such as e.g. quickly on the shelf in the car right under the windshield.
Clean the lenses with a soft cloth, preferably with a lens cloth made from microfiber. Do not use paper towels because they will scratch the lenses. Wash your glasses in warm water with mild soap and pat the glasses dry with a soft, lint-free cloth.
