Extremely lightweight sunglasses with good fit and soft temple ends that provide secure support without pressing. The S version is the right place for my long face shape, people with a round face should rather take the normal version. The wraparound glasses cover the lateral sunlight from beautiful, which is a drawback in many conventional glasses. Only at the very edge of some distortion is visible through the prominent bulge, but is still acceptable. The Level 3 tint is too dark, even less would be no proper sunglasses more. I use them mainly in the car where I want to wear no real glass glasses, in the event of an accident (airbags). I have another, very similar Swiss Eye glasses for about 6 years. Although entirely of plastic, they are not fragile or prone to scratches. The only Minuspukt is maybe that they are also folded still relatively large, compared with straight sunglasses. For the shirt pocket a bit inconvenient. The glasses come with a protective bag made of microfiber, which you can use as a cleaning cloth, ziehmlich practical.
