Hallo, weiß jemand, was "flip eyewaer" auf Deutsch bedeutet?
Im folgenden Kontext geht es um die Anmeldung für einen Award:

[product] is probably the slimmest flip eyewear in the market today, catering to a huge population in their 40s who have Presbyopia. It is lightweight, aesthetically sound and also probably the first flip eyewear in the market with spring effect. Using 0.5mm thin high tensile stainless steel, the spring hinge is constructed as part of its top bar. The hinge is slim yet tough enough to support thick lenses in its flip-up position. It is consistent in reliability as compared to using screws, which will loosen over time and hence minimal maintenance is required. It is also recycle-friendly as parts can be disassembled without any tool.

Danke!
