Abstract: A device for interconnecting and pivoting two components of eyeglasses or protective elements for sports use. The device is constituted by a single flexible body that is detachably associable at at least one hole formed on one of the two components. The single body is provided with temporary engagement elements for the other one of the two components.
Abstract: A connecting device, particularly usable for eyeglasses, having two elements that are rotatably associable to each other and can be detachably connected to two separate components of the eyeglasses, at least one of the components being made of a material that cannot be welded to the device, such as aluminum. It is thus possible to produce aluminum or carbon fiber eyeglasses without welds.
Abstract: Multilayer lens particularly usable for sunglasses, having a main layer made of polycarbonate, cellulose acetate, or similar materials. A mirror reflecting layer is possibly coupled to the main layer or deposited thereon in vacuum by sublimation of appropriate substances, with the optional interposition of a layer of paint. The multilayer lens furthermore includes an outer layer that partially affects the outer surface of the lens. The lens may also include an inner antifogging layer that does not absorb moisture. This multilayer lens allows optimum vision to the user, eliminating or attenuating spurious incident rays at the lateral ends of the lens.
