Abstract

A pair of spectacles has lenses (1, 2) that are connected to one another by a bridge element (3). The sides (6) are connected to the lenses (1, 2) by holding elements (5). The holding elements (5) and the bridge element (3) are preferably produced from flexible wire. The bridge element (3) and the holding elements (5) are connected to the two lenses (1, 2) by corresponding angled portions. A holding portion and a pin portion connect with the lenses (1, 2). The pin portion is accommodated in a through-bore of the lenses (1, 2). The holding portion is accommodated in a respective slot of the lens. Variations are possible by providing a simple plug-in connection allowing a selection to be made from a modular system, which enables the purchaser to assemble his/her own individual pair of spectacles.
