Abstract
An eyeglass frame has rims or surrounds at least locally made from a relatively rigid material. They have in transverse cross-section over at least part of their length a U-shape profile with a median part and side flanges. A strip of relatively flexible material is associated with each rim or surround and is disposed between it and the respective lens. The median part of the profile of the rims or surrounds has an increased thickness in its median area.
