ABSTRACT:
An eyeglass frame has a pair of at least limitedly flexible upper arms and a pair of respective at least limitedly flexible lower arms. Each arm has an inner end and an outer end and a bridge interconnects the inner ends so that each upper arm forms with the respective lower arm to a respective side of the bridge a seat for a lens. Respective pairs of elastically deformable elements have front ends fixed to the outer ends of the arms and rear ends fixed to a respective temple support with each pair of elements biasing the respective upper and lower arm toward each other so that the lens is gripped elastically in the seat. A respective temple is pivoted on each of the temple supports. A pair of eyeglasses is assembled from such a frame and a pair of lenses by first displacing each upper arm away from the respective lower arm with elastic deformation of the respective elements until the respective seats are wide enough to accept a respective lens. Then the respective lenses are figged to the widened seats and the upper and lower arms are released so that same elastically engage edges of the lenses while leaving a gap between outer ends of the upper and lower arms.
