Abstract
The invention provides spectacles of the type without a surround, comprising a bridge interconnecting two lenses, and two hinged side arms, each side arm being mounted to pivot about a horizontal axis that is oblique, between a deployed position for use and a folded position against the inside surfaces of the lenses. In accordance with the invention, each side arm is connected to the corresponding lens via a hinge link of one-piece structure, said link having an inner portion fixed against the inside surface of the lens and prevented from turning relative thereto, and an outer portion offset laterally from said lens, with said side arm being hinged to the back of said outer portion via a terminal eyelet of the side arm.
