The eyewear described comprises a unitary arcuate lens having, at opposi te lateral sides thereof, a pair of detachable ear stems which are adapted to move from an inwardly folded position to an outwardly ear contacting position. Th e lens displays, at each lateral side, an opening and a stem connecting portio n that defines a hinge element forming an integral part of the lens. The proximal e nd portion of the ear stem defines a U-shaped recess which is engageable with t he hinge element. The recess is formed by a pair of resilient branches which, together with a constriction at the entry of the recess, enables a snap-in engagement and a snap-out disengagement of the ear stem to and from the lens. No additional component is required for this three-piece eyewear.</SDO AB>
