Swimming goggles include a pair of lenses, a pair of lens frame members each supporting one of the lenses, a bridge belt by which respective inner edges of the lens frame members are connected to each other, and a head band extending between respective outer edges of the lens frame members. The lens frame members are provided adjacent their inner edges with coupling means adapted for releasably receiving stoppers formed on the bridge belt so that a distance between the inner edges can be adjusted. The bridge belt is formed on its inner surface with pairs of the stoppers arranged symmetrically with a center line longitudinally dividing the bridge belt in two. The bridge belt is made of a plastically deformable material and a portion of the bridge belt defined between a pair of the symmetrically arranged stoppers is formed on its inner surface with grooves extending transversely of the bridge belt.
