A pair of swimming goggles includes a frame made of plastic material and including a pair of rims each defining an engaging groove therein. Each of the rims includes an annular member extending inwardly from an inner periphery which defines the engaging groove and thus separating the engaging groove into an outer portion and an inner portion. A lens of rigid transparent material is received in the outer portion of each of the rims and has a first engaging member formed on a first side thereof. An engaging ring of rigid material is mounted in the inner portion of each of the rims and has a second engaging member on a first side thereof, in which one of each of the first engaging members and the second engaging members extends through the associated annular member to engage with one another. The lenses, the frame, and the engaging rings are fused together by ultrasonic waves, thereby forming an integral pair of swimming goggles.
