Swimming goggles includes left and right frames integrally formed together, a connecting element for interconnecting the left and right frames, protection pads, lenses installed in the left and right frames, buckles integrally formed on side portions of the left and right frames, and a head strap being movably connected with the buckles. Each of the buckles has a main body which is disposed on and integrally formed with the corresponding side portion of the left/right frame. More specifically, the buckles are capable of forming a part of the lenses, or a part of the left and right frames. Additionally, the main body is defined with a through hole for simplifying the structure of the swimming goggles and for making assembly of the swimming goggles less difficult, and further for efficiently reducing a cost for assembly of the swimming goggles.
