A pair of swimming goggles, includes left and right goggle frames, a connection bridge connected between the left and right goggle frames, a pair of buckles respectively attached to the left and right goggle frames opposite the connection bridge, and a head strap adjustably fastened to the buckles. Each goggle frame has outer and inner surfaces. A receiving hole is defined between the outer and inner surfaces of each goggle frame and receives a lens therein. Each buckle includes a base and a cover attached to the base. A chamber is cooperatively defined in the base and the cover and receives a shaft and a fastener therein. An entrance is defined between the base and the shaft. An exit is defined between the shaft and the cover. The fastener is adjacent to the shaft and includes a handle and an engagement protrusion. Each of free ends of the head strap extends into the entrance of the buckle, extends out of the exit of the buckle and abuts against the shaft. Each free end of the head strap selectively engages with the engagement protrusion of the buckle thereby fixing the head strap to the buckle. The handle is rotatable to disengage the engagement protrusion from the head strap whereby wearing length of the head strap is adjustable through moving the free ends of the head strap relative to the shaft.
