Swimming goggles include a frame body, lenses received in the frame body, and buckles assembled on left and right sides of the frame body. Each buckle has a first cover and a second cover assembled together, and a manipulation element assembled between the first cover and the second cover. The manipulation element has a base bar, a pressing plate formed on an end of the base bar, and two control arms integrally formed on an opposite end of the base bar. Flexible branches respectively extend from the two control arms, and further connect with the base bar. When the free ends of the two control arms are pressed, the branches are pressed and deformed, the base bar being forced to move the pressing plate to a side with an end of the pressing plate as a fulcrum, whereby the pressing plate disengages from the groove of the head strap.
