Swimming goggles includes a frame body, lenses, buckles disposed at opposite end portions of the frame body, and a head strap passed through the buckles. The frame body forms shielding portions at outer sides of the frame body. The buckles have bases and operating devices being shielded by the shielding portions. The operating devices are operated through the shielding portions so as to adjust the head strap and prevent a wearer's hair from being snapped and provide a comfort wearing.
