Abstract: A swimming goggle structure includes two frames, each having a lens seat defined by a raised wall formed thereon to support a lens. A loop-like lens securing member, is removably fit onto the raised wall of the frame to hold the lens on the lens seat of the frame. The raised wall has an inner surface on which a sideways-opened groove for supporting and holding the lens is provided and an outer side on which a circumferential shoulder is formed to support the loop-like lens securing member. The shoulder has a lateral groove recessed into and Co-extensive with the raised wall and the loop-like lens securing member has a corresponding inward-projecting rib receivable within the outer groove of the circumferential shoulder to removably hold the lens securing member on the lens seat so as to allow a user to replace the lens by oneself by removing the lens securing member from the raised wall of the frame.
