Description: This invention relates to a type of swimming goggles, or specifically an innovated structure of swimming goggles with a protective pad that encompasses two lens frames in one single space to provide wearing comfort and a wide. The two lens frames of conventional swimming goggles, regardless of a wide variety of structural modifications, are designed to cover two eye sockets separately. In other words, the conventional design of swimming goggles has been aimed at preventing leak by covering the eye sockets. Therefore, whether sponge type or sucker type, the protective pads are designed as separate units on the lens frames. When the conventional swimming goggles are worn by the user's face, there will be a suction force applied by the protective pads around the eye sockets, which would result in a certain degree of discomfort after an initial period of use under water. Furthermore, because of the limited area of lens of conventional swimming goggles, the field of vision is quite limited. The most direct way to improve the drawback of narrow field of vision in conventional swimming goggles, of course, is to enlarge the lens frames. But the integral structural of the entire swimming goggles will be changed after the lens frames are enlarged. Then, wearing comfort will be a new problem to be solved. US-A-5638552 discloses a diving face mask comprising a pair of lenses accommodated in lens holding portions of a protective pad and inner frames snapped in the lens holding portions. The main objective of this invention of swimming goggles is to provide a type of swimming goggles with wearing comfort and extensive field of vision.
