ABSTRACT:
A novel type of swimming goggles includes an improved means for receiving corrective lenses. The corrective lens forms the outermost face of the goggles and is easily insertable. The novel swimming goggles of this invention are inexpensive to manufacture. The lateral vision of the swimmer is improved due to the transparent sidewall construction of the goggles. A resilient gasket between the goggle socket and the face of the swimmer allows for a watertight seal therebetween.
