The present disclosure relates to a reflector lens structured life buoy, including a life buoy body. Several sections of lenses are arranged in the life buoy body. Each section of lens is of a curved cylinder structure. These lenses are distributed in a circular array by taking a center of the life buoy body as a center, so that these lenses are encircled to form a circular ring. Cross sections of all the sections of lenses in a radial direction are of a layered structure, and have dielectric constants that continuously change from 2 to 1 from the center to the outer layer. Reflection sheets are laid on circumferential surfaces of all the sections of lenses to form reflection sheet coverage regions and non-reflection sheet coverage regions on the circumferential surfaces of the lenses; surfaces of the reflection sheets fitted to the circumferential surfaces of the lenses are reflection surfaces.
