Eyewear, and more particularly floating eyewear such as eyeglasses and/or sunglasses may include a frame, temples, and lenses wherein the frame and/or temples may be formed form the combination of a blowing agent and a polymer so as to render the eyewear floating. A method for making floating eyewear is also contemplated wherein a heat-activated blowing agent is dry-blended with a plastic resin to form a mixture which is loaded into a hopper coupled to a cylinder, after which the mixture is heated to a molten form, injected into a mold, cooled, and then later ejected from the mold.
