发明名称 Eyeglass flotation apparatus
摘要 A temple mounted flotation device for eyeglasses is detachably attached for use during water related activities to prevent sinking and loss of the eyeglasses. The location of mounting in combination with the shape of the flotation device(s) affords lateral shading of the eye. The mounting structure permits alternative attachment of the flotation device to a head or neck band secured to the glasses.
