Non-corrective eyewear such as sunglasses, skiing goggles and diving masks can be easily and economically made to correct eyesight with a corrective eyewear attachment that is aesthetically pleasing. The attachment may include a corrective nose piece connector and/or a rotatable lens. The rotatable lens makes it more economical to have prefabricated corrective lenses that requires a particular lens orientation such as when the corrective lens corrects for an astigmatism.
