A spectacle structure for wear during active sports where eye protection is desired includes a protective panoramic or wrap-around frame and portions snugly engaging spaced parts of the head to support the frame on the head of a person. Lenses, such as prescription lenses, are fitted into the frame with removable transparent guard lenses thereover and spaces are provided for ventilation of the lenses and the person's eyes to aid in remedying condensation and discomfort.
