The utility model discloses a frosted protection structure of an unconventional special spherical optical lens, which comprises an optical lens which has overall polishing treatment; a protective gluelayer is arranged at the position of the optical lens other than the position needing to be frosted. The frosted protection structure of the unconventional special spherical optical lens has reasonable structure; the clear distinction exists between the formed polished-surface and the formed frosted-surface; the polished-surface meets the finish requirements, and the particle size distribution ofthe frosted-surface is even.
