The invention provides a lens coating sleeve ring, wherein an upper cover and a lower cover of the lens coating sleeve ring have the same structure, the mold manufacturing cost is low, the use of an injection molding machine platform is reduced, furthermore, the upper cover and the lower cover can be exchanged in use, thereby shortening the manual operation time, and a positioning structure is arranged to ensure the combination precision of the upper cover and the lower cover. The lens coating sleeve ring comprises the upper cover and the lower cover, wherein the upper cover and the lower cover are components of the same structure, each of the components specifically comprises a peripheral frame and a central coating area, the peripheral frame is circumferentially arranged at the peripheryof the central coating area, the component comprises an exposed surface and an installation positioning surface, the installation positioning surface of the central coating area is concave relative to the installation positioning surface of the peripheral frame, the concave depth is a half of the thickness of a lens to be coated, a plurality of coating holes are distributed in a surface area corresponding to the central coating area in a rectangular array, a gap is reserved between the adjacent coating holes, and the peripheral frame is a rectangular frame.
