Abstract: A component for a lens module is selected from a group consisting of a lens barrel, an optical lens, a pressure ring, and a spacer ring. The component includes: a component surface, a flat region located on the component surface, and a microstructure region located on the component surface and adjacent to the flat region. Relative to the flat region, the microstructure region includes a plurality of convex portions and a plurality of concave portions. The convex portions are in a shape of a cone. Any area of 0.1 mm*0.1 mm in the microstructure region has n convex portions, where n?50.
