Abstract: Embodiments of the present invention disclose a photochromic lens module, a camera, and a terminal device. The photochromic lens module includes a lens module and a photochromic thin film. The lens module includes a first surface and a second surface. When the first surface is an incident surface, the second surface is a refractive surface; when the second surface is an incident surface, the first surface is a refractive surface. The photochromic thin film includes a first area and a second area. The photochromic thin film covers the first surface or the second surface. The first area uses a negative photochromic material, and the second area uses a positive photochromic material. By means of the embodiments of the present invention, a lens module can be effectively protected.

Abstract: This application discloses an optical lens, a camera module, and an electronic device. The optical lens includes a first lens group and a second lens group that are arranged from an object side to an image side, where the first lens group has positive focal power, the second lens group has negative focal power, and the first lens group and/or the second lens group are/is focusing lens groups/a focusing lens group. In a focusing process in which the optical lens switches from a long shot to a close-up shot, a spacing between the first lens group and the second lens group increases, and an effective focal length of the optical lens decreases. The optical lens satisfies a relational expression: F2/EFL>−5, where F2 is a focal length of the second lens group, and EFL is the effective focal length of the optical lens.

Abstract: An antireflection film includes a plurality of convex structures formed on a light transmission surface included in an optical waveguide. A maximum radial length of a surface that is of each convex structure and that is close to the light transmission surface is less than a minimum value of a visible light wavelength. The maximum radial length of each convex structure gradually decreases in a direction away from the light transmission surface. A height of each convex structure is greater than or equal to 310 nm. A distance between geometric centers of surfaces that are of two adjacent convex structures and that are close to the light transmission surface is less than or equal to 220 nm.
