A meta‐lens is an advanced flat optical device composed of artificial antennas. The amplitude, phase, and polarization of incident light can be engineered to satisfy the application requirements of meta‐lenses. Meta‐lenses can be designed to achieve a variety of functions, such as diffraction‐limited focusing, high focusing efficiency, and aberration correlation, which are useful in various application scenarios. This review focuses on the recent progress in meta‐lenses, from fundamentals to applications. The present challenges in this domain are summarized and future prospects are offered. The primary aim of this review is to provide the reader with a comprehensive understanding of meta‐lenses and potential inspiration for designing high‐performance meta‐lenses for feasible applications.
