Abstract：Liquid crystal Fresnel lenses（LCFLs），as electrically tunable optical elements，have demonstrated significant application potential in recent years in fields such as augmented reality （AR）/ virtual reality（VR） and adaptive optics，owing to their compact structure，tunable focal length，and capacityfor large apertures. This paper provides a systematic review of the technical principles and current development status of LCFLs，with a particular focus on their phase modulation mechanisms and methods for controlling optical properties.By comparing structural diffrences with conventional refractive lenses， thecritical role of liquid crystal anisotropy and electric field response characteristics in achieving multi-level phase profile design is summarized.Furthermore，application cases of this technology in AR/VR near-eye displays，auto-stereoscopic display systems，and adaptive optics are discussed. Finally，prospects for the future development of LCFLs are presented.
