Abstract: A liquid crystal lens, a method of controlling a liquid crystal lens and liquid crystal glasses are provided. The liquid crystal lens includes a liquid crystal layer; and an electrode structure. The electrode structure includes: a first sector region; a second sector region; at least two first annular sector electrodes in the first sector region; and at least two second annular sector electrodes in the second sector region. The electrode structure is configured to: in response to voltages applied to the at least two first annular sector electrodes, configure the liquid crystal molecules as a first Fresnel element; and in response to voltages applied to the at least two second annular sector electrodes, configure the liquid crystal molecules as a second Fresnel element, the second Fresnel element being different from the first Fresnel element.
