Abstract: Disclosed are an optical lens and a lens module. The optical lens comprises a first surface and a second surface arranged opposite to each other. In a region including the first surface and a first reference surface, the volume of a portion protruding relative to the first reference surface is a first protrusion volume, and the volume of a portion recessed relative to the first reference surface is a first recess volume. In a region including the second surface and a second reference surface, the volume of a portion protruding relative to the second reference surface is a second protrusion volume, and the volume of a portion recessed relative to the second reference surface is a second recess volume. A first volume is obtained by subtracting the first recess volume from the first protrusion volume. A second volume is obtained by subtracting the second protrusion volume from the second recess volume. The absolute difference between the first volume and the second volume is less than or equal to 0.15 mm  3 . The above arrangement can enhance the flowability of a material in a process of manufacturing an optical lens, such that the forming process is smooth, and the formed optical lens will be stable and have a more attractive appearance.
