1. An optical lens, comprising a light incident portion and a light emergent portion, wherein the light incident portion is provided with a first single-directional alignment surface, and the light emergent portion is provided with a second single-directional alignment surface, an alignment direction of the first single-directional alignment surface and an alignment direction of the second single-directional alignment surface are perpendicular to each other, and the first single-directional alignment surface and the second single-directional alignment surface jointly form a focal point or a focus area of the optical lens,
wherein the first single-directional alignment surface and the second single-directional alignment surface cooperate with each other to make focal lengths on two sides of the optical lens different, so that an asymmetric light shape can be formed, wherein a length and a width of the asymmetric light shape are different.
