An optical defocus lens includes: a first lens layer and at least one liquid crystal lens layer, where the first lens layer is a concave lens, a convex lens, or a plano lens, a refractive index of liquid crystal molecules in each of the at least one liquid crystal lens layer is controlled by an electric field, to converge or diverge polarized light that is incident to a direction of each liquid crystal lens layer to form a focal point; a first liquid crystal lens layer is configured to converge or diverge polarized light in a first direction to form a first focal point; and the first lens layer or a second liquid crystal lens layer is configured to converge or diverge polarized light in a second direction to form a second focal point.
