The defocused lens of claim 1, wherein: the resin monomer of the outer layer in the two layers of resin monomers is a lens with uniform thickness, the thickness of the lens is 0.5 mm-1.2 mm, the resin monomer of the inner layer is a lens with non-uniform thickness, and the central thickness of the lens is 0.5 mm-1.2 mm.

20. A through-focus lens as claimed in claim 19, wherein: both the two layers of the resin monomers are spherical mirrors; or the resin monomer on the outer layer in the two layers of resin monomers is a plain lens, and the curvature of the plain lens is the same as the convex curvature of the resin monomer on the inner layer.
