The present disclosure relates to a preparation method for a photochromic lens with a bifocal film layer. A photochromic lens with a bifocal film layer includes a substrate, a treatment layer, and a photochromic layer from inside to outside, where the photochromic layer is cured on a surface of the treatment layer by means of ultraviolet irradiation. According to the preparation method for a photochromic lens having a bifocal film layer provided in the present disclosure, a bifocal lens is used as a lens substrate, and photochromic and bifocal technologies are combined to overcome the defect of non-uniformity of a bifocal film layer caused by a spin-coating method, such that a photochromic layer can be uniformly attached to a surface of the lens substrate. Thus, uniform photochromism and excellent performance are achieved, and it can be ensured that the surface shape luminosity of the bifocal lens substrate is not affected.

A photochromic ophthalmic lens includes a body and photochromic molecule-cyclodextrin inclusion compounds dispersed in the body. The photochromic molecule-cyclodextrin inclusion compounds include cyclodextrins and photochromic molecules entrapped in a cavity of the cyclodextrins. Notwithstanding the hydrophobic nature of the photochromic molecules, the cyclodextrins, which contains cavities entrapping the photochromic molecules, are hydrophilic.
