The experimental procedures in the following examples were carried out in a conventional manner unless otherwise specified, and materials, reagents and the like used in the following examples were commercially available unless otherwise specified.

Example (b):

referring to fig. 1 to 4, a blue light prevention progressive lens includes a progressive lens body 1, a blue light prevention layer 2 is disposed on the outer side and the inner side of the progressive lens body 1, an antibacterial layer 3 is disposed on the surface of the inner side blue light prevention layer 2, a color changing layer 4 is disposed on the surface of the outer side blue light prevention layer 2, a heat resistant layer 5 is disposed on the surface of the color changing layer 4, a wear resistant layer 6 is disposed on the surface of the heat resistant layer 5, and an oil drainage layer 7 is disposed on the surfaces of the wear resistant layer 6 and the antibacterial layer 3.

When a wearer uses an electronic device such as a computer monitor, a fluorescent lamp, a mobile phone, a digital product and a display screen, the blue-light-proof layer 2 can absorb and block blue light to prevent the blue light from damaging eyes, after the wearer moves at a distance, facial sweat easily drips on the surface of the progressive lens body 1, the antibacterial layer 3 can kill bacteria in the sweat or make the bacteria lose activity, when the wearer is irradiated by strong light outdoors, the color-changing layer 4 darkens under the strong light, the color-changing layer 4 turns back to be transparent after the indoor light is weakened, the color-changing layer 4 can automatically adjust the color according to the strength of the light and the ultraviolet light, ultraviolet rays are automatically blocked, when the wearer wears the progressive lens body 1 in a hot weather, the heat-resistant layer 5 can block heat, the eye from generating scorching sensation due to overhigh temperature of the progressive lens body 1, when the progressive lens body 1 is cut and rubbed by foreign matters, the wear-resistant layer 6 can effectively protect the progressive lens body 1, the color-changing layer 4 and the heat-resistant layer 5, when fingers of the wearer contact with the progressive lens body 1, the grease on the progressive lens body 1 can not be scraped and the progressive lens body, and the grease-resistant progressive lens body can be easily removed, and the progressive lens device is not easily removed, and the progressive lens body is practical.

In other embodiments, the anti-bluing layer 2 is provided on both the outer and inner surfaces of the progressive lens body 1 by means of bonding; the antibacterial layer 3 is arranged on the surface of the inner blue-light-proof layer 2 in a coating mode; the color changing layer 4 is arranged on the surface of the outer blue light prevention layer 2 in an adhesion mode; the heat-resistant layer 5 is arranged on the surface of the color-changing layer 4 in an adhesion mode; the wear-resistant layer 6 is arranged on the surface of the heat-resistant layer 5 in a bonding mode; the oil-repellent layer 7 is respectively arranged on the surfaces of the antibacterial layer 3 and the wear-resistant layer 6 in a coating way

Through this design, make and prevent blue light layer 2, antibiotic layer 3, discoloration layer 4, heat-resistant layer 5, wearing layer 6 and oleophobic layer 7 and can more firmly set up on progressive lens body 1 surface to reach and avoid preventing that blue light layer 2, antibiotic layer 3, discoloration layer 4, heat-resistant layer 5, wearing layer 6 and oleophobic layer 7 drop from progressive lens body 1, prolong progressive lens body 1's life's purpose.

The blue-light-proof layer 2 is made of blue-light-proof master batches;

the blue-light-proof master batch is a plastic master batch formed by adding a composite blue-light absorbent into a common plastic base material through wet granulation, and is processed into a blue-light-proof film through processes such as injection molding, blow molding or biaxial stretching, and the like, so that the blue-light-proof master batch has the advantages of no fading, durability and simple process, and is suitable for being used as a raw material of the blue-light-proof layer 2;

the antibacterial layers 3 are all made of silver ion antibacterial films;

the silver ion disinfection antibacterial film is a film with the surface containing silver ions, and the silver ions can well destroy protein structures of bacteria and viruses and are combined with sulfur atoms in proteins to cause the loss of the activity of the proteins, so the silver ion disinfection antibacterial film is suitable for being used as a raw material of the antibacterial layer 3;

the color-changing layers 4 are made of silver halide photosensitive materials;

since the silver halide photosensitive material is a photosensitive material made of silver halide as a photosensitive substance, since the sensitivity of the silver halide photosensitive material is much higher than that of a non-silver photosensitive material and the self color thereof can be more easily adjusted according to the change of light, the silver halide photosensitive material is suitable for use as a raw material of the antibacterial layer 3;

the heat-resistant layers 5 are made of heat-insulating glass;

the heat insulating glass is a performance glass having an insignificant effect of absorbing visible light and absorbing a large amount of near infrared light generating heat, and is substantially colorless, so that it is suitable for use as a raw material of the heat-resistant layer 5;

the wear-resistant layers 6 are all made of silicon dioxide films;

the silica film is an electrolyte film with an amorphous glassy structure, is a short-range ordered network structure, is an excellent surface protection film, and can effectively improve the wear-resisting property of glass, so the silica film is suitable for being used as a raw material of the wear-resisting layer 6;

the oil-removing layer 7 is made of nano silicon dioxide;

because the composite coating material that nanometer silica made possesses good light transmissivity and hydrophobic oleophobic, makes progressive lens body 1 surface be difficult to leave the fingerprint, and it is more convenient to clean, improves progressive lens body 1's cleanliness, increases progressive lens body 1's pleasing to the eye degree, therefore nanometer silica is fit for using as the raw and other materials of oil-phobic layer 7.
