The oleophilic group of the molecule is implanted inside the lens, and the hydrophilic groups are aligned on the air side. The lipophilic group maintains a certain compatibility between the antistatic agent and the lens, and the latter adsorbs water molecules in the air to form a uniformly distributed conductive solution on the surface of the material, or self-ionizes the conductive surface charge to achieve an antistatic effect. Among them, the antistatic agent molecule may be cationic, amphoteric, anionic or nonionic.

Third embodiment

That is, the dimension of the microstructure is smaller than the wavelength of the light. When the surface structure of the material is smaller than the wavelength of the light, the refraction of the light wave will exhibit a continuous change on the surface of the material (also known as a graded index). This continuous change will occur. Causes less reflection, so it can absorb light from all sides.

Moreover, since the surface of the anti-reflection film layer 201 has a microstructure and has super-hydrophobic properties, when the anti-reflection film layer is formed on the surface of the lens body 10, the spectacle lens can be self-cleaning.

The gel, the gel network is filled with a solvent that loses fluidity, forms a gel, and the gel is dried and sintered to form the microstructure. The arrangement of the nanoparticles can be controlled by controlling the parameters at the time of dip coating or spin coating, and the shape of the microstructure is determined by the arrangement of the nanoparticles.

In other embodiments, a color film layer, a hard film layer, an anti-reflection film layer, an anti-fog film layer, and an anti-fingerprint film layer may be sequentially formed on one or two opposite surfaces of the spectacle lens 100.
