Description
Technical Field
The utility model relates to the technical field of spectacle lenses, in particular to a blue light resistant spectacle lens.
Background
With the improvement of living standard of people and the continuous progress of mobile internet technology, electronic devices such as televisions, mobile phones and computers are deeply inserted into the lives of people, screens of the electronic devices have strong electromagnetic radiation which can damage human eyes, and meanwhile, a large amount of high-energy short-wave blue light with irregular frequency can be brought, and the blue light irradiation can enable retinas to generate free radicals, so that retinal pigment epithelial cells die, and finally the eyesight of people is reduced.
However, the existing blue-light resistant spectacle lens has poor impact resistance and toughness, so that the lens is easy to break when being subjected to external impact force, so that the fragments of the lens easily stab the eyes of a user, and the safety is low; in the wearing process, a user can inevitably splash water stains or oil stains on the lens, but the existing lens needs to be cleaned by the aid of the cleaning agent to enable the lens to be recovered to be clean, the cleaning agent needs to be carried with the user, and the lens is inconvenient to clean and inconvenient to use.
SUMMERY OF THE UTILITY MODEL
The present invention is directed to solving the above problems and providing an anti-blue light spectacle lens.
The utility model achieves the above object by the following technical scheme, and the blue light resistant spectacle lens comprises a structure main body, a lens and a lens holder, wherein the structure main body comprises a transparent substrate;
the upper surface of the transparent substrate is sequentially provided with an upper hardness enhancement layer, a blue light resistant layer, an antifogging layer and an upper scratch resistant layer;
and the lower surface of the transparent substrate is sequentially provided with a lower hardness enhancement layer, an oil stain prevention layer and a lower scratch prevention layer.
Preferably, the upper hardness enhancement layer and the lower hardness enhancement layer are hard films.
Preferably, the transparent substrate is a transparent resin substrate.
Preferably, the material of the oil stain prevention layer is a nano coating.
Preferably, the upper and lower hardness-enhancing layers have a thickness ranging from 2 μm to 5 μm.
Preferably, the thickness of the blue light-resistant layer ranges from 3 μm to 7 μm.
Preferably, the transparent substrate has a center thickness in the range of 1.3mm to 2.0 mm.
The utility model has the beneficial effects that:
according to the blue-light-resistant spectacle lens, the upper hardness enhancement layer and the lower hardness enhancement layer are respectively arranged on the two sides of the transparent substrate, so that the hardness of the spectacle lens is enhanced, and the shock resistance of the spectacle lens is improved; through the setting on grease proofing dirty layer, antifog layer and anti-scratch layer for the lens not only has the better anti blue light effect of anti blue light, has better grease proofing dirty performance, better antifog performance and better anti-scratch performance simultaneously.

FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a cross-sectional view of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1-2:
the blue light resisting spectacle lens in the embodiment comprises a structural main body, wherein the structural main body comprises a transparent substrate 1; the upper surface of the transparent substrate 1 is sequentially provided with an upper hardness enhancement layer 4, a blue light resistant layer 5, an antifogging layer 6 and an upper scratch-resistant layer 7; the lower surface of the transparent substrate 1 is sequentially provided with a lower hardness enhancement layer 2, an oil stain prevention layer 3 and a lower scratch prevention layer 8.
Wherein, the upper hardness enhancement layer 4 and the lower hardness enhancement layer 2 are stiffened films; the transparent substrate 1 is a transparent resin substrate; the material of the oil stain prevention layer 3 is a nano coating; the thickness ranges of the upper hardness enhancement layer 4 and the lower hardness enhancement layer 2 are 2-5 μm; the thickness range of the blue light resistant layer 5 is 3-7 μm; the central thickness of the transparent substrate 1 ranges from 1.3mm to 2.0 mm.
According to the blue-light-resistant spectacle lens, the upper hardness enhancement layer and the lower hardness enhancement layer are respectively arranged on the two sides of the transparent substrate, so that the hardness of the spectacle lens is enhanced, and the shock resistance of the spectacle lens is improved; through the setting on grease proofing dirty layer, antifog layer and anti-scratch layer for the lens not only has the better anti blue light effect of anti blue light, has better grease proofing dirty performance, better antifog performance and better anti-scratch performance simultaneously.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
