Abstract
The utility model provides a presbyopic lens, includes optical lens lamella and polarizing film layer, the optical lens lamella with the polarizing film layer further includes the stiffened rete through viscose layer bonding, the polarizing film level in the stiffened rete with between the optical lens lamella, the stiffened rete with still be equipped with an antireflection film layer between the polarizing film layer. The utility model provides a presbyopic lens through setting up polarizing film layer, stiffened rete and antireflection film layer, can make this presbyopic lens have stronger fastness to wear, has polarisation and antireflection function simultaneously, and it is more clear that the messenger person of wearing in old age looks the thing.
Description
Technical field
This utility model relates to optometric technology field, particularly relates to a kind of presbyopic lens.
Background technology
Presbyopia, is commonly called as presbyopia, is owing to eye regulation power declines, it is impossible to see specific close-in target at the moment clearly,
Cannot be carried out reading or a kind of physiological phenomenon of near work, be must to occur after people step into person in middle and old age
Visual problem, need to use the rectification of presbyopia correcting lens, i.e. reading glasses to carry out reading or other closely
Work.The reading glasses of prior art, its presbyopic lens after long-term use, can be because of wiping or other reason
Causing eyeglass to wear and tear, the old wearer of impact regards the definition of thing.
Utility model content
In view of above-mentioned condition, it is necessary to provide a kind of presbyopic lens, solve presbyopic lens in prior art and easily grind
Damage, the problem that blurring of vision is clear.
A kind of presbyopic lens, including optical frames lamella and light polarizing film layer, described optical frames lamella and described polarisation
Film layer is bonded by an adhesive-layer, it is characterised in that farther include to add hard membrane layer, described light polarizing film layer position
Add between hard membrane layer and described optical frames lamella in described, described in add between hard membrane layer and described light polarizing film layer also
It is provided with an antireflection film layer.
Above-mentioned presbyopic lens, wherein, described in add hard membrane layer use diamond-film-like.
Above-mentioned presbyopic lens, wherein, the thickness of described antireflective coating is less than or equal to 5um.
Above-mentioned presbyopic lens, wherein, described adhesive-layer uses OCA optical cement.
Above-mentioned presbyopic lens, wherein, the thickness of described OCA optical cement is less than or equal to 75um.
Above-mentioned presbyopic lens, wherein, described optical frames lamella uses resin presbyopic lens.
The presbyopic lens that the utility model proposes, by arranging light polarizing film layer, adding hard membrane layer and antireflection film layer,
This presbyopic lens can be made to have stronger abrasion-resistance, there is polarisation and anti-reflection function simultaneously, make old age
Wearer becomes apparent from depending on thing.
Accompanying drawing explanation
Fig. 1 is the structural representation of the presbyopic lens that this utility model one embodiment proposes.
Detailed description of the invention
For the ease of understanding this utility model, below with reference to relevant drawings, this utility model is carried out more comprehensively

Term as used herein " and/or " include the arbitrary and all of of one or more relevant Listed Items
Combination.
Referring to Fig. 1, the presbyopic lens 10 that this utility model one embodiment proposes, it includes optical frames lamella
110 and light polarizing film layer 120.
In the present embodiment, described optical frames lamella 110 uses resin presbyopic lens, described light polarizing film layer 120
Including the polyethylene film as basement membrane and the PET film as protecting film.
Described optical frames lamella 110 is bonded by an adhesive-layer 130 with described light polarizing film layer 120, described viscous
Glue-line 130 uses OCA optical cement, and the thickness of described OCA optical cement is less than or equal to 75um, specifically at this
In embodiment, the thickness of described OCA optical cement is 75um
Described presbyopic lens 10 farther includes to add hard membrane layer 140, described in add hard membrane layer 140 be positioned at described partially
The outer layer of light film layer 120, the most described light polarizing film layer 120 be positioned at described in add hard membrane layer 140 and described optical frames
Between lamella 110, described in add hard membrane layer 140 and use diamond-film-like, there is stronger abrasion-resistance.
Described adding, is additionally provided with an antireflection film layer 150 between hard membrane layer 140 and described light polarizing film layer 120, described
The thickness of antireflection film layer 150 is less than or equal to 5um.
The presbyopic lens that the utility model proposes, by arranging light polarizing film layer, adding hard membrane layer and antireflection film layer,
This presbyopic lens can be made to have stronger abrasion-resistance, there is polarisation and anti-reflection function simultaneously, make old age
Wearer becomes apparent from depending on thing.
Embodiment described above only have expressed a kind of embodiment of the present utility model, its describe more concrete and
In detail, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that,
For the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to
Making some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, this utility model
The protection domain of patent should be as the criterion with claims.
