Abstract
The utility model provides a presbyopic glasses piece, including the substrate, this substrate includes first mirror surface and the second mirror surface relative with this first mirror surface, and this first mirror surface from interior to exterior is equipped with reflection reducing coating, anti -radiation film, antireflection film, scratch -resistant film layer and water proof membrane in proper order, and this second mirror surface from interior to exterior is equipped with reflection reducing coating, anti -radiation film, antireflection film, scratch -resistant film layer and water proof membrane in proper order. Above -mentioned presbyopic glasses piece, because this presbyopic glasses piece's both sides, from interior to exterior is equipped with reflection reducing coating, anti -radiation film, antireflection film, scratch -resistant film layer and water proof membrane in proper order, the institute can lengthen this presbyopic glasses piece's life so that this presbyopic glasses piece has anti -reflection, radiation protection, antireflection, prevents scraping and waterproof function to protection user's glasses.
Description
Technical field
This utility model relates to optometric technology field, particularly to a kind of presbyopic glass block.
Background technology
After people a to dating, the crystalline lens of human eye can gradually fibrosclerosis, ciliary muscle can gradually fiber crops
Numbness, makes human eye cannot effectively regulate the shape of eyeball, can only by the distance of regulation eyes and regarded object,
Just can see regarding object, this normal physiological phenomenon is referred to as presbyopia, and the generation of reading glasses is proper
Solve well this problem, have after presbyopic people puts on reading glasses, eyes and regarded thing need not be regulated
The distance of body, it is possible to directly see clearly regarding object.
Reading glasses in the market generally comprise picture frame, temple and two pieces of presbyopic glass blocks.Existing always
Presbyopia eyeglass still suffers from some shortcomings: 1, eyeglass is the most wear-resisting, and surface is easily scratched；2, darkening weak effect,
It is only applicable under high light use, is not suitable for using at dark；3, poor filtration effect, definition is the highest.
Utility model content
Based on this, the purpose of this utility model is to provide a kind of presbyopic glass block with multiple-protection function.
A kind of presbyopic glass block, including substrate, this substrate includes the first minute surface and relative with this first minute surface
Second minute surface, this first minute surface is sequentially provided with anti-reflection film, radiation prevention film, antireflection film, scratch resistant from the inside to the outside
Film and waterproof membrane, this second minute surface is sequentially provided with anti-reflection film, radiation prevention film, antireflection film from the inside to the outside, prevents
Knifing and waterproof membrane.
Further, this substrate is aspherical lens, and this substrate is from center to periphery, and radius of curvature gradually increases
Add.
Further, the material that this anti-reflection film uses is in the middle of Afluon (Asta), titanium oxide, vulcanized lead or lead selenide
One.
Further, this preventing from scraping film uses the one in the middle of TAC film or SFM plated film.
Above-mentioned presbyopic glass block, due to the both sides of this presbyopic glass block, be sequentially provided with from the inside to the outside anti-reflection film,
Radiation prevention film, antireflection film, preventing from scraping film and waterproof membrane, so that this presbyopic glass block has anti-reflection, anti-
Radiation, antireflection, scratch resistant and water-proof function, can extend the service life of this presbyopic glass block, and protection makes
The glasses of user.
Accompanying drawing explanation
Fig. 1 is the axonometric chart of a kind of presbyopic glass block in this utility model first embodiment.
Fig. 2 is the cross sectional representation of presbyopic glass block in Fig. 1.
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
Description.Accompanying drawing gives some embodiments of the present utility model.But, this utility model can be to be permitted

The purpose of example is to make to disclosure of the present utility model more thoroughly comprehensively.
It should be noted that when element is referred to as " being fixedly arranged on " another element, and it can be directly at another yuan
On part or element placed in the middle can also be there is.When an element is considered as " connection " another element, and it can
To be directly to another element or to may be simultaneously present centering elements.Term as used herein " is hung down
Straight ", " level ", "left", "right" and similar statement for illustrative purposes only.
Unless otherwise defined, all of technology used herein and scientific terminology with belong to of the present utility model
The implication that those skilled in the art are generally understood that is identical.Institute in description of the present utility model herein
The term used is intended merely to describe the purpose of specific embodiment, it is not intended that in limiting this utility model.
Term as used herein " and/or " include the arbitrary and all of of one or more relevant Listed Items
Combination.
Refer to Fig. 1 and Fig. 2, a kind of presbyopic glass block provided in first embodiment in this utility model, bag
Including substrate 10, this substrate 10 includes the first minute surface 101 and second minute surface relative with this first minute surface 101
102, this first minute surface 101 be sequentially provided with from the inside to the outside anti-reflection film 11, radiation prevention film 12, antireflection film 13,
Preventing from scraping film 14 and waterproof membrane 15, this second minute surface 102 is sequentially provided with anti-reflection film 11, radioprotective from the inside to the outside
Film 12, antireflection film 13, preventing from scraping film 14 and waterproof membrane 15.
This substrate 10 is aspherical lens, and this substrate 10 is from center to periphery, and radius of curvature is gradually increased.
This anti-reflection film 11 can increase the transmittance of this presbyopic glass block so that user is by these reading glasses
Sheet can improve the definition of viewing things.The material that this anti-reflection film uses is Afluon (Asta), titanium oxide, sulfuration
One in the middle of lead or lead selenide.
This radiation prevention film 12 can filter out major part purple light and blue light so that through the light of this presbyopic glass block
Main based on yellow, green, HONGGUANG, so just become apparent from by this presbyopic glass block imaging.
This antireflection film 13 can effectively abandon the radiating light in the external world.
This preventing from scraping film 14 uses TAC film or SFM plated film so that this preventing from scraping film has high wear-resistant, keeps away
Exempt from user and in use this presbyopic glass block is caused abrasion, extend the use longevity of this presbyopic glass block
Life.
This waterproof membrane 15 can alleviate the atomizating phenomenon that this presbyopic glass block occurs at misty rain weather or winter.
To sum up, in this utility model above-described embodiment, due to the both sides of this presbyopic glass block, depend on from the inside to the outside
Secondary anti-reflection film 11, radiation prevention film 12, antireflection film 13, preventing from scraping film 14 and the waterproof membrane 15 of being provided with, institute so that
Obtain this presbyopic glass block and there is anti-reflection, radioprotective, antireflection, scratch resistant and water-proof function, this presbyopia can be extended
The service life of lens, and protect the glasses of user.
Embodiment described above only have expressed certain 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.
