Description
Technical field
The present invention relates to a kind of integrate the contact lenss processing technology becoming normal complexion anti-ultraviolet.
Background technology
Contact lenss (contact lens), are also corneal contact lenss, are that one kind is worn on cornea, use
With correct defects of vision or protect eyes eyeglass, contact lenss not only from appearance with convenience in terms of to myopia,
The ametropia patient such as hypermetropia, astigmatism brings very big improvement, is controlling adolescent myopia, astigmatism in addition
The aspects such as the special oculopathy of development, treatment have also played special effect.
With the continuous improvement of social economy's level, people exist to beautiful requirement also more and more higher, contact lenss
Additionally it is possible to play the effect of beautification eyes, therefore, people also can be by using stealth while protect eyes
Glasses are changing the color of oneself iris.Stealthy eye now with the changed iris color of a large amount of different colours
Mirror, but, often pair can only fix a kind of color of offer, because these contact lenss exist to existing contact lenss
It is the formation of certain fixing color when production.If wearer wants the stealthy eye using different colours
Mirror, needs old contact lenss to be taken off loaded down with trivial detailsly and change the contact lenss of his wanted color, and warp
Often changing contact lenss can be very inconvenient.
And, contain ultraviolet, blue light etc. in sunlight, computer, TV, mobile phone or workshop
Harmful light.The cornea of human eye and crystal are highly susceptible to the injury of ultraviolet, the impact to eyeball for the ultraviolet
Very big, the harm to eyes for the ultraviolet, eyes are chronically exposed under burning sun, and be first subjected to impact is black eye
Pearl, if tanned by the sun in a large number, can cause cornea injured, and the eyes of people can pain, uncomfortable, stream immediately
The symptoms such as tear；Secondly, crystalline lenss sustain damage, and eyes are irradiated by ultraviolet for a long time, can make originally to be distributed
Uniform crystalline lenss chain is interrupted, and becomes irregular, reduces transmittance, affects one's power of vision；Secondly, view
Film is also affected by ultraviolet deeply, and retina is located at the nerve of eyeball rear, just cannot recover once going to pot again,
Due to the severe contamination of modern industry, ozone layer goes to pot commonly referred to as macula degeneration, and ultraviolet only can
Increasingly stronger, using sunglassess, eyes being carried out with protection is requisite means.
It would therefore be desirable to research and develop a kind of new contact lenss.
Content of the invention
It is an object of the invention to：For above-mentioned technical problem, a kind of collection is provided to become normal complexion UV resistance

Step S4, liquid feeding, color-change powder is configured to liquid, then mixes with the stock solution prepared in step S3；
Step S5, curing molding, the liquid that step S4 is obtained injects drying forming in above-mentioned half mold
For eyeglass contact lenss blank material, this eyeglass contact lenss blank material and half mold one complex of formation；
Step S6, the eyeglass contact lenss blank material on described complex is exposed by eyeglass turning with lathe
Side turnery processing becomes the spherical shape needing；
Step S7, eyeglass polishes, and carries out surface polishing to described turning surface；
Step S8, takes piece, and eyeglass is taken out from half mold；
Step S9, hydration, the eyeglass of taking-up is carried out, extracts and fixation；
Step S10, surface go-on-go, luminosity inspection, the eyeglass being hydrated is put into circulation disk and carries out surface matter
Amount and focal power inspection；
Step S11, packaging material cleaning, preservation liquid are prepared, and packaging material are carried out, dry, and prepare
The preservation liquid of eyeglass；
Step S12, cleans subpackage, and the preservation liquid in step S11 and cleaned packaging material are used for
Packaging contact lenss；
Step S13, sterilizing, packaging, the subpackage finished product in step S12 is carried out disinfection by ultraviolet light, and
Packaged with packing box；
Step S14, finished product is put in storage, by final packaged finished product warehouse-in.
Preferably, the curvature of contact lenss in described step S1 is matched with the cambered surface of cornea eye.
Preferably, the drying temperature of the packaging material in described step S11 is 100 DEG C.
Preferably, described color-change powder enables to contact lenss for one kind and reacting with light and makes hidden
