Imiba yomgangatho wangaphakathi weelensi zeresin:
1. Isiseko sezinto eziphathekayo
Umgangatho we-substrate unquma ukuqina kwelensi kunye nokuthembeka kwengubo.I-substrate elungileyo ecacileyo kwaye eqaqambileyo, ixesha elide lokusebenzisa kwaye akukho lula ukutyheli;Kwaye ezinye iilensi zisebenzisa ixesha alide lijike libe tyheli, nokuba liyagquma.I-lens elungileyo ngaphandle komkrwelo, umkrwelo, iinwele, i-pitting, i-lens oblique ekubonweni kokukhanya, ukugqiba okuphezulu.Akukho mabala, amatye, imivimbo, amaqamza kunye nokuqhekeka ngaphakathi kwelensi, kwaye ukukhanya kuqaqambile.
2. Ibakala lelensi
Iilensi eziveliswe ngobuninzi zohlulwe ngokwamabakala ahlukeneyo ngenxa yomahluko kumgangatho wangaphakathi, kwaye amaxabiso eemveliso eziphezulu nezingaphantsi ahluka kakhulu.
3. Isalathiso se-refraction
I-index ye-refractive ephezulu, i-lens encinci, kunye nexabiso eliphezulu.
4. Ukwambathisa kunye ne-anti-ultraviolet unyango
Iphepha le-resin linokuba lukhuni (ukuchasana nokukrala), ukuchasana-reflection, i-anti-static, i-dustproof, ukusetyenzwa kwamanzi okugquma amanzi amaninzi amaninzi njengeshumi elinesibini, ukusetyenzwa kweengubo ezahlukeneyo kunendima eyahlukileyo, ukuba ukunciphisa inkqubo yokugubungela, umgangatho we-lens. ziya kuncitshiswa kakhulu.Ngokufanayo, kuyingozi kakhulu emehlweni ukuba iilensi ezingathinteli imitha ye-ultraviolet zinxitywe njengeelensi ezikhusela imitha ye-ultraviolet.Iliso lomntu lithatha ukukhanya okukhulu kwe-ultraviolet ukuze kubangele lula izifo zamehlo ezifana ne-photoinduced keratitis, i-cataract kunye ne-macular degeneration.
5. Uphawu lwelensi
Ukwahluka kwebrendi kukhokelela kumahluko kumgangatho kunye nexabiso.Umgangatho welensi ubonakaliswa ngokuthe ngqo kwi-brand lens.Umgangatho welensi edumileyo ulungile kwaye uzinzile.Njengoko i-lens icutshungulwa ngasemva, nokuba iyinyani okanye ayikho, abathengi abanako ukulandelela kunye nokuchonga, ngokukodwa bathembele kwingqibelelo yomsebenzisi.Indlela yokholo oluhle kukuba xa abathengi befanisa iiglasi, umnini-venkile kufuneka abonise uphawu, iindidi, isalathiso se-refractive kunye nemeko yokugubungela i-lens kuxwebhu, kunye nokukwazi ukukhusela ukukhanya kwe-ultraviolet kufuneka kuchazwe kumthengi.Ukuba i-resin lens ibhaliwe ngokubanzi, ukungafani kukhulu kakhulu, umgangatho wangaphakathi we-lens ayaziwa.Ibakala le-ABC lisetyenziselwa ukwahlula xa umenzi evelisa, enyanisweni, umgangatho wesizwe awufuni lo mahluko.Ewe kunjalo, akukhathaliseki nokuba leliphi ibakala le-ABC lens elifanelekileyo.
6. Ukungafihli kunye nokufana kwe-optical ye-lens
Bamba ilensi 30 cm kude neliso kwaye ujonge imbonakalo ekude ngelensi.Ukuba imbonakalo yelizwe icacile kwaye ingenakuguqulwa, kwaye akukho ndawo yokutsiba xa uhambisa ilensi kancinane, ukungafihli kunye nokufana kokubona kwelensi kulungile.
7. Ulwalathiso lwe-axial ye-astigmatism lens
Kwiphepha elingenanto ukuzoba umnqamlezo ifolokhwe perpendicular, beka ilens kwi spider jikelisa umzobo ngaphezu 30 centimeters, lens ebonakalayo ukuhambisa umnqamlezo ifolokhwe umnqamlezo, ilens ngaphakathi kwaye xa uqhagamshelwe imizobo umnqamlezo, imizobo wayeqinisekile cross, apho ikholamu i-axis yelensi kunye nomgca othe ngqo, emva koko iilensi zazihamba ngokuphindaphindiweyo kumgca othe ngqo;Qaphela ukuba ngowuphi umgca owahluka kakhulu kumgca ongaphandle kwelensi xa ushukuma, kwaye lo mgca licala le-axis ye-scatterlight.Hambisa i-lens ukuze umgca wangaphakathi nangaphandle unyuke, nantsi i-axis yokwahlukana.Emva kokumakisha kwi-lens, linganisa i-Angle ye-axial kunye ne-horizontal embindini we-lens kunye ne-protractor, eyi-axial degree.
8. Ukufuduswa kweziko le-Optical
Zoba umnqamlezo omkhulu kwisiqwenga sephepha elimhlophe kumgca omncinci, ocacileyo, othe ngqo.Bamba i-lens phakathi kwamehlo kunye nomnqamlezo, jonga ubume bomnqamlezo kwisibuko ngeliso elinye, ukuba ngaphakathi nangaphandle kwesibuko asikho kumgca, unokuhambisa i-lens, ukwenzela ukuba ngaphakathi kwe-lens umphandle wesipili umgca wokunqumla.Sebenzisa ibrashi okanye ipeni lomthombo ukuze ubeke inqaku elincinci kwiziko le-lens, eliziko le-optical.Emva kokukhomba amaziko okukhanya kuzo zombini iilensi, jonga kwaye uqhathanise ukuba ngaba amaziko optical amabini ane-symmetrical, kwaye ulinganise umgama phakathi kwamaziko amabini kunye nomlawuli omncinci ukubona ukuba umgama phakathi kwamaziko amabini uhambelana nomgama omiselweyo kumfundi. .Ukuba umnqamlezo kwi-lens ugobile, kubonisa ukuba kukho uxinzelelo lwangaphakathi okanye ukuxinana kwe-optical engalinganiyo ye-lens.
9. Nxiba intuthuzelo
Nxiba ngaphandle kokuziva, isiyezi kunye nokudumba kwamehlo, izinto zokujonga azikho mfiliba, azikhubeki.Xa uthenga, bamba iindondo ngesandla kwaye ujonge izinto ezikude ngeliso elinye kwilensi.Gcoba i-lens phezulu naphantsi.Inkohliso yokuhamba kwezinto ezikude akufanele yenzeke.
10. Ukhuseleko
Iilensi ezikumgangatho ophezulu zinokuvimba nge-100% i-UV A kunye ne-UV B, zibonelela ngokhuseleko olusebenzayo kwi-uv kumntu onxibileyo.
