Amalensi e-HMC Optical e-1.59 PC Bifocal Invisible Photochromic Gray Optical
Njengamanje, kunezinhlobo ezimbili zezinto zelensi emakethe, enye ingilazi, enye i-resin. Izinto ze-resin zihlukaniswe zibe yi-CR-39 kanye ne-polycarbonate (izinto ze-PC).
Amalensi e-Bifocal noma amalensi e-Bifocal angamalensi aqukethe izindawo ezimbili zokulungisa ngesikhathi esisodwa futhi asetshenziswa kakhulu ukulungisa i-presbyopia. Indawo ekude elungiswa yilensi ye-bifocal ibizwa ngokuthi indawo ekude, kanti indawo eseduze ibizwa ngokuthi indawo eseduze nendawo yokufunda. Ngokuvamile, indawo ekude inkulu, ngakho-ke ibizwa nangokuthi ifilimu eyinhloko, kanti indawo eseduze incane, ngakho-ke ibizwa ngokuthi ifilimu encane.

Amalensi Optical angu-1.56 anombala ompunga ophelele
Ilensi yengilazi yelensi eshintsha umbala iqukethe inani elithile le-silver chloride, i-sensitizer kanye nethusi. Ngaphansi kwesimo sokukhanya kwamaza amafushane, ingahlukaniswa ibe ama-athomu esiliva nama-athomu e-chlorine. Ama-athomu e-chlorine awanambala kanti ama-athomu esiliva anombala. Ukuhlushwa kwama-athomu esiliva kungakha isimo se-colloidal, okuyilokho esikubona njengokushintsha kombala kwelensi. Lapho ukukhanya kwelanga kunamandla, ama-athomu esiliva ahlukaniswa kakhulu, ilensi izoba mnyama kakhulu. Lapho ukukhanya kwelanga kubuthakathaka, ama-athomu esiliva ambalwa ahlukaniswa, ilensi izoba mhlophe kakhulu. Akukho ukukhanya kwelanga okuqondile ekamelweni, ngakho amalensi aba angenambala.

Amalensi e-Optical ampunga anesithombe esifinyeziwe esingu-1.56
Inkomba yokukhanya kwelensi iphakeme, amalensi amancane, ubukhulu bokukhanya, ubulukhuni buyanda, futhi bungcono, ngokuphambene nalokho, inkomba yokukhanya iphansi, ilensi ikhulu, ubukhulu buncane, ubulukhuni buphansi, ingilazi evamile yobunzima obuphezulu, ngakho-ke inkomba yokukhanya ngokuvamile icishe ibe ngu-1.7, kanti ubulukhuni befilimu ye-resin buphansi, inkomba yokukhanya iphansi, ingxenye ye-resin emakethe njengamanje iyinkomba yokukhanya evame kakhulu engu-1.499 noma ngaphezulu, inguqulo encane kakhulu, enenkomba yokukhanya ecishe ibe ngu-1.56 futhi nayo isetshenziswa kakhulu.

Amalensi okukhanya angu-1.56 anombala oluhlaza okwesibhakabhaka oqoshiwe othambile
Izibuko eziningi zineziteshi ezimfushane neziteshi ezinde. Ukukhetha isiteshi kubalulekile. Ngokuvamile, siqala ngokucabangela ukukhetha isiteshi esifushane, ngoba isiteshi esifushane sizoba nensimu enkulu yokubuka, okuhambisana nendlela yokuphila yabantu abavame ukubheka omakhalekhukhwini babo. Umehluko phakathi kwamehlo mkhulu kakhulu, amehlo abantu abakwazi ukujikeleza kahle, nawo afanele iziteshi ezimfushane. Uma umthengi egqoke i-multi-focus okokuqala, enesidingo sebanga eliphakathi, kanti i-Add iphakeme kakhulu, khona-ke isiteshi eside singacatshangelwa.

Amalensi okukhanya ampunga anombala oluhlaza okwesibhakabhaka angu-1.56 aqediwe kancane
Ngaphansi kokukhanya kwelanga, umbala welensi uba mnyama futhi ukuhanjiswa kokukhanya kuyancipha uma kukhanyiswa yi-ultraviolet kanye nokukhanya okubonakalayo kwamaza amafushane. Kulensi yangaphakathi noma emnyama ukuhanjiswa kokukhanya kuyanda, kufiphale kubuyele ekukhanyeni. I-photochromism yamalensi iyazenzakalela futhi iyaguqulwa. Izibuko ezishintsha umbala zingalungisa ukudluliselwa ngokushintsha kombala welensi, ukuze iso lomuntu likwazi ukuzivumelanisa nezinguquko zokukhanya kwemvelo, linciphise ukukhathala kokubona, futhi livikele amehlo.

Amalensi okukhanya ampunga e-Bifocal Photo angu-1.56 aqediwe kancane
Ngokuvamile, izibuko ze-myopia ezishintsha umbala azigcini nje ngokuletha ubulula nobuhle kodwa futhi zingamelana ngempumelelo ne-ultraviolet kanye nokukhanya, zingavikela amehlo, isizathu sokushintsha kombala ukuthi lapho ilensi yenziwe, ixutshwa nezinto ezizwela ukukhanya, njenge-silver chloride, i-silver halide (eyaziwa ngokuthi i-silver halide), kanye nenani elincane le-copper oxide catalyst. Noma nini lapho i-silver halide ikhanyiswa ukukhanya okunamandla, ukukhanya kuzobola futhi kube yizinhlayiya eziningi zesiliva ezimnyama ezisatshalaliswa ngokulinganayo kulensi. Ngakho-ke, ilensi izobonakala ifiphele futhi ivimbele ukudlula kokukhanya. Ngalesi sikhathi, ilensi izoba nombala, okungavimbela kahle ukukhanya ukufeza injongo yokuvikela amehlo.

Amalensi e-Optical anombala ompunga anombala oluhlaza okwesibhakabhaka angu-1.56 aqediwe kancane
Amalensi ashintsha umbala aba mnyama uma ilanga likhanya. Uma ukukhanya kunyamalala, kuphinde kukhanye. Lokhu kungenzeka ngoba amakristalu e-silver halide ayasebenza.
Ngaphansi kwezimo ezijwayelekile, igcina amalensi ekhanya ngokuphelele. Uma evezwa elangeni, isiliva elisekristalini liyahlukaniswa, bese isiliva elikhululekile lakha ama-aggregate amancane ngaphakathi kwelensi. Lawa ma-aggregate amancane esiliva ayizinhlayiya ezingavamile, ezixhumene ezingakwazi ukudlulisa ukukhanya kodwa zimunce, okwenza ilensi ibe mnyama ngenxa yalokho. Uma ukukhanya kuphansi, ikristali iyashintsha futhi ilensi ibuyele esimweni sayo sokukhanya.

Amalensi e-HMC Optical angu-1.56 aluhlaza okwesibhakabhaka aqoshiwe i-Progressive Photochromic Gray
Izibuko ezithuthukisiwe ze-multifocal zasungulwa eminyakeni engama-61 eyedlule. Izibuko eziningi ezigxile ku-multifocal zaxazulula inkinga yokuthi abantu abaseminyakeni ephakathi nabadala badinga ukukhanya okuhlukile ukuze babone izinto ezikude ezahlukene futhi badinga ukushintsha izibuko njalo. Izibuko ezimbili zingabona kude, zinhle, futhi zingabona eduze. Ukufaniswa kwezibuko eziningi ezigxile ku-multifocal kuyiphrojekthi ehlelekile, edinga ubuchwepheshe obuningi kakhulu kunokufaniswa kwezibuko ze-monocal. Odokotela bamehlo abadingi nje ukuqonda i-optometry, kodwa futhi badinga ukuqonda imikhiqizo, ukucubungula, ukulungiswa kohlaka lwesibuko, ukulinganiswa kokugoba kobuso, i-Angle phambili, ibanga lamehlo, ibanga lomfundi, ukuphakama komfundi, ukubalwa kokushintsha kwesikhungo, isevisi yangemva kokuthengisa, ukuqonda okujulile kwezimiso zokugxila okuningi, izinzuzo kanye nokungalungi, njalo njalo. Uchwepheshe ophelele kuphela ongacabangela amakhasimende ngokuphelele, ukuze afane nezibuko ezifanele ze-multi-focal.
