Emkhakheni we-optical innovation, idizayini yelensi ihlukaniswa ngokuyinhloko ngezinhlobo ezimbili: eyindilinga ne-aspheric. Amalensi ase-aspheric, aqhutshwa ukuphishekela ukuba nomzimba omncane, adinga uguquko ekugoqeni kwelensi, ahluke kakhulu ekujikeni kwendawo eyindilinga yelensi. Umklamo oyindilinga, owawuvamile ngaphambili, wawukhungethwe ukuchezuka nokuhlanekezela okwengeziwe. Lokhu kuvame ukuholela ezinkingeni ezishiwoyo njengezithombe ezifiphele, ukubona okusontekile, kanye nenkambu yokubuka elinganiselwe.
Manje, umklamo we-aspheric uvele njengamandla okulungisa, ukubhekana nalokhu kuhlanekezela okubukwayo ngokuphumelelayo futhi unikeze isisombululo esinikeza amalensi angagcini nje ngokukhanya futhi amancane kodwa futhi afane flat. Okubalulekile, lokhu kuthuthukiswa akuphazamisi ukumelana nokushayisana okuvelele kwamalensi, kuqinisekisa ukuzizwisa okuphephile kokugqoka.
Amalensi ayisiyingi endabuko anecala eliphansi eliphawulekayo - izinto ezibukwa emaphethelweni e-lens zibonakala zihlanekezelwe, zicindezela umkhakha wokubuka walowo ogqokile. Esikhathini lapho ubuchwepheshe buguquka ngokuqhubekayo, ama-aspheric lens - isimangaliso sangempela sokubona - anciphisa ukuphambana emaphethelweni amalensi, anweba kakhulu umkhakha wokubuka ukuze ahlangabezane nezidingo zamakhasimende. Amalensi e-aspheric afaka ijika eliyisicaba futhi alula, athuthukisa ukukhanga kwemvelo nobuhle. Ikakhulukazi ezimeni zamandla aphezulu okubonisa, anciphisa kahle ukuhlanekezela kwamehlo, awenze abe yinketho ekahle kubathengi abanezidingo eziphezulu zemiyalelo kadokotela.
Isici esichazayo samalensi ase-aspheric ukugoba kwawo okuyingqayizivele kwendawo. Lo mklamo we-aspheric unikeza izinzuzo ezimbalwa ngaphezu kwamalensi ayindilinga endabuko:
I-1.Ukucaca: Ukuphathwa ngenqubo yokuhlanganisa okukhethekile, amalensi ase-aspheric ahlinzeka ngokusebenza okubonakalayo okuyisibonelo, okuqinisekisa ukuzizwisa okucacile nokunethezekile kokubuka.
2.Comfort: Ngakho-ke alula acishe angabonakali, amalensi ase-aspheric anciphisa 'isisindo' emehlweni akho, avumele ukugqokwa okukhululekile nokulula.
3.Umbono Wemvelo: Idizayini yazo eyi-aspheric inciphisa ukuhlanekezela okubonakalayo, okuholela ekuboneni okungokoqobo nokunembe kakhudlwana.
Uma kuqhathaniswa amalensi ayindilinga nawe-aspheric wento efanayo kanye nencwadi kadokotela, amalensi ase-aspheric agqama njengokucaba, mancane, futhi anikeze ukuzizwisa okungokoqobo nokunethezekile kokubuka. Ukubuka ukuma kwelensi enamathelayo ngokumelene nomthombo wokukhanya kuveza ukuthi ukuboniswa okuvela kumalensi ayindilinga ngokuvamile kuqondile (ngaphandle kwamalensi amandla acwebezelayo); amalensi aspheric, nokho, abonisa ukugoba okukhulu ngenxa yokugoba okuhlukahlukayo endaweni yawo.
Amaphethelo azungezayo amalensi ayindilinga endabuko awabonakali nje kuphela ajiyile kodwa futhi ahlanekezela futhi asonte umbono wezinto, into eyaziwa ngokuthi ukuphambana kwesithombe. Ukuze kuzuzwe idizayini engasindi, kusetshenziswe izinto zenkomba ye-refractive ephezulu ekukhiqizeni amalensi. Ngaphezu kwalokho, lapho ebhekwa ngamalensi ayindilinga, ukubukeka kobuso bomuntu ogqokile kuhlanekezelwe ngokuphawulekayo. Amalensi e-aspheric, ngokuphambene, anciphisa kokubili ukujiya okumaphakathi nonqenqema, okuholela kumalensi azacile asusa ukuphambuka kwe-peripheral, ngaleyo ndlela anikeze umuzwa obonakalayo wemvelo.
Amalensi ase-aspheric anikeza inkambu yokubuka ebanzi nengagobile emaphethelweni, nokuhlanekezela okuncane kwesithombe, okwenza izithombe zibe ngokwemvelo ngendlela emangalisayo. Lawa ma-lens anzima ngokuphindwe kathathu kunawabo ayindilinga, okuwenza afaneleke kakhulu kubagibeli abasha. Ngencwadi kadokotela efanayo -5.00DS, amalensi aspheric alula ngo-26% kunamalensi ayindilinga. Indawo yazo eyisicaba iqinisekisa umbono wemvelo, ongasontekile womhlaba, eduze nakude, okunciphisa ukukhathala kwamehlo isikhathi eside.
Ilungele abagqoki bezibuko zamehlo okokuqala ngqa, ikakhulukazi abafundi nabasebenzi basehhovisi, amalensi e-aspheric akudambisa ngokuphawulekayo ukungakhululeki kwasekuqaleni okuhlobene nokugqoka izibuko. Futhi ziyindlela enhle kakhulu yabasebenzisi belensi yokuxhumana, esebenza njengezingubo zamehlo eziyisipele ekhaya. Amalensi ase-aspheric alingisa eduze ukubona kwemvelo, ngokufana nolwazi lwamalensi okuxhumana. Aphelele kulabo abancamela ukubukela phansi imiyalelo yabo ephezulu, abafisa ukugwema ukubukeka kwamehlo amancane ngezibuko ze-myopia, bafune ukwenza lula isisindo samalensi abo, noma babe nezidingo ezihlukile zokugqamisa iso ngalinye.
Amalensi ase-aspheric anganikeza amalensi enkomba aphakathi nendawo abukeka ngendlela efanayo ezacile futhi eyisicaba njengamalensi enkomba ecwebezelayo, anciphise ukuphambuka onqenqemeni futhi ahlinzekele indawo ebanzi yokubuka eyanelisa zonke izidingo zamakhasimende.
