Ukuhlukaniswa kwezinto ezintathu ezinkulu
Amalensi engilazi
Ezinsukwini zokuqala, izinto eziyinhloko zamalensi kwakuyingilazi ye-optical.Lokhu kwakungenxa yokuthi amalensi engilazi abonakalayo anokudlulisa ukukhanya okuphezulu, ukucaca okuhle, kanye nezinqubo zokukhiqiza ezivuthiwe nezilula.Nokho, inkinga enkulu ngamalensi engilazi ukuphepha kwawo.Azikwazi ukumelana nomthelela omubi futhi kulula kakhulu ukuzigqashula.Ukwengeza, zinzima futhi azikhululekile ukugqoka, ngakho-ke isicelo sazo semakethe samanje silinganiselwe.
Ama-resin lens
Amalensi e-resin amalensi abonakalayo enziwe ngenhlaka njengempahla eluhlaza, acutshungulwa futhi ahlanganiswe ngezinqubo zamakhemikhali ezinembile kanye nokupholishwa.Njengamanje, izinto ezisetshenziswa kakhulu zamalensi yi-resin.Amalensi e-resin anesisindo esilula uma kuqhathaniswa namalensi engilazi ebonakalayo futhi anokumelana nomthelela onamandla kunamalensi engilazi, okuwenza mancane amathuba okuthi aphuke futhi ngaleyo ndlela kuphephe ukuwasebenzisa.Ngokwentengo, amalensi e-resin nawo athengeka kakhulu.Kodwa-ke, amalensi e-resin awakwazi ukumelana nokuklwebheka, akhipha i-oxidize ngokushesha, futhi athambekele kakhulu ekuklwebheni phezulu.
Amalensi e-PC
Amalensi e-PC amalensi enziwe nge-polycarbonate (i-thermoplastic material) akhiwa ngokufudumeza.Lokhu okubalulekile kwavela ocwaningweni lohlelo lwasemkhathini futhi kwaziwa nangokuthi amalensi omkhathi noma amalensi e-cosmic.Ngenxa yokuthi i-PC resin iyinto esebenza kahle kakhulu ye-thermoplastic, ilungele ukwenza amalensi engilazi yamehlo.Amalensi e-PC anokumelana nomthelela omuhle kakhulu, cishe awakaze aphuke, futhi aphephe kakhulu ukuwasebenzisa.Ngokwesisindo, alula kunama-resin lens.Kodwa-ke, amalensi e-PC angaba nzima ukuwacubungula, awenze abize kakhulu.
Izinto Ezifanelekayo Zabantu Asebekhulile
Kubantu asebekhulile ababhekene ne-presbyopia, kunconywa ukukhetha amalensi engilazi noma amalensi eresin.I-Presbyopia ngokuvamile idinga izibuko zokufunda ezinamandla aphansi, ngakho-ke isisindo samalensi akuwona ukukhathazeka okubalulekile.Ukwengeza, abantu abadala abavamile ukusebenza kancane, okwenza amalensi engilazi noma amalensi e-resin aqine kakhudlwana ukumelana nokuklwebheka, kuyilapho kuqinisekisa ukusebenza kokubona okuhlala isikhathi eside.
Izinto Ezifanelekayo Zabantu Abadala
Amalensi e-resin afaneleka kubantu abadala abaphakathi nabasebasha.Amalensi e-resin anikeza izinhlobonhlobo zezinketho, okuhlanganisa ukuhlukanisa okusekelwe kunkomba ye-refractive, ukusebenza, kanye namaphoyinti okugxilwe kuwo, ngaleyo ndlela ahlangabezane nezidingo ezihlukahlukene zamaqembu ahlukene.
Indaba Efanelekayo Yezingane Nentsha
Lapho ukhetha izibuko zezingane, abazali bayelulekwa ukuba bakhethe amalensi enziwe ngezinto ze-PC noma ze-Trivex.Uma kuqhathaniswa nezinye izinhlobo zamalensi, lezi zinto zokusebenza azisindi nje kuphela kodwa futhi zinikeza ukumelana nomthelela ongcono nokuphepha okuphezulu.Ukwengeza, amalensi e-PC kanye ne-Trivex angavikela amehlo emisebeni ye-UV eyingozi.
Lawa ma-lens aqinile ngokwedlulele futhi awaphuki kalula, ngakho abizwa ngokuthi amalensi okuphepha.Inesisindo esingamagremu angu-2 kuphela ku-cubic centimeter ngayinye, okwamanje ayizinto ezilula kakhulu ezisetshenziselwa amalensi.Akufanelekile ukusebenzisa amalensi engilazi ezingilazini zezingane, njengoba izingane ziyasebenza futhi amalensi engilazi ajwayele ukuphuka, okungase kulimaze amehlo.
Ekuphetheni
Izici zomkhiqizo zamalensi enziwe ngezinto ezahlukahlukene zihluke kakhulu.Amalensi engilazi asindayo futhi anesici sokuphepha esiphansi, kodwa awakwazi nokuklwebheka futhi anesikhathi eside sokuwasebenzisa, okuwenza afanelekele abantu asebekhulile abanamazinga aphansi okusebenza komzimba kanye ne-presbyopia encane.Amalensi e-resin eza ngezinhlobonhlobo eziningi futhi anikeza ukusebenza okuphelele, okuwenza afanelekele izifundo ezihlukahlukene kanye nezidingo zomsebenzi zabantu abaneminyaka ephakathi nentsha.Uma kuziwa ezingilazini zamehlo zezingane, ukuphepha okuphezulu nokukhanya kuyadingeka, okwenza amalensi e-PC abe yisinqumo esingcono.
Ayikho into engcono kakhulu, kuphela ukuqwashisa okungaguquki ngempilo yamehlo.Lapho sikhetha amalensi enziwe ngezinto ezihlukahlukene, kumelwe sicabangele ngokombono womthengi, sikhumbula izimiso ezintathu zokufakwa kwezibuko zamehlo: ukunethezeka, ukuqina, nokuzinza.
