1.56 Bifocal Round Top Photochromic Gray HMC lens Optical

Incazelo emfushane:

Izingilazi ze-bifocal zilungele ukusetshenziswa kwasebekhulile, futhi zingakwazi ukubona eduze nakude. Lapho abantu beguga, amehlo abo ayofiphala futhi amehlo abo ayoba abi. Futhi izibuko ze-bifocal zingasiza asebekhulile ukuba babone kude futhi babone eduze.

Ilensi ekabili ibizwa nangokuthi i-bifocal lens, ehlanganisa ikakhulukazi ilensi eyisicaba engaphezulu, ilensi engaphezulu eyindilinga namalensi angabonakali.

Amalensi ezingilazi ze-bifocal ayadingeka ukuze afake i-hyperopia diopter, i-myopia diopter noma ukukhanya okuphansi. Ibanga elikude le-pupillary, eduze nebanga lomfundi.

Ngokomgomo we-photochromic reciprocal reversible reaction, ingaba mnyama ngokushesha ngaphansi kokukhanya kwelanga nemisebe ye-ultraviolet, imunce ngokuphelele ukukhanya kwe-ultraviolet, futhi ibambe ukukhanya okubonakalayo ngendlela engathathi hlangothi; Emuva endaweni emnyama, ingabuyisela ngokushesha ukukhanya okungenambala. Isetshenziswa kakhulu ezindaweni zokusebenza zangaphandle, ezineqhwa nezasendlini ezinemithombo yokukhanya enamandla ukuze kuvinjelwe ukulimala kwamehlo okubangelwa ukukhanya kwelanga, ukukhanya kwe-ultraviolet nokuxhopha.

Ilensi eshintsha umbala ingalungisa ukushintsha kombala ngokujula kokukhanya kwe-ultraviolet. Uma ukukhanya kwe-ultraviolet kunamandla, umbala uba mnyama. Ngokuphambene nalokho, ukukhanya kwe-ultraviolet kuba buthaka, umbala ungashoni kakhulu uzobonakala. Isimiso siwukuthi izinhlayiya zesiliva ze-halide zengezwa ku-lens izinto zokusetshenziswa, futhi i-halide yesiliva ichithwa ibe ama-halogen ions nama-ion esiliva ngaphansi kwesenzo se-lens. ukukhanya kwe-ultraviolet ukushintsha umbala.

Isingeniso Sokukhiqiza

1. Ijubane lokushintsha kombala: Uma ilensi enhle yokushintsha umbala ihlangana nokukhanya kwe-ultraviolet ngaphandle, ijubane lokushintsha umbala lishesha kakhulu, futhi lifiphala ngokushesha ngaphakathi endlini.

2. Ukujula kokushintsha kombala: uma umsebe we-ultraviolet welensi eshintsha umbala unamandla, ukushintsha kombala kuzojula. Ukushintsha kombala kwelensi evamile yokushintsha umbala kungase kungabi kuhle uma kuqhathaniswa.

3. Ipheya lamalensi ashintsha umbala anedigri efanayo noma ulwelwesi lwamalensi ashintshayo, kanye nejubane elishintsha umbala nokujula kwamalensi amabili ngokuyisisekelo kuyafana. Akufanele kube khona omunye onokushintsha kombala ojulile kanye noshintsho lombala okhanyayo
