Amalensi ashintsha umbala aya ngokuya ethandwa ngenxa yokuthi awagcini nje ngokunikeza ukuvikelwa kwe-UV, kodwa futhi afanele ukugqoka kwansuku zonke.Iphuzu elibaluleke kakhulu ukuhlangabezana nezidingo zamaqembu ahlukene abantu, njenge-presbyopia, i-myopia, ukukhanya okuyisicaba nokunye.
Ngakho-ke, ungathenga kanjani ama-lens amahle okushintsha umbala?
1, bheka ukuguquguquka
Njengamanje, imakethe ihlukaniswe ngokuhlukahluka kwesisekelo kanye nokuhlukahluka kwe-membrane ngokuya ngenqubo yokukhiqiza.
I-Colloquially, ushintsho olubalulekile ushintsho lwefilimu lapho udayi we-chromotropic wengezwa ku-lens material bese kusetshenziswa i-chromotropic ejenti ebusweni belensi.
Ukushintsha umbala koshintsho lwesisekelo ku-lens, futhi ukuguquguquka koshintsho lwe-membrane kusengqimbeni lwe-membrane endaweni ye-lens.
Njengoba ingxenye ye-discolation ye-lens ye-membrane isesendlalelo se-membrane, ayikho ngaphansi kwemingcele yezinto ezibonakalayo.Akunandaba ukuvikelwa kokukhanya okuluhlaza okwesibhakabhaka, indawo evamile ye-aspheric, 1.67, 1.74 high refractive index nokunye, ilensi ye-membrane ingacutshungulwa ibe ilensi yefilimu, futhi abathengi banokukhetha okukhulu.
2, ukufana kombala
Njengamanje, umbala wefilimu oshintsha ilensi ufana nenqubo yokushintsha umbala ngaphandle kokuhluka kombala, ngakho-ke umbala wefilimu oshintsha ilensi unezinzuzo eziningi kanye nomphumela ongcono wokugqoka.
3, umbala ukuzinza
I-chameleon enhle izolungisa ngokuzenzakalelayo ukujula kombala welensi ngokuvumelana nokushintsha kokukhanya, futhi izobuyela esimweni esisobala lapho ingaphakathi endlini, efana nelensi evamile, ukuze kuqinisekiswe ukudluliswa okuphezulu kwelensi.
Umbala ushintsha yonke inqubo ngaphandle kokuzwa, ukushintsha okungenamthungo.
