01, yiniI-lens ye-photochromic?
Amalensi ashintsha umbala (amalensi e-photochromic) amalensi ashintsha umbala esabela ekushintsheni kokuqina kwe-UV kanye nezinga lokushisa.
Amalensi ashintsha umbala enziwa ngokungeza ama-photosensitizer ahlukene (njenge-silver halide, i-silver barium acid, i-copper halide ne-chromium halide) kumalensi eresin avamile.
Ngemuva kokushintshwa kombala kungaba nemibala ehlukene, njengokuthi: itiye, itiye grey, grey njalonjalo.
02, inqubo yokushintsha umbala
Njengamanje, kunezinhlobo ezimbili zobuchwepheshe bokushintsha umbala emakethe: ukuguquguquka kwefilimu nokushintsha kombala kwe-substrate.
A. Ukushintsha umbala kwefilimu
Futha i-ejenti yokushintsha umbala ebusweni belensi, ebonakala ngombala ongemuva okhanyayo cishe ongenambala.
Izinzuzo: ukushintsha umbala ngokushesha, umbala ukushintsha umfaniswano ngaphezulu.
Ukubi: Umphumela wokushintsha umbala ungase uthintwe izinga lokushisa eliphezulu.
B. Ukushintsha umbala kwe-substrate
I-ejenti yokushintsha umbala yengezwe kusengaphambili ekucubungulweni kwezinto ezibonakalayo ze-monomer yelensi.
Izinzuzo: Isivinini sokukhiqiza esisheshayo, imikhiqizo engabizi kakhulu.
Ukungalungi: Umbala wezingxenye ezimaphakathi nezinqenqemeni zamalensi obude zizohluka, futhi ubuhle abufani namalensi ashintsha umbala wefilimu.
03. Ukushintsha kombala kwamalensi ashintshile
Ukuba mnyama nokukhanya kwamalensi ashintsha umbala kuhlobene ngokuyinhloko namandla emisebe ye-ultraviolet, nayo ehlobene eduze nendawo ezungezile kanye nenkathi yonyaka.
Usuku libalele: Umoya ekuseni awunamafu kancane futhi unokuvinjwa okuncane kwe-UV, ngakho-keamalensi photochromicekuseni kuzoba mnyama.Kusihlwa, ukukhanya kwe-ultraviolet kuba buthakathaka futhi umbala we-lens ulula.
Ukusibekela: Nakuba ukukhanya kwe-ultraviolet kubuthakathaka endaweni yokusibekela, kungase futhi kwanele ukufinyelela phansi, ngakho-ke i-lens yokushintsha umbala isengakwazi ukudlala indima ethile yokuvikela, umbala uzoba lula ngokuqhathaniswa endaweni enelanga.
Izinga lokushisa: Ngokuvamile, njengoba izinga lokushisa likhuphuka, umbala welensi eshintshile kancane kancane uyoba lula;Ngokuphambene, njengoba izinga lokushisa lehla, unwabu luba mnyama kancane.
Indawo yasendlini: Ekamelweni, i-lens eshintsha umbala ngeke ishintshe umbala futhi ihlale isobala futhi ingenambala, kodwa uma ithintwa umthombo wokukhanya we-ultraviolet ozungezile, isazoba nomthelela oshintsha umbala, odlala umsebenzi wokuvikela i-ultraviolet ngaso sonke isikhathi.
04. Kungani ukhetha amalensi ashintsha umbala?
Njengoba amazinga e-myopia enyuka, kunesidingo esikhulayo samalensi ashintsha umbala, ikakhulukazi entwasahlobo nasehlobo, lapho ilanga likhanya ngokugqamile nemisebe ye-UV ishubile, engase ilimaze amehlo.
Ngakho-ke, indlela engcono kakhulu yokuvikela amehlo akho emisebeni ye-UV ngenkathi futhi ubhekana nezinkinga zokubonisa umbala ukugqoka izibuko ezishintsha umbala ezinokuvikelwa kwe-UV (izibuko ezishintsha umbala ezine-diopter).
05, izinzuzo zamalensi ashintsha umbala
Isibuko esinezinjongo eziningi, gwema ukukhetha nokugqoka inkinga
Abantu abangaboni ngaso linye kudingeka bagqoke izibuko zelanga uma befuna ukuvimba imisebe yelanga e-ultraviolet ngemva kokuba amehlo abo elungisiwe ngokunqanyulwa.
Amalensi ashintsha umbala izibuko zelanga ezine-diopter.Uma unamalensi ashintsha umbala, awudingi ukuba namapheya amabili ezingilazi lapho uphuma.
Ukufiphaza okuqinile, ukuvimbela ukulimala kwe-UV
Izibuko ezishintsha umbala zingashintsha ngokuzenzakalelayo umbala ngokuvumelana nokukhanya nezinga lokushisa, futhi zilungise ukudluliselwa nge-lens zishintsha umbala, ukuze iso lomuntu likwazi ukuzivumelanisa nokushintsha kokukhanya kwemvelo.
Ngaphezu kwalokho, ingakwazi ukumunca imisebe ye-ultraviolet eyingozi emehlweni abantu, ivimbele ukukhanya nomonakalo olethwa imisebe ye-ultraviolet, inciphise ngempumelelo ukukhanya okukhanyayo, ithuthukise ukunethezeka okubonakalayo, inciphise ukukhathala okubukwayo, ivikele amehlo.
Khulisa umhlobiso, omuhle futhi wemvelo
Amalensi ashintsha umbala afanele indawo yasendlini, yokuhamba, nengaphandle.Akuzona kuphela izibuko zelanga ezivimba ilanga, kodwa futhi namalensi e-myopia/okubona kude akwazi ukulungisa ukubona.
Ifanele imiklamo ehlukahlukene yelensi, ukubukeka kwesitayela, ukuhlangabezana nokuphishekela imfashini eyengeziwe, ukuhlanganisa kanye nokusebenza kokubili.
