Ngoko ke masijonge ngokukhawuleza ukuba yintoni ukukhanya okuluhlaza.
Ukukhanya okuluhlaza okwamaza amafutshane kukukhanya okunamandla aphezulu kunye nobude obuphakathi kwe-400nm kunye ne-480nm.Ukukhanya okuluhlaza okwesibhakabhaka kobu bude bamaza kuya kwandisa umthamo wetyhefu kwindawo ye-macular yeliso, isoyike kakhulu impilo yethu ye-fundus.Ukukhanya okuluhlaza okwesibhakabhaka kukho kwinani elikhulu leemonitha zekhompyutheni, izibane ze-fluorescent, iifowuni eziphathwayo, iimveliso zedijithali, izikrini zokubonisa, i-LED kunye nolunye ukukhanya, ubude bokukhanya okuluhlaza okwesibhakabhaka kuya kwenza i-toxin yendawo ye-eye macular yanda, ingozi enkulu kwimpilo yamehlo ethu.
Ukukhanya okuluhlaza okwesibhakabhaka kunokubonwa kuyo yonke indawo kubomi bemihla ngemihla, kodwa owona mthombo wokuvezwa kokukhanya okuluhlaza okuyingozi zizikrini ze-LCD ze-LED.Izikrini ze-LCD zanamhlanje zikhanyiselwe yi-LEDS.Ekubeni ukukhanya kwasemva kufuna ukukhanya okumhlophe, imboni isebenzisa iiledi eziluhlaza okwesibhakabhaka ezixutywe ne-phosphors ephuzi ukwenza ukukhanya okumhlophe.Ngenxa yokuba iilethi eziluhlaza ziyinxalenye ephambili ye-hardware, i-spectrum eluhlaza okwesibhakabhaka yokukhanya okumhlophe ine-crest, idala ingxaki yento esiyibiza ngokuba kukukhanya okuluhlaza okulimazayo okwenzakalise amehlo.
Enye, indima yokwenyani ye-anti blue light lens:
Kwabo bachitha ixesha elininzi besebenzisa iikhomputha okanye iziboniso ze-elektroniki, ngoku kuqinisekileyo ukuba iilensi ezibhlowu ezibhlowu zinokuvala ukukhanya okuluhlaza okuyingozi emehlweni, okwenza kube lula ngakumbi ukusebenza phambi kwesikrini sekhompyuter.Nangona kunjalo, abukho ubungqina obungakumbi bokubonisa ukuba kunokuphucula ngokufanelekileyo umphumo wokudumba kwamehlo omuncu, iso elomileyo, ukulahleka kombono, izilonda ze-fundus njalo njalo.Ngoko lumkela amabango okuthengisa okubaxo.
Okwesibini, iinkcukacha kufuneka zithathelwe ingqalelo kuvavanyo:
1. Iiparamitha zisetyenziswa kakhulu kwixesha elizayo elikufutshane
Njengoko iiglasi zisetyenziswa kutshanje, imiyalelo ye-optometry kufuneka ithathele ingqalelo ngokupheleleyo kwaye inciphise ngokufanelekileyo i-acuity ebonakalayo echanekileyo ngexesha le-optometry, ukwenzela ukuba ugweme ukungahambi kakuhle kwamehlo okubangelwa ixesha elide lokusetyenziswa kufutshane.Umyalelo othile we-optometry kufuneka ufunyanwe ngugqirha wamehlo oqeqeshiweyo emva kwe-optometry engqongqo.
2. Iilensi zamehlo ezifanelekileyo
I-1, iilensi zokukhanya eziluhlaza okwesibhakabhaka kufuneka kuqala zibe neelensi zamehlo ezifanelekileyo, kwaye kufuneka zibe nepesenti ethile yesiphumo sokukhanya okuluhlaza okwesibhakabhaka, iilensi eziqhelekileyo ezichasene nokukhanya okuluhlaza malunga ne-30%.Ayizizo zonke izibane eziluhlaza eziyingozi.Malunga nama-30 ekhulwini okukhanya okuluhlaza kugqalwa kuyingozi, yaye okunye kuyingenelo.Kucetyiswa ukuba ukhethe iilensi eziveliswe ngabavelisi beelensi zophawu olukhulu.
Okwesibini, kukho iindidi ezimbini eziphambili zeelensi ezichasene neblue.Enye i-lens e-orenji ekhanyayo kunye ne-substrates e-tinted, njenge-GUNNAR, enemvelaphi emnyama kwaye ayifanelekanga ukunxiba ixesha elide.Ilensi ecaba yeyona iphambili.Enye ibonwa ngomgangatho wefilimu engaphezulu, umbala ongasemva ukhaphukhaphu, kukwakho neorenji encinci ekhanyayo, kulula ukuyibona phantsi kwemvelaphi emhlophe.Ngokombono wesiphumo, kukho umahluko omncinci phakathi kwesiphumo sokukhusela ukukhanya okuluhlaza kweentlobo ezimbini zeelensi.Kodwa ezi zamva zihambele phambili ngakumbi kwezobuchwephesha kwaye ziphezulu ngokubanzi ekusebenzeni kwe-optical.
Ukongezelela, nakubantu abangenayo i-myopic, kungcono ukhethe iilensi ze-brand zabakhiqizi abathembekileyo bee-lens optical.Kungcono ukwenza i-lens ngokwahlukileyo ukuze ukhethe ngononophelo imveliso egqityiweyo yeeglasi ze-zero degree.Umgangatho we-lens uyisitshixo esibalulekileyo sokuqinisekisa induduzo kunye nefuthe lokugqoka.
3. Yiphathe ngononophelo ingxolo yemarike
Abo bathi banomsebenzi "wokukhusela amehlo" kunye nabo baqhayisa ngempembelelo yomlingo yeemveliso zabo ezichasene nokukhanya okuluhlaza okwesibhakabhaka bakrokreka ukuba bathengisa ngokukhohlisa.Abo basebenzisa inani elikhulu lemifanekiso ukusongela umonakalo wokukhanya okuluhlaza ngokucacileyo bakrokrelwa ngokusongela ukuthengisa ukukhulisa umonakalo wokukhanya okuluhlaza okwesibhakabhaka.Kuphephe ukuthetha malunga nomenzi we-lens okanye i-lens evela kwishishini ayaziwa, ungazami.Ukuthengisa kufuna kuphela ulusu olungqingqwa kunye nobuganga bokuqhayisa, kodwa iifektri zeelensi zobuchwephesha zifuna ngaphezulu kweminyaka elishumi okanye amashumi eminyaka yokuqokelela, musa ukumfamekiswa yimifanekiso eqaqambileyo kunye nomfanekiso webrand.Okwangoku, akukho mthengisi wamehlo kwihlabathi onamandla okuphuhlisa iilensi zobungcali.Uninzi lwezona zizathu zinkulu zokuba baqalise iibrendi zabo kungenxa yokuba abafuni abathengi bathelekise amaxabiso.
