Ngakho-ke ake sibheke ngokushesha ukuthi kuyini ukukhanya okuluhlaza okwesibhakabhaka.
I-Short-wave eluhlaza okwesibhakabhaka ukukhanya okunamandla aphezulu kunobude obuphakathi kuka-400nm no-480nm.Ukukhanya okuluhlaza okwesibhakabhaka kulobu bude bamaza kuzokwandisa inani lobuthi endaweni ye-macular yeso, okusongela kakhulu impilo yethu ye-fundus.Ukukhanya okuluhlaza okwesibhakabhaka kukhona enanini elikhulu lama-computer monitors, izibani ze-fluorescent, amafoni omakhalekhukhwini, imikhiqizo yedijithali, izikrini zokubonisa, i-LED nokunye ukukhanya, ubude be-wavelength bokukhanya okuluhlaza okwesibhakabhaka buzokwenza i-eye macular area toxin yanda, usongo olukhulu empilweni yethu yamehlo.
Ukukhanya okuluhlaza okwesibhakabhaka kubonakala yonke indawo ekuphileni kwansuku zonke, kodwa umthombo oyinhloko wokuchayeka kokukhanya okuluhlaza okulimazayo izikrini ze-LED LCD.Izikrini ze-LCD zanamuhla zikhanyiswa yi-LEDS.Njengoba ukukhanya kwangemuva kudinga umphumela wokukhanya okumhlophe, imboni isebenzisa amaledi aluhlaza axutshwe namaphosphor aphuzi ukuze kwakhe ukukhanya okumhlophe.Ngenxa yokuthi amaledi aluhlaza ucezu oluyinhloko lwehadiwe, i-spectrum eluhlaza okwesibhakabhaka yalokhu kukhanya okumhlophe ine-crest, idala inkinga yalokho esikubiza ngokuthi ukukhanya okuluhlaza okulimazayo okulimaza amehlo.
Okokuqala, indima yangempela ye-anti blue light lens:
Kulabo abachitha isikhathi esiningi besebenzisa amakhompiyutha noma izibonisi ze-elekthronikhi, manje sekuqinisekile ukuthi ama-lens avimbela i-blue angavimba okunye ukukhanya okuluhlaza okulimazayo emehlweni, okwenza kube lula ukusebenza phambi kwesikrini sekhompyutha.Kodwa-ke, abukho ubufakazi obengeziwe bokufakazela ukuthi kungathuthukisa ngempumelelo umphumela wokuvuvukala kwamehlo omuncu, iso elomile, ukulahlekelwa umbono, izilonda ze-fundus nokunye.Ngakho-ke qaphela izimangalo zokumaketha eziyihaba.
Okwesibili, imininingwane idinga ukunakwa esivivinyweni:
1. Amapharamitha asetshenziswa kakhulu esikhathini esizayo esiseduze
Njengoba izibuko zisetshenziswa ngokuyinhloko muva nje, imiyalelo ye-optometry kufanele icabangele lokhu ngokugcwele futhi inciphise ngokufanele ukucindezelwa okubukwayo okulungisiwe ngesikhathi se-optometry, ukuze kugwenywe ukungakhululeki kwamehlo okubangelwa isikhathi eside sokusetshenziswa okuseduze.Umyalelo othize we-Optometry kufanele utholwe udokotela wamehlo ochwepheshe ngemuva kwe-rigory optometry.
2. Amalensi optical afanelekayo
1, amalensi okukhanya aluhlaza okwesibhakabhaka kufanele kuqala abe amalensi okukhanya afanelekayo, futhi kufanele abe nephesenti elithile lomphumela wokukhanya okuluhlaza okwesibhakabhaka, amalensi akhanyayo aluhlaza okwesibhakabhaka ajwayelekile angaba ngu-30%.Akuwona wonke ukukhanya okuluhlaza okuyingozi.Cishe amaphesenti angu-30 okukhanya okuluhlaza abhekwa njengengozi, kanti okunye kuyazuzisa.Kunconywa ukukhetha ama-lens akhiqizwa abakhiqizi be-lens yomkhiqizo omkhulu.
Okwesibili, kunezinhlobo ezimbili eziyinhloko zama-lens anti-blue.Eyodwa amalensi awolintshi akhanyayo anama-substrates a-tinted, njenge-GUNNAR, anengemuva elimnyama futhi angakulungele ukugqokwa isikhathi eside.Ilensi eyisicaba yiyona lens eyinhloko.Okunye kubonakala ngongqimba lwefilimu engaphezulu, umbala wangemuva ulula, kukhona nowolintshi okhanyayo, kulula ukuwubona ngaphansi kwengemuva elimhlophe.Ngokombono womphumela, kukhona umehluko omncane phakathi komphumela wokuvikela ukukhanya okuluhlaza kwezinhlobo ezimbili zamalensi.Kodwa lezi zakamuva zithuthuke kakhulu kwezobuchwepheshe futhi ngokuvamile ziphakeme ekusebenzeni kwe-optical.
Ngaphezu kwalokho, ngisho nabantu abangewona i-myopic, kungcono ukukhetha amalensi omkhiqizo wabakhiqizi abathembekile be-lens optical.Kungcono ukwenza i-lens ngokwehlukana ukuze ukhethe ngokucophelela umkhiqizo oqediwe wezibuko ze-zero degree.Izinga le-lens liyisihluthulelo esibalulekile sokuqinisekisa ukunethezeka nomphumela wokugqoka.
3. Phatha umsindo wezimakethe ngokuqapha
Labo abathi banomsebenzi "wokuvikela iso" kanye nalabo abaziqhayisa ngomphumela wemilingo wemikhiqizo yabo yokukhanya okuluhlaza okwesibhakabhaka kusolwa ukuthengisa okukhohlisayo.Labo abasebenzisa inombolo enkulu yezithombe ukusongela ukulimala kokukhanya okuluhlaza ngokusobala basolwa ngokusabisa ukumaketha ukuze bakhulise umonakalo wokukhanya okuluhlaza okwesibhakabhaka.Gwema ukukhuluma ngomkhiqizi wamalensi noma ilensi evela embonini akwaziwa, ungazami.Ukuthengisa kudinga kuphela isikhumba esiwugqinsi kanye nesibindi sokuqhosha, kodwa amafekthri amalensi ochwepheshe adinga iminyaka engaphezu kweshumi noma ngisho namashumi eminyaka enqwabelana, ungaphuphuthekisiwe yizithombe ezikhazimulayo nesithombe somkhiqizo.Njengamanje, akekho umthengisi wezingubo zamehlo emhlabeni onekhono lokuthuthukisa amalensi ochwepheshe.Iningi lezizathu ezinkulu zokuthi baqalise amabhrendi abo yingoba abafuni amakhasimende aqhathanise amanani.
