Ngokukhanya okukhulu kwelanga lasehlotyeni, ukuphuma phandle kudla ngokubangela ukukrwaqula okuzenzekelayo. Ummiseloiindondo zelangakutshanje ibe yindawo ekhulayo yokukhula kwengeniso kwishishini lokuthengisa i-eyewear, ngelixa iilensi ze-photochromic zihlala ziyisiqinisekiso esiqinileyo sokuthengiswa kwehlobo. Intengiso kunye nokwamkelwa kwabathengi kwiilensi zefotochromic zivela kwisitayile sazo, ukhuseleko olulula, kunye nokufaneleka kokuqhuba phakathi kwezinye iimfuno ezahlukeneyo.
1.Kutheni ukhuseleko olubonakalayo luyimfuneko?
Ukukhanya kwe-Ultraviolet kunokwahlulwa ngokulula kwi-UVA, UVB, kunye ne-UVC:
I-UVC inobude obufutshane obufutshane kwaye ifunnwe ngumaleko we-ozone emoyeni, ngoko ayinakukhathazeka.
I-UVB, ukukhanya okuphakathi kwe-ultraviolet, kunokonakalisa iiseli zolusu ngokusabela kweefotochemical, kubangele i-erythema kunye nokutshiswa lilanga.
I-UVA, ukukhanya kwe-ultraviolet yamaza amade, kubangela ngokuthe ngqo ulusu ukuba lube mnyama ngokukhawuleza ngaphandle kokutshisa, kodwa lukhokelela kwiimeko ezifana ne-keratitis.
Kumphezulu woMhlaba, amaza amaza okukhanya e-ultraviolet amaza enza i-97% yokuvezwa kwe-UV. Ke ngoko, ukhuseleko kwi-UVA kunye ne-UVB kubomi bemihla ngemihla lubalulekile.
Enye ingozi litha. Kwimozulu ecacileyo, ngakumbi ehlotyeni, ukukhanya akuchaphazeli nje ukucaca kombono kodwa kubangela ukukhathala kwamehlo.
Ngenxa yale mvelaphi, ukubaluleka kokukhetha iilensi ze-photochromic ezibonelela ngokulungiswa kombono kunye nokukhusela ukukhanya kuyabonakala.
2.Ngaba wonke umntu unokunxibaiilensi photochromic?
Okokuqala, qaphela la maqela alandelayo angafanelekanga kwiilensi zefotochromic:
Abantwana abancinci be-myopic (abangaphantsi kweminyaka emi-6 ubudala) abanamehlo asakhulayo banokuchaphazeleka ngokunxiba ixesha elide.
Abantu abaneglaucoma bafuna ukukhanya okuqaqambileyo. Ukunxiba izibuko zelanga kunciphisa ukukhanya, nto leyo enokwandisa abafundi, inyuse uxinzelelo lwamehlo, kwaye ibangele intlungu.
Abantu abane-optic neuritis, njengoko ukunxiba iilensi zefotochromic kunokonyusa ukuvuvukala ngenxa yokungahambi kakuhle kwemithambo-luvo.
Ukukhanya kwe-UV kuhlala kukho, kungakhathaliseki ixesha lonyaka okanye imozulu. Ngaphandle kwamaqela akhankanywe ngasentla, iiglasi ze-photochromic zifanelekile wonke umntu.
3.Kutheni iilensi ezingwevu zezona zixhaphakileyo kwimarike?
Iilensi ezingwevu zinokufunxa i-infrared kunye ne-98% yemitha ye-UV. Inzuzo ephambili yeelensi ezingwevu kukuba aziyitshintshi imibala yokuqala yendawo engqongileyo, ngokufanelekileyo ukunciphisa ukukhanya kokukhanya. Iilensi ezingwevu zibonelela ngokufunxa okulinganayo kuzo zonke iispectrums, ngoko ke izinto zibonakala zimnyama kodwa ngaphandle kokugqwetheka okubalulekileyo kombala, zinika umbono wokwenyani wendalo. Ukongezelela, igrey ngumbala ongathathi hlangothi ofanelekileyo kumntu wonke, okwenza ukuba idume ngakumbi.
4. Izinto eziluncedo kwisiseko esicacileyo,iilensi ezichasene neblue photochromic?
Ilungele iimeko ezahlukeneyo zobomi, ukutshintsha ngaphandle komthungo phakathi kwangaphakathi nangaphandle, isebenzela iinjongo ezimbini.
Ngaphakathi/ebusuku zicacile kwaye ziselubala, ngaphandle ziba mnyama, zinika ukhuseleko oluphindwe kabini kwimitha ye-UV kunye nokukhanya okuluhlaza okuyingozi, kuthomalalisa ukudinwa.
Ubuchwephesha obugqwesileyo bokutshintsha ifilimu buqinisekisa utshintsho olukhawulezayo noluzinzileyo lombala; Itekhnoloji yokukhanya ye-nano anti-blue igcina iilensi zicacile kwaye zingekho tyheli, ziqinisekisa umbono okhululekileyo.
Njengoko intetho isithi, "Ukwenza umsebenzi olungileyo, umntu kufuneka aqale alole izixhobo zakhe." Inkxaso yezinto eziphathekayo: iisampulu zefotochromic, iipropu, kunye neepowusta ze-lightbox zincedisa ekukhuthazeni iilensi ze-photochromic.
Ukuthuthuzela, ukukhuselwa, kunye nokulula ngamanqaku amathathu afuna ukuqiniswa ngokuphindaphindiweyo xa unxibelelana nabathengi.
5.Isiseko esicacileyo,iilensi ezichasene neblue photochromicifaneleke ngakumbi ukugcinwa?
Esinye sezona zihloko zishushu kwimpilo yamehlo ngoku kukukhusela ukukhanya okuluhlaza okwesibhakabhaka, kunye neelensi ezisebenzayo ezinokukhanya okuchasene nokukhanya okuluhlaza okwesibhakabhaka zithandwa kakhulu ngabathengi. Umonakalo we-UV yinkxalabo yonyaka wonke kodwa uvakaliswa ngokukodwa kwiinyanga ezishushu zasehlotyeni, ngoko ke imfuno yeelensi ze-photochromic ixesha elide.
Nangona iilensi zephotochromic zifumaneka ngemibala eyahlukeneyo, iilensi ezingwevu zifaneleke kakhulu ukugcinwa. Ngaphandle, ingwevu enzulu ngowona mbala ukhululekileyo emehlweni; zihambelana nefashoni kunye nayo nayiphi na ifreyimu yeglasi yamehlo, nto leyo ezenza ukuba zibe lukhetho oluguquguqukayo lwemibala yefotochromic.
Ukunikezelwa kokukhethwa kwee-indices ezininzi ze-refractive, i-1.56 kunye ne-1.60 i-refractive index photochromic lens ithengisa kakhulu kwiivenkile. Ukwandisa umlinganiselo wentengiso yoKhuseleko loKhuseleko lwe-1.60 i-anti-blue light photochromic lens ayincedi nje kuphela ukunyusa i-avareji ye-odolo yexabiso kodwa ineenzuzo ezicacileyo eziququzelela ukuthengiselana. Ukufumana imigaqo-nkqubo ye-inventri eyongezelelweyo kunye nenkxaso yokuthengisa emva kokuthengiswa kuKhuseleko loKhuseleko olucacileyo-isiseko se-anti-blue light photochromic lens, nceda uqhagamshelane nommeli weentengiso.
6.Imisebenzi yemibala eyahlukeneyo yeiilensi photochromic?
| Umbala weTea | Ukuphucula ngokufanelekileyo ukungafani okubonakalayo kunye nokucaca, kusebenza kakuhle kwiimeko ezingcolileyo okanye ezinenkungu, kwaye lukhetho olufanelekileyo kubaqhubi kunye nezigulana eziphezulu. |
