Ngeeyure ezinde zemini ezindala ezindala zelanga, ezihamba ezitratweni, akukho nzima ukuqaphela ukuba abantu abaninzi banxibe i-lenseschromic lenseds kunangaphambili. I-shumilssussussuss i-shushu iyomjelo okhulayo weRhafu kwishishini lokuThengisa kwamehlo kule minyaka idlulileyo, kunye neelenti zefoto eziqinileyo. Imakethi kunye nokwamkelwa kwabathengi ngee-Photochromic i-lenses stem kwisitayile sabo, ukhuseleko lokukhanya, kunye neemfuno ezinxulumene nokuqhuba.
Kule mihla, abantu abaninzi bayazi malunga nemilinganiselo ye-ultraviolet inokubangela ulusu. Ilanga, i-Parasols, i-caps ye-baseball, kunye ne-Ice Slick Arms igubungela i-ices zibaluleka kokuphuma kwehlobo. I-rays yomonakalo yenziwa emehlweni asenokungabonakali ngokukhawuleza njengolusu olunyibilikisiweyo, kodwa kwixesha elide, ukubonakaliswa okungaphezulu kunokukhokelela kwimiphumo emibi ngakumbi. Izifo zamehlo njengekhathalogu kunye nokuthathwa kwe-sucular enxulumene nobudala bekucacisiwe ukuba ne-Counts ye-Counts ye-Counts kwi-UV ekubonakalisweni. Okwangoku, abathengi baseTshayina abanamxholo umanzi we "xa unxiba i-sunglass" esekwe kwiimeko zelanga. Rhoqo, indawo engaphandle ekhanyayo sele ifuna ukhuseleko lokukhanya, kodwa uninzi lwabathengi baziva ngathi "ngokungeyomfuneko" kwaye bakhetha ukungazinxibi. Ngokuchasene nale minxeba ngasemva, iifoto zefonti, ezibonelela ngokulungiswa kombono kunye nokukhusela ukukhanya ngaphandle kwesidingo sokususwa njengokwamkelwa rhoqo kwiindawo ezahlukeneyo, bafumana ukwamkelwa phakathi kwabantu abaninzi.
Umgaqo wotshintsho kwimibala kwi-Photochromic lenses isekwe kwi "Photochromism." Kwiseto sangaphandle, ezi zelebhu zimnyama ukuba zifake i-slullubs kwaye zibuyise ukuba zicacile kwaye zibonakale ezibonakalayo. Olu phawu lunxulunyaniswa nento eyaziwa ngokuba yi-halide yesilivere. Ngexesha lenkqubo yokuphuhlisa, abavelisi belensi bayangenisa isiseko okanye ifilimu yeelensi ze-lens kunye ne-rocrystals ye-Halide. Xa ityhilwe ekukhanyeni okuqinileyo, i-halide yesilivere ibongoza kwi-ion yeSilivere kunye ne-halide ion, ithathe uninzi lokukhanya kwe-ultraviolet kunye nokukhanya okubonakalayo. Xa ukukhanya kwimo engqongileyo i-Dims, i-ion yesilivere kunye ne-ion ye-halide iphinda ibuyele kwi-helide yesilivere phantsi kwesenzo sokucombulula i-oxide, sibangela ukuba icacile kwaye iphiliswe ngendlela ecacileyo.
UTSHINTSHO LWEZIBONELELO KWI-PARTSHROM le-Lenses sisiphumo so uthotho lwemichiza ephindiweyo, ngokukhanya (kubandakanya ukukhanya kwe-Ultraviolet) ukudlala indima ebalulekileyo kwezi zinto. Ngokwemvelo, ukusebenza kwenkqubo yokutshintsha kwemibala kuphenjelelwa ngamaxesha kunye neemeko zemozulu, ngoko ke ayisoloko igcina isiphumo esisebenzayo nesizinzileyo.
Ngokubanzi, kwimozulu enelanga, ubunzulu beemitha ze-ultraviolet bomelele, bukhokelela kwifolokhwe enzulu yokuphendula, kunye neelebhu kakhulu. Ngokwahlukileyo, kwiintsuku ezinamafu, xa i-UV Rys kunye nobunzulu bokukhanya bayabuthathaka, iilensi zibonakala zilula. Ukongeza, njengoko iqondo lobushushu liyaphuma, umbala weefoto zefolpheni ngokuthe ngcembe kancinci. Kwelinye icala, xa amaqondo obushushu ahla, iilensi zimnyama kancinci. Kungenxa yokuba kumaqondo obushushu aphezulu, i-ions yesilivere kunye ne-ions yesilivere, eyayingalunganga, incitshiswa i-halde yesilivere phantsi kwamandla amakhulu, ukuqaqambisa umbala weelensi.
Ngokuphathelele iilensi zefoto, kukho neminye imibuzo eqhelekileyo kunye namanqaku olwazi:
Ngaba iilensi ze-Photochromic zine-onlighting ephantsi / imvakalo-mali esezantsi ethe yathelekiswa neelensi rhoqo?
I-lenses ephezulu yefoto ingenabala ngokupheleleyo xa ingasebenzi kwaye ayinasikhanyiso esisezantsi sokudlulisela kwiilensi rhoqo.
Kutheni le nto i-Photochchromic lenseds yokutshintsha umbala?
Ukunqongophala kotshintsho kwimibala kwi-Photochromic lenses inxulumene nezinto ezimbini: Iimeko zokukhanyisa kunye ne-Photeromic Agement (i-halide yesilivere). Ukuba abatshintshi umbala nokuba kukukhanya kwe-radiation eyomeleleyo kunye ne-UV, kunokwenzeka ukuba iarhente yefonti yenzekile.
Ngaba ifuthe elitshintshileyo lemibala ye-Photochchromic lensed indala ngokuhamba kwexesha?
Njengaziphi na iilensi rhoqo, iifoto zefolphen zemifanekiso nazo zinemihla ngemihla. Ngononophelo olufanelekileyo, ngokubanzi bahlala ngaphezulu kweminyaka emi-2-3.
Kutheni le nto iifoto zefotochmic ziye zimnyama ngokusisigxina ngokuhamba kwexesha?
Ukuba i-Photochromic lensed Darken ngokuhamba kwexesha kwaye ayinakukwazi ukubuyela umva, kungenxa yokuba iarhente yabo yefoto ingenako ukubuyela kwimeko yalo yoqobo emva kokutshintsha umbala, okukhokelela kwi-tint yentsalela. Le phenonon ixhaphake kakhulu kwiilensi ezisezantsi, ngelixa iifoto ezisemgangathweni ze-Photochromic azinakuba nalo mbandela.
Kutheni le nto i-lense ixhaphakileyo kwintengiso?
Iilensi ezingwevu zinokufumana inzuzo kunye neepesenti ezingama-98 ze-UV. Elona ncedo likhulu lweelensi ezigrey kukuba azitshintshi imibala yoqobo yezinto, ukunciphisa amandla okukhanya. Bayifumana ngokucacileyo zonke izinto ezibonakalayo, ke izinto zibonakala zimnyama kodwa ngaphandle kokugqobhoza umbala, ukubonelela ngombono oyinyani nezemvelo. Ukongeza, i-grey ngumbala ongathathi hlangothi, ilungele wonke umntu, iyenza ithandwa kakhulu kwimarike.
