Ngesikhathi esandayo amahora okukhanya kwelanga nokukhanya kwelanga okukhulu, ukuhamba emigwaqweni, akunzima ukubona ukuthi abantu abaningi bagqoke ama-PhotoChromic lens kunangaphambili. Izibuko ezinikezwayo ziye zaba umfudlana wemali ekhulayo embonini yezitolo zakwa-Eyewear eminyakeni yamuva, futhi amalensi we-photochromic ahlala eqinile yokuthengisa ehlobo. Imakethe nokwamukelwa kwabathengi kwamalensi we-PhotoChromic lens Stem kusuka esitayeleni sabo, ukuvikelwa okukhanyayo, kanye nezidingo ezihlobene nokushayela.
Kulezi zinsuku, abantu abaningi bayazi ukuthi imisebe ye-ultraviolet ingadala isikhumba. I-sunscreen, ama-parasols, ama-baseball cap, kanye nesembozo se-Ice Silk Arm sibe yizinto ezibalulekile zokuphuma ehlobo. Imisebe ye-UV ye-UV eyenzi emehlweni kungenzeka ingabonakali ngokushesha njengesikhumba esivunyiwe, kepha esikhathini eside, ukubonakaliswa ngokweqile kungaholela emiphumeleni emihle kakhulu. Izifo zamehlo ezinjenge-cataracts kanye nokuwohloka kweminyaka okuhlobene nobudala sekufakiwe ukuthi kube nezixhumanisi eziqondile noma ezingaqondile ekubonisweni kwe-UV. Njengamanje, abathengi baseShayina abanawo umqondo ohlanganisiwe we- "Nini ukugqoka izibuko" ezisuselwa ezimweni zelanga. Imvamisa, imvelo yokukhanyisa yangaphandle isivele idinga ukuvikelwa okukhanyayo, kepha iningi labathengi linomuzwa wokuthi "lingenasidingo" futhi likhetha ukungawagqoki. Ngokumelene nalesi sangemuva, ama-PhotoChromic lens, enikeza womabili ukulungiswa kokubona nokuvikelwa kokukhanya ngaphandle kwesidingo sokususwa njengezibuko ezijwayelekile ezingezansi kwezilungiselelo ezijwayelekile, zithola ukwamukelwa phakathi kwabantu abaningi.
Umgomo wokushintsha kombala ku-PhotoChromic Lens ususelwa ku- "Photochromism." Kuzilungiselelo zangaphandle, la malensi amnyama ukufana nokubulawa kwezibuko futhi abuyiselwe ekucaceni nasezintweni ezibonakalayo. Lesi sici sixhumene nento eyaziwa ngokuthi yi-halide yesiliva. Ngesikhathi sokukhiqiza, abakhiqizi be-lens bafaka isisekelo noma ungqimba lwefilimu lwamalensi nge-microcrystals yesiliva ye-halide. Lapho kuvezwa ukukhanya okuqinile, i-halide yesiliva ibola ibe yisiliva nama-ulide ion, idonsa iningi lokukhanya kwe-ultraviolet kanye nokukhanya okubonakalayo. Lapho ukukhanya emvelweni kufiphala, ama-ion esiliva nama-halide ion abuyisela ku-halide wesiliva ngaphansi kwesenzo se-Copper oxide, okwenza umbala welensi unciphise aze acace futhi acace futhi.
Ukushintshwa kombala ku-PhotoChromic Lens kungumphumela wochungechunge lokuvuselelwa kwamakhemikhali okuguqukayo, ngokukhanya (kufaka phakathi ukukhanya okubonakalayo nokubonakalayo) okudlala indima ebalulekile kulokhu kusabela. Ngokwemvelo, ukusebenza ngempumelelo kwenqubo eshintsha umbala kuthonywa izinkathi zonyaka kanye nezimo zezulu, ngakho-ke akuhlali zigcina umphumela oguquguqukayo futhi ozinzile.
Ngokuvamile, esimweni sezulu esishisayo, ubukhulu bemisebe ye-ultraviolet inamandla, okuholela ekuphenduleni kwe-photochromic kakhulu, futhi amalensi amnyama kakhulu. Ngokuphambene nalokho, ezinsukwini ezingamafu, lapho imisebe ye-UV kanye nokukhanya okukhanyayo kubuthakathaka, amalensi abonakala elula. Ngokwengeziwe, njengoba izinga lokushisa likhuphuka, umbala we-photochromic lens kancane kancane ukhanye. Ngakolunye uhlangothi, lapho izinga lokushisa lehla, amalensi amnyama kancane kancane. Lokhu kungenxa yokuthi emazingeni okushisa aphezulu, ama-ion esiliva nama-halide ion, obekubolile ngaphambili, ancishisiwe abuyele emuva kwi-halide yesiliva ngaphansi kwamandla aphezulu, akhanyise umbala wamalensi.
Mayelana namalensi we-PhotoChromic, kukhona neminye imibuzo evamile namaphuzu olwazi:
Ingabe ama-lens we-PhotoChromic ane-transmittance ephansi yokukhanya / ukucaciswa okuqhathaniswa namalensi ajwayelekile?
Ama-lens asezingeni eliphakeme angenamibala ngokuphelele angenamibala ngokuphelele uma awenziwe asebenze futhi awunawo ukudluliselwa okuphansi okuphansi kunamalensi ajwayelekile.
Kungani ama-PhotoChromic Lens aguqula umbala?
Ukuntuleka kombala we-PhotoChromic Lens kuhlobene nezici ezimbili: Izimo zokukhanyisa kanye ne-PhotoChromic Agent (Halide yesiliva). Uma bengashintshi umbala ngisho nasekukhanyeni okuqinile kanye nemisebe ye-UV, kungenzeka ukuthi i-PhotoChromic Agent yonakalisiwe.
Ngabe umphumela oguqula umbala we-photochromic lens ukhule ngokuhamba kwesikhathi?
Njenganoma yimaphi ama-lens ajwayelekile, ama-lens we-PhotoChromic nawo anawo impilo yonke. Ngokunakekelwa okufanele, ngokuvamile bahlala iminyaka engaphezu kuka-2-3.
Kungani ama-photochromic lens eba mnyama unomphela ngokuhamba kwesikhathi?
Uma ama-PhotoChromic lens enza mnyama ngokuhamba kwesikhathi futhi akwazi ukubuyela emuva ngokuphelele, ngoba i-ejenti yabo ye-photochromic ayikwazi ukubuyela esimweni sayo sokuqala ngemuva kokushintsha umbala, okuholele ekushintsheni kombala, okuholela ekushintsheni kombala. Le nto ivame kakhulu ngamalensi asezingeni eliphansi, kanti amalensi we-photochromic amahle ngeke abe nalolu daba.
Kungani amalensi ampunga ajwayelekile emakethe?
Ama-lens ampunga angadonsa infrared kanye ne-98% ye-UV ray. Inzuzo enkulu yama-lens grey ukuthi awaguquki imibala yasekuqaleni yezinto, ukunciphisa ngamandla akhanyayo. Bamunca ukukhanya ngokulinganayo kuwo wonke ama-spectrums, ngakho-ke izinto zivela mnyama kepha ngaphandle kokuhlanekezela kombala okubalulekile, ukuhlinzeka ngombono weqiniso nowemvelo. Ngokwengeziwe, grey kuyindlela yokungathathi hlangothi, elungele wonke umuntu, okwenza ukuthi ithathwe kakhulu emakethe.
