Lub caij ntuj sov yog scorching kub, npaj lub me me mus so rau lub sij hawm mus so tawm cov phooj ywg kom tau yooj yim mus tawm mus txaus siab rau lub hnub ci.Tab sis rau cov phooj ywg uas hnav tsom iav, tab sis qhov muag photophobia, tsis tuaj yeem ua raws lub siab mus hnav looj tsom iav dub lossis yuav tsum hnav ob lub tsom iav ntawm kev ntxhov siab.
Muaj ntau hnav cov tsom iav myopic ntawm tus khub me me, lub caij nplooj ntoos hlav lub caij ntuj sov muaj mob taub hau tsis tu ncua: dua li myopic yuav ua li cas hnav looj tsom iav dua yuav tsum tiv thaiv lub hnub?Txhua hnub Commute sunscreen daim tawv nqaij tiv thaiv qhov muag yuav ua li cas?Myopic tsav yuav ua li cas ntxiv?
Ua tib zoo saib daim duab saum toj no.Koj puas xav hnav tsom iav tinted nrog dioptre tus lej ntawm lawv, lossis tsom iav nrog cov tsom iav hauv lawv?
Nyob rau hauv lub kub kub los yog lub teeb reflection loj snow, dej, lub teeb yuav ua tau zoo stimulation rau lub qhov muag.Nyob rau lub sijhawm no, tib neeg feem ntau xaiv cov looj tsom iav dub kom txo tau lub teeb rau lub qhov muag ntawm qhov stimulation.
Tab sis thaum tib neeg hnav looj tsom iav dub, hauv chav tsaus ntuj yuav tsis pom cov khoom thiab ib puag ncig, tshwj xeeb tshaj yog rau cov phooj ywg uas pom luv luv, nws tsuas yog "ob lub qhov muag dub", cov looj tsom iav dub tsis yooj yim li.Yog li ntawd, txoj hauv kev zoo tshaj los tiv thaiv koj ob lub qhov muag los ntawm UV puas thaum tseem saib xyuas cov teeb meem refractive yog hnav uv-resistant tinted tsom iav.Cov iav hloov xim yog qhov yooj yim thiab siv tau tsom iav, tab sis koj paub vim li cas Lens yuav hloov xim?Qhov zoo ntawm cov iav hloov xim yog dab tsi?
1, Vim li cas thiaj tuaj yeem chromotropic Lens Hloov Xim?
Xim Hloov Cov Lens, tiag tiag hu ua Photochromic Lens, yog lo ntsiab muag uas hloov xim nyob ntawm qhov siv ntawm ultraviolet lub teeb thiab kub.Nws yog nyob rau hauv lub zoo tib yam resin lo ntsiab muag ntxiv cov duab sib txawv, xws li nyiaj Halide, nyiaj barium acid, tooj liab halide thiab chromium halide.Tom qab hloov xim tuaj yeem ua xim sib txawv, xws li tawny, Tawny Grey, grey thiab lwm yam.
Txoj cai ntawm discoloration:
Thaum lub lens discoloration yog tsim, qhov tsim nyog tus nqi ntawm cov nyiaj halide yog ntxiv raws li cov photosensitizer.Silver Halide yog IONIC compound ntawm Halogen thiab nyiaj.Cov nyiaj halide tam sim no nyob rau hauv daim iav hloov xim yog ib qho siv lead ua me me nrog cov khoom me me thiab sib txawv hauv lub Lens.Vim tias tsis sib xws thiab me me, yog li thaum lub teeb irradiation, feem ntau tsis tshwm sim rau qhov tshwm sim.Qhov no kuj ua rau cov tsom iav tinted zoo li pom tseeb thiab pob tshab li cov iav niaj hnub.Thaum illuminated los ntawm lub teeb (tshwj xeeb tshaj yog luv-yoj lub teeb), cov nyiaj halide molecules nyob rau hauv lub Lens tawg mus rau hauv cov nyiaj thiab halogen atoms, uas muaj kev cuam tshuam los yog tawg lub teeb, lub tsub zuj zuj ntawm ntau nyiaj atoms ua rau lub lo ntsiab muag pom lub teeb dub, los yog grey. .
Lub Lens hloov xim yog ib qho khoom.Txawm hais tias cov nyiaj halide siv lead ua yuav decompose nyob rau hauv lub teeb muaj zog, cov nyiaj thiab halogen atoms tsim los ntawm cov tshuaj tiv thaiv nyob ze rau ib leeg thiab yuav tsis khiav, thaum lub teeb nres, nws thim rov qab mus rau lub silver halide xeev tam sim ntawd, yog li ua rau lub lens pob tshab. dua.Tsis tas li ntawd, ib qho me me ntawm tooj liab oxide tau ntxiv rau cov xim hloov cov Lenses, uas ua raws li cov catalyst thiab ua kom cov nyiaj halide decomposition nyob rau hauv lub zog illumination.
2, Discoloration Technology ntawm Discoloration Lens
Tam sim no, feem ntau muaj ob hom kev hloov xim ntawm kev ua lag luam: Zaj duab xis xim-hloov thiab substrate xim-hloov.
Film discoloration "： hais txog qhov chaw ntawm lub lens txheej discoloration tus neeg saib xyuas, tus cwj pwm los ntawm lub teeb tom qab xim ze rau qhov tsis muaj xim, tseem hu ua spin-coated zaj duab xis hloov.
Qhov zoo: hloov xim sai, xim hloov ntau yam.
Disadvantages: ntsib cov xim kub kub tuaj yeem cuam tshuam rau qee yam.Vim tias qhov nthuav dav coefficient ntawm cov xim hloov xim tsis zoo ib yam li cov yeeb yaj kiab ua haujlwm ntawm lub ntsej muag ntawm Lens, zaj duab xis May Crack nyob rau hauv lub sij hawm ntev kub hloov (sab hauv tsev thiab sab nraum zoov hloov).
Substrate discoloration ": yog nyob rau hauv cov khoom siv lens monomer raw khoom ua txuas twb tov ua ntej ntawm lub sij hawm nyob rau hauv tus neeg sawv cev discoloration.
Qhov zoo: ceev ceev ntau lawm, cov khoom lag luam zoo.
Qhov tsis zoo: Qhov siab ntawm Lens thiab qhov nruab nrab ntawm ntug ntawm cov xim yuav txawv, qhov kev zoo nkauj tsis zoo li zaj duab xis chromotropic Lens.
3 、 Hloov cov xim ntawm lub lens discoloration
Kev tsaus ntuj thiab ci ntsa iab ntawm cov xim hloov cov lo ntsiab muag yog feem ntau cuam tshuam nrog kev siv ntawm ultraviolet hluav taws xob, thiab kev siv ntawm ultraviolet hluav taws xob kuj muaj feem xyuam rau ib puag ncig thiab lub caij.
Sunny Hnub: Thaum sawv ntxov huab cua nyias nyias, tsawg dua UV thaiv, yog li ntawd, thaum sawv ntxov ntawm cov xim hloov Lens yuav tsaus dua.Thaum yav tsaus ntuj, UV lub teeb tsis muaj zog thiab cov lo ntsiab muag sib dua.
Overcast: UV lub teeb tsis muaj zog rau hnub dhau los, tab sis nws tseem tuaj yeem ncav cuag hauv av, yog li cov lo ntsiab muag tseem tuaj yeem hloov xim los tiv thaiv koj, ua rau nws sib zog dua hnub ci.
Kub: nyob rau hauv ib txwm kub tej yam kev mob, raws li qhov kub thiab txias, cov xim ntawm cov xim-hloov lo ntsiab muag yuav maj mam sib zog vim qhov kub nce;conversely, thaum qhov kub thiab txias, cov xim-hloov lo ntsiab muag yuav maj mam darker.Cias muab, qhov no yog vim hais tias thaum kub siab, cov nyiaj thiab halogen atoms uas twb tau decomposed yuav raug txo kom nyiaj halide dua nyob rau hauv qhov kev txiav txim siab ntawm lub zog, yog li cov xim ntawm lub lens yuav sib dua.———— ———— Qhov no yog vim li cas, thaum lub caij ntuj sov, txawm hais tias UV hluav taws xob yog khaus, qhov kub thiab txias ntawm cov lo ntsiab muag tsis tuaj yeem ua rau cov lo ntsiab muag tsaus, nws lub zog UV yog sib npaug rau lub caij ntuj sov UV raug. , tab sis lub lens nto qhov kub thiab txias yog tsawg, cov xim yuav ntxaum.
Sab Hauv Tsev: Tinted Lenses tsis tshua hloov xim thiab nyob hauv pob tshab thiab tsis muaj xim nyob hauv tsev, tab sis lawv tseem tuaj yeem hloov xim yog tias lawv raug UV teeb, muab kev tiv thaiv UV tam sim.
4, Vim li cas peb thiaj xaiv lo ntsiab muag tinted?
Nrog rau qhov nce ntawm Myopia, tib neeg xav tau ntau thiab ntau dua xim hloov lo ntsiab muag, tshwj xeeb tshaj yog nyob rau lub caij nplooj ntoos hlav thiab lub caij ntuj sov, lub hnub kub, muaj zog ultraviolet rays, nws yuav ua rau lub qhov muag puas.
Ultraviolet hluav taws xob los ntawm lub hnub muab faib ua plaub pawg raws li lub wavelength: UVA, UVB, UVC, UVD.UVA thiab UVB yog cov tseem ceeb uas nkag mus rau hauv huab cua thiab ncav cuag qhov chaw.
UVA, UVA, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB , UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, UVB, tshwj xeeb tshaj yog nyob rau lub caij ntuj sov thiab yav tav su.
Peb lub qhov muag tuaj yeem nqus tau ntau yam ntawm qhov ntev ntawm UV, qhov ntev ntev ntawm kev nqus ntawm UV tuaj yeem ua rau qhov muag puas:
macular degeneration: dhau sij hawm, kev puas tsuaj rau lub qhov muag los ntawm macular degeneration (AMD), thiab yog qhov ua rau muaj hnub nyoog ntsig txog qhov muag tsis pom.NROG NYIAJ RAU UV teeb ua rau muaj kev pheej hmoo ntawm macular degeneration.
CATARACT: Tus kab mob cataract yog huab cua ntawm lub qhov muag ntawm lub qhov muag, ib feem ntawm lub qhov muag uas lub teeb tsom.Kev raug ultraviolet teeb, tshwj xeeb tshaj yog UVB, ua rau muaj kev pheej hmoo ntawm qee yam kab mob cataracts.Nws kwv yees tias 10 feem pua ntawm tag nrho cov mob cataract yog ncaj qha cuam tshuam rau UV raug.
PTERYGIUM (N): Feem ntau hu ua "tus surfer lub qhov muag," PTERYGIUM yog paj yeeb, uas tsis yog mob qog noj ntshav uas tshwm sim ntawm cov txheej txheem conjunctival saum lub qhov muag.Thiab lub teeb ultraviolet tau xav tias yog qhov tseem ceeb.
Heliokeratitis: tseem hu ua corneal Sunburn los yog "snow blindness," Keratitis yog tshwm sim los ntawm lub sij hawm luv luv rau UVB rays.Kev caij ski ntev ntawm lub puam lossis tsis muaj tsom iav zoo tuaj yeem ua rau muaj teeb meem, uas tuaj yeem ua rau tsis pom kev ib ntus.
Yog li ntawd, rau qhov xav tau Sunscreen thiab cov neeg myopic hloov qhov teeb meem rau lub qhov muag tshuaj pleev thaiv hnub yog thawj qhov kev xaiv ntawm cov xim hloov lo ntsiab muag.
