01, yintonilens photochromic?
Iilensi ezitshintsha umbala (i-photochromic lens) ziilensi ezitshintsha umbala ngokuphendula utshintsho kubushushu be-UV kunye nobushushu.
Iilensi ezitshintsha umbala zenziwe ngokongeza ii-photosensitizers ezahlukeneyo (ezifana ne-silver halide, isilivere ye-barium acid, i-copper halide kunye ne-chromium halide) kwiilensi eziqhelekileyo ze-resin.
Emva kokutshintsha kombala kunokuba nemibala eyahlukeneyo, njengale: iti, i-tea grey, i-gray kunye nokunye.
02, inkqubo yokutshintsha umbala
Okwangoku, kukho iintlobo ezimbini zetekhnoloji yokutshintsha umbala kwimarike: ukuguqulwa kwefilimu kunye nokuguqulwa kwe-substrate discoloration.
A. Ukutshintsha kombala wefilimu
Tshiza i-ejenti yokuguqula umbala kumphezulu welensi, ebonakala ngombala ongasemva okhanyayo phantse ongenambala.
Izinto eziluncedo: utshintsho olukhawulezayo lombala, umbala utshintsha ngokulinganayo.
Ukungalungi: Isiphumo sokutshintsha umbala sinokuchaphazeleka bubushushu obuphezulu.
B. Ukutshintsha kombala weSubstrate
I-agent ye-discoloration yongezwa kwangaphambili ekuqhutyweni kwezinto ze-monomer ze-lens.
Izinto eziluncedo: Isantya sokuvelisa ngokukhawuleza, iimveliso ezinexabiso eliphantsi.
Ukungalungi: Umbala weendawo eziphakathi kunye nomphetho weelensi zokuphakama ziya kuhluka, kwaye i-aesthetic ayilunganga njengefilimu ye-discoloration lens.
03. Ukutshintsha kombala kwiilensi ezijikiweyo
Ubumnyama kunye nokukhanya kweelensi ezitshintsha umbala zihambelana ikakhulu nobukhulu bemitha ye-ultraviolet, ekwanxulumene ngokusondeleyo nokusingqongileyo kunye nexesha lonyaka.
Usuku olunelanga: Umoya kusasa awunamafu kwaye unokuthintela okuncinci kwe-UV, ngokoiilensi zephotochromickusasa kuya kuba mnyama.Ngokuhlwa, ukukhanya kwe-ultraviolet kuba buthathaka kwaye umbala we-lens ulula.
Ukusibekela: Nangona ukukhanya kwe-ultraviolet kubuthathaka kwindawo yokusibekela, kunokwanela ukufikelela emhlabeni, ngoko ke i-lens ye-discoloration isenokuthi idlale indima ethile yokukhusela, umbala uya kuba lula kwindawo enelanga.
Ubushushu: Ngokuqhelekileyo, njengoko iqondo lokushisa lisanda, umbala welensi eguquliweyo uya kuba lula kancinci kancinci;Kwelinye icala, njengoko ubushushu behla, ulovane luba mnyama kancinci.
Imeko yangaphakathi: Egumbini, i-lens yokutshintsha umbala ayiyi kutshintsha umbala kwaye ihlale icacile kwaye ingenambala, kodwa ukuba ichatshazelwa ngumthombo wokukhanya kwe-ultraviolet ejikelezileyo, iya kuba nomphumo wokutshintsha umbala, odlala umsebenzi wokukhusela i-ultraviolet ngamaxesha onke.
04. Kutheni ukhetha iilensi ezitshintsha umbala?
Ngokunyuka kwamazinga e-myopia, kukho imfuno ekhulayo yeelensi ezitshintsha umbala, ngakumbi entwasahlobo nasehlotyeni, xa ilanga likhanya ngokuqaqambileyo kwaye imitha ye-UV inamandla, inokuba yingozi emehlweni.
Ke ngoko, eyona ndlela ilungileyo yokukhusela amehlo akho kwimitha ye-UV ngelixa ujongana neengxaki ze-refractive kukunxiba iiglasi eziguqula umbala kunye nokhuseleko lwe-UV (iperi yeglasi etshintsha umbala kunye ne-diopter).
I-05, izibonelelo zeelensi zokutshintsha umbala
Isipili esineenjongo ezininzi, kunqanda ukukhetha kunye nokunxiba ingxaki
Abantu abangaboni ngasonye kufuneka banxibe iperi yezibuko zelanga ukuba bafuna ukuthintela imitha yelanga ye<em>ultraviolet emva kokuba beye balungiswa amehlo abo ngokuwakhupha.
Iilensi ezitshintsha umbala ziiglasi zelanga ezine-diopter.Ukuba uneelensi ezitshintsha umbala, akufuneki ube neepere ezimbini zeeglasi xa uphuma.
I-shading enamandla, ivimbela umonakalo we-UV
Iiglasi ezitshintsha umbala zinokutshintsha ngokuzenzekelayo umbala ngokuhambelana nokukhanya kunye nobushushu, kwaye ulungelelanise ukuhanjiswa nge-lens yokutshintsha umbala, ukuze iliso lomntu likwazi ukulungelelanisa nokutshintsha kokukhanya kwendalo.
Ukongezelela, iyakwazi ukufunxa imisebe ye-ultraviolet eyingozi emehlweni abantu, ithintele i-glare kunye nomonakalo owenziwe yimisebe ye-ultraviolet, ukunciphisa ngokufanelekileyo ukukhanya kokukhanya, ukuphucula induduzo ebonakalayo, ukunciphisa ukukhathala okubonakalayo, ukukhusela amehlo.
Ukwandisa umhlobiso, omhle kunye nendalo
Iilensi ezitshintsha umbala zifanelekile kwindawo yangaphakathi, yokuhamba, nangaphandle.Ayizizo izibuko zelanga kuphela ezithintela ilanga, kodwa kunye ne-myopia / lens zokujonga kude ezinokulungisa umbono.
Ifanelekile kuyilo olwahlukeneyo lwelensi, inkangeleko enesitayile, ukuhlangabezana nokusukela ifashoni ethe kratya, ukuhlanganiswa kunye nokusebenza zombini.
