Kutheni iiLensi zePolycarbonate?

Ibhityile kwaye ikhaphukhaphu kuneplastiki, iilensi ze-polycarbonate (i-impact-resistant) zinobungqina bokuqhekeza kwaye zibonelela ngokhuseleko lwe-UV oluyi-100%, nto leyo ebenza babe lolona khetho lufanelekileyo kubantwana nakubantu abadala abasebenzayo. Zikwayilungele imimiselo eyomeleleyo kuba abongezi ubungqingqwa xa belungisa umbono, ukunciphisa nakuphi na ukugqwetheka.

Yintoni iiLensi zePhotochromic?

Iilensi zePhotochromic ziilensi eziguquguqukayo ezizilungelelanisa ngokwazo kwiimeko ezahlukeneyo zokukhanya. Xa ungaphakathi,iilensi zicacile kwaye xa zibekwe kukukhanya kwelanga, zonajikamnyama ngaphantsi komzuzu.

Ukutshintsha koMbala okrelekrele

Ubumnyama bombala emva kokutshintsha kweelensi ze-photochromic zigqitywe ngamandla okukhanya kwe-ultraviolet.

I-photochromic lens inokuqhelana nokutshintsha ukukhanya, ngoko amehlo akho akufuneki enze oku. Ukunxiba olu hlobo lwelensiintandonceda amehlo akho aphumle kancinane.

Zisebenza njani iiLensi zePhotochromic?

Kukho iibhiliyoni zeemolekyuli ezingabonakaliyo ngaphakathi kweelensi zephotochromic. Xa iilensi zingabonakali ekukhanyeni kwe-ultraviolet, ezi molekyuli zigcina isakhiwo sazo esiqhelekileyo kwaye iilensi zihlala zibonakala. Xa zibonakaliswe ekukhanyeni kwe-ultraviolet, isakhiwo se-molecular siqala ukutshintsha imilo. Oku kusabela kubangela ukuba iilensi zibe nombala ofanayo. Emva kokuba iilensi ziphumile elangeni, iimolekyuli zibuyela kwindlela yazo eqhelekileyo, kwaye iilensi ziphinda zibonakale.

Kutheni le nto kufuneka sinxibe iiLensi zePhotochromic?

Ziyakwazi ukulungelelaniswa kakhulu kwiimeko zokukhanya ezahlukeneyo kwiindawo zangaphakathi nangaphandle
Banika induduzo enkulu, kuba banciphisa amehlo kunye ne-glare yelanga.
Ziyafumaneka kwimimiselo emininzi.
Khusela amehlo kwimitha yelanga ye-UVA kunye ne-UVB eyingozi (ukunciphisa umngcipheko we-cataract kunye nokuwohloka kwe-macular ezinxulumene neminyaka).
Zikuvumela ukuba uyeke ukujija phakathi kweeglasi zakho ezicacileyo kunye neendondo zakho zelanga.
Zifumaneka ngemibala eyahlukeneyo ukuze zihambelane nazo zonke iimfuno.
