1. Loluphi uhlobo lwemathiriyeli yelensi ekhoyo?
Izinto zendalo: ilitye lekristale, ubunzima obuphezulu, akulula ukusila, inokuhambisa imisebe ye-ultraviolet, kwaye ine-birefringence.
Izinto ezenziweyo: kubandakanya iglasi ye-inorganic, iglasi ye-organic kunye ne-optical resin.
Iglasi ye-inorganic: Inyibilikiswa kwi-silica, i-calcium, i-aluminiyam, i-sodium, i-potassium, njl., kunye nokucaca kakuhle.
I-Plexiglass: Ukwakhiwa kweekhemikhali yi-polymethyl methacrylate.
I-resin ye-Optical: Ukwakhiwa kweekhemikhali yipropylene diethylene glycol carbonate. Iingenelo bubunzima obulula, ukuxhathisa impembelelo, ukubumba ukubunjwa, kunye nokudaya lula.
2. Ziziphi iingenelo kunye nokungalunganga kweelensi ze-resin?
Izinto eziluncedo: ubunzima obulula, abubuthathaka, akukho miphetho okanye iikona xa ziphukile, zikhuselekile
Izinto ezingeloncedo: iilensi ezinganxitywayo zijiyile kwaye ixabiso liphezulu kancinci
3. Yintoni i-bifocal lens?
I-lens efanayo inokukhanya okubini, ukukhanya okuphezulu yindawo ekude, kwaye ukukhanya okuphantsi yindawo ekufutshane.
4. Ziziphi iimpawu zeelensi ezininzi?
Iperi yeglasi inokubona kude, phakathi kunye nemigama emifutshane, ingenamthungo, intle, kubantu abancinci ukulawula i-myopia, izigulane ezineminyaka ephakathi kunye nezalupheleyo ezine-presbyopia zingenza ubomi bube lula.
5. Yintoni i-lens eqinile?
Ukuqina, njengoko igama libonisa, kuthetha ukuba i-lens inzima kuneelensi eziqhelekileyo. Iilensi eziqinisiweyo ziyakwazi ukumelana nokunxiba. Umgaqo-siseko kukuba umphezulu we-lens uhlanganiswe ngamasuntswana akhethekileyo e-ultra-fine aqina unyango ukuze kuphuculwe ukuxhatshazwa kwe-lens kunye nokwandisa ubomi benkonzo. .
