Ulwazi lweelensi zeglasi

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, abukho buthathaka, 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 okusezantsi kukufutshane.

4. Ziziphi iimpawu zeelensi ezininzi?

Iperi yeglasi inokubona imigama ekude, ephakathi kunye nemfutshane, 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 zinokunganyangeki kakhulu.Umgaqo-siseko kukuba umphezulu we-lens uhlanganiswe ngamasuntswana akhethekileyo e-ultra-fine aqina unyango ukuze kuphuculwe ukuxhatshazwa kwe-lens kunye nokwandisa ubomi benkonzo..
