Ulwazi lwamalensi ezingilazi

1. Yiziphi izinhlobo zezinto zamalensi ezikhona?

Izinto zemvelo: itshe lekristalu, ubulukhuni obuphezulu, akulula ukusigaya, lingadlulisela imisebe ye-ultraviolet, futhi line-birefringence.

Izinto zokwenziwa: kufaka phakathi ingilazi ye-inorganic, ingilazi ye-organic kanye ne-optical resin.

Ingilazi ye-Inorganic: Incibilikiswa ku-silica, i-calcium, i-aluminium, i-sodium, i-potassium, njll., ngokusobala okuhle.

I-Plexiglass: Ukwakheka kwamakhemikhali yi-polymethyl methacrylate.

I-Optical resin: Ukwakheka kwamakhemikhali yi-propylene diethylene glycol carbonate.Izinzuzo isisindo esilula, ukumelana nomthelela, ukubunjwa kokubunjwa, nokudaya kalula.

 

2. Yiziphi izinzuzo kanye nokubi amalensi resin?

Izinzuzo: isisindo esilula, asiyona intekenteke, ayikho imiphetho noma amakhona lapho ephukile, ephephile

Ukungalungi: amalensi angagqoki aminyene futhi intengo iphakeme kancane

 

3. Yini i-bifocal lens?

Ilensi efanayo inokukhanya okubili, ukukhanya okungaphezulu kuyindawo ekude, kanti ukukhanya okuphansi kuyindawo eseduze.

 

4. Yiziphi izici zamalensi amaningi?

Ipheya lezibuko liyakwazi ukubona amabanga akude, aphakathi nendawo namafushane, angenamthungo, amahle, ukuze abantu abasha balawule i-myopia, iziguli ezineminyaka ephakathi nesele asebekhulile abane-presbyopia zingenza ukuphila kube lula.

 

5. Iyini ilensi eqinile?

Ukuqina, njengoba negama liphakamisa, kusho ukuthi ilensi ilukhuni kunamalensi ajwayelekile.Amalensi aqinile anokumelana nokugqokwa okukhulu.Isimiso siwukuthi ubuso be-lens buhlanganiswe nezinhlayiya ezikhethekile ze-ultra-fine zokwelapha eziqinisayo ukuze kuthuthukiswe ukumelana nokuguga kwelensi nokwelula impilo yesevisi..
