Nyob zoo cov phooj ywg, thaum koj xaiv tsom iav, koj puas xav paub ntau npaum li cas xaiv cov khoom ntawm lub lens?
Hnub no kuv qhia koj ib txoj kev paub tshiab
Qhov tseeb, nws tsis yog qhov nyuaj rau xaiv cov iav zoo.Ua ntej tshaj plaws, peb yuav tsum xav txog cov khoom siv ntawm cov iav.Cov khoom sib txawv muaj qhov sib txawv.
Nov yog qee cov khoom siv tsom iav tshaj plaws:
① iav (hnyav / fragile / hnav-resistant)
Cov iav lo ntsiab muag yog tus cwj pwm los ntawm qhov pom tseeb thiab siab hardness.Qhov tsis zoo yog tias lawv yooj yim tawg thiab hnyav heev.Tam sim no peb feem ntau tsis pom zoo yuav cov lens zoo li no.
②CR39 lo ntsiab muag (sib dua / tsawg dua / hnav-resistant)
Resin lo ntsiab muag yog tam sim no siv ntau tshaj plaws thiab yog cov ntaub ntawv zoo.Qhov zoo dua yog tias nws yog lub teeb, cuam tshuam-resistant, thiab tsis yooj yim tawg.Nyob rau tib lub sijhawm, nws absorbs ultraviolet rays zoo dua li cov iav lo ntsiab muag, thiab tuaj yeem ntxiv cov khoom tiv thaiv ultraviolet.
③PC (lub teeb heev / tsis nkig / tsis hnav-resistant)
PC lo ntsiab muag yog polycarbonate, uas yog cov khoom siv thermoplastic.Qhov zoo dua yog tias nws sib dua thiab nyab xeeb dua.Nws yog tsim rau rimless iav.Nws yog feem ntau haum rau kev tsim cov looj tsom iav dub, uas yog, cov looj tsom iav dub ntawm cov iav tiaj tus.
④Natural lo ntsiab muag (nyuaj thiab hnav-resistant)
