Khoom nta
1) Qhov zoo ntawm 1.499
①Nws yog pheej yig, txij li nws tau nyob ib ncig ntawm 70 xyoo.Optically hais lus, nws muaj qhov zoo, tsim nyog du refractive nto, thiab me ntsis distortion ntawm cov npoo ntawm lub lens
②Qhov zoo ntawm CR39 lo ntsiab muag dhau lub iav lo ntsiab muag yav dhau los yog lub teeb yuag, thiab zoo dua tawg ua haujlwm.Qhov hnyav qis tso cai rau cov neeg tsim tsom iav los sim nrog cov lo ntsiab muag loj dua, vim CR39 yog qhov hnyav dua.
③Txawm hais tias CR39 muaj qhov cuam tshuam zoo dua li cov iav lo ntsiab muag, nws tseem tuaj yeem tawg raws li qhov cuam tshuam zoo.Vim li no, ntau thiab ntau cov kws kho qhov muag tau hloov mus rau cov khoom siv lens tshiab (polycarbonate thiab lwm yam, yuav tsum tau tham hauv cov ntawv yav tom ntej) uas yuav luag tsis tuaj yeem tawg.
④Far lighter dua lub iav lens
⑤A pov thawj zoo nyob rau hauv ntau yam
⑥ Muaj nyob rau hauv txhua tus qauv tsim thiab kev kho tus nqi ntxiv
⑦Rau txhua tus neeg hnav uas tab tom nrhiav qhov yooj yim, exonomical lens
2) Tshem tawm thiab ntxiv rau cov lo ntsiab muag semi-tiav
① Lens nrog lub zog dioptric sib txawv tuaj yeem tsim los ntawm ib lub lens semi-tiav.Qhov curvature ntawm sab pem hauv ntej thiab sab nraub qaum qhia tias lub lens yuav muaj lub zog ntxiv lossis rho tawm.
② Semi-tiav lo ntsiab muag yog cov khoom siv raw khoom siv los tsim lub lens RX tus kheej feem ntau raws li tus neeg mob cov tshuaj.Cov tshuaj muaj zog sib txawv thov rau ntau hom lens semi-tiav lossis lub hauv paus nkhaus.
③ Ntau dua li cov tshuaj pleev ib ce zoo xwb, cov lo ntsiab muag semi-tiav yog ntau ntxiv txog qhov zoo ntawm sab hauv, xws li qhov tseeb thiab ruaj khov, tshwj xeeb tshaj yog rau lub lens freeform.
3) Qhov txawv ntawm HC, HMC thiab SHC yog dab tsi?
| Txheej tawv | AR txheej / Hard txheej txheej | Super hydrophobic txheej |
| ua rau lub lens uncoated nyuaj thiab tsub kom lub abrasion kuj | tsub kom lub transmittance ntawm lub lens thiab txo cov reflections nto | ua rau lub lens waterproof, antistatic, anti plam thiab roj kuj |
