2. Lub lens semi tiav yog dab tsi?
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.
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. Dab tsi yog qhov tseem ceeb ntawm lub lens zoo semi-tiav rau RX ntau lawm?
① Tus nqi tsim nyog hauv lub zog raug thiab ruaj khov
② Tus nqi tsim nyog hauv cov tshuaj pleev ib ce zoo
③ High optical nta
④ Cov teebmeem tinting zoo thiab cov txheej txheem nyuaj / AR txheej tshwm sim
⑤Realize lub peev xwm ntau lawm
⑥ Kev xa khoom raws sijhawm
Tsis yog tsuas yog qhov zoo tshaj plaws, cov lo ntsiab muag semi-tiav yog tsom rau ntawm qhov zoo ntawm sab hauv, xws li qhov tseeb thiab ruaj khov, tshwj xeeb tshaj yog rau lub lens nrov dawb.
4. 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 |
