Khoom nta
1) Qhov zoo ntawm 1.67 Index
① Lub teeb yuag thiab thinner thickness, mus txog 50% nyias thiab 35% sib dua li lwm yam lo ntsiab muag
②Nyob rau hauv qhov ntau ntxiv, lub lens aspherical yog li 20% sib dua thiab nyias dua li lub lens kheej kheej
③ Aspheric nto tsim rau qhov pom kev zoo
④ Flatter pem hauv ntej curvature dua non-aspheric lossis non-atoric lo ntsiab muag
⑤ Qhov muag tsis pom zoo dua li cov lo ntsiab muag ib txwm muaj
⑥ Kev ua haujlwm siab rau kev tawg (zoo heev rau kev ua kis las thiab menyuam yaus lub tsom iav)
⑦ Tag nrho tiv thaiv UV rays
⑧ Muaj nrog xiav txiav thiab photochromic lens
2) Lub ntsiab txhais ntawm semi tiav lens
① 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.
② Cov lo ntsiab muag semi-tiav yog tsim nyob rau hauv cov txheej txheem casting.Ntawm no, cov kua monomers yog thawj zaug rau hauv pwm.Ntau yam khoom raug ntxiv rau cov monomers, xws li cov pib thiab UV absorbers.Tus neeg pib ua rau muaj tshuaj lom neeg cov tshuaj tiv thaiv uas ua rau tawv tawv los yog "kho" ntawm lub lens, thaum lub UV absorber nce UV nqus ntawm lub lo ntsiab muag thiab tiv thaiv yellowing.
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 |
