Nrog rau kev nce qib ntawm thev naus laus zis, cov khoom siv iav tsom iav tau dhau los ua ntau yam. MR-8 iav tsom iav, ua cov khoom siv iav tshiab zoo, tau txais kev nyiam ntawm cov neeg siv khoom. Tsab xov xwm no lub hom phiaj yog qhia txog cov yam ntxwv ntawm cov khoom siv ntawm MR-8 iav tsom iav thiab qhia txog qhov zoo ntawm 1.60 MR-8 tsom iav.
MR-8 yog cov khoom siv resin siab uas muaj cov yam ntxwv hauv qab no:
a. Nyias heev thiab tsis hnyav: Cov khoom siv MR-8 uas muaj cov ntsuas refractive siab ua rau cov iav nyias dua, ua rau lawv sib dua thiab xis hnav dua piv rau cov iav ib txwm muaj.
b. Pom tseeb heev: Cov iav MR-8 muaj cov yam ntxwv zoo heev, ua rau pom kev meej thiab pom kev kaj thaum txo qhov cuam tshuam ntawm lub lens.
c. Muaj zog tiv taus khawb: Cov iav MR-8 raug kho tshwj xeeb, ua kom lawv tiv taus khawb thiab ntev lawv lub neej.
d. Kev ruaj khov siab: Cov khoom siv MR-8 muaj lub zog zoo heev, ua rau nws tsis yooj yim hloov pauv thiab ua kom muaj kev ruaj khov ntev piv rau cov iav ib txwm muaj.
Tsim los ntawm cov yam ntxwv ntawm MR-8, 1.60 MR-8 tsom iav muab cov txiaj ntsig hauv qab no:
a. Nyias heev thiab tsis hnyav: Cov tsom iav MR-8 1.60 siv cov khoom MR-8 nrog lub ntsuas refractive ntawm 1.60, ua rau cov iav nyias dua uas ua rau zoo nkauj dua thiab txo qhov kev xav ntawm kev ntxhov siab rau ntawm lub ntsej muag.
b. Pom tseeb heev: 1.60 MR-8 tsom iav muab kev xa hluav taws xob zoo dua, ua rau lub teeb txaus mus txog qhov muag thiab tiv thaiv kev pom tsis meej thiab lub teeb ci ntsa iab.
c. Kev tiv thaiv khawb zoo dua: 1.60 MR-8 cov tsom iav siv cov txheej txheem tshwj xeeb, txhawb nqa lawv lub peev xwm los tiv thaiv khawb thiab ua kom ruaj khov mus sij hawm ntev.
d. Kev tiv thaiv qhov muag: 1.60 MR-8 tsom iav tiv thaiv tau cov teeb meem ultraviolet, tiv thaiv qhov muag ntawm kev puas tsuaj UV.
e. Txhim kho kev tiv thaiv kev sib txhuam: 1.60 MR-8 cov tsom iav qhov muag muaj zog heev thiab kev tiv thaiv kev sib txhuam, ua rau lawv tiv taus kev tawg thiab muab kev nyab xeeb thiab kev ntseeg siab ntxiv.
Xaus lus, cov khoom siv tsom iav MR-8 muaj qhov zoo ntawm qhov sib dua, pob tshab, thiab tiv taus khawb. 1.60 MR-8 tsom iav, ua raws li cov txiaj ntsig no, muab cov txiaj ntsig ntxiv xws li nyias heev, muab kev pom tseeb siab, tiv taus khawb zoo dua, tiv thaiv qhov muag, thiab tiv taus kev nias zoo dua. Yog li ntawd, kev xaiv 1.60 MR-8 tsom iav ua rau muaj kev pom kev zoo dua thiab xis nyob dua.
