1.67 MR-7 Xiav Txiav HMC Optical lenses

Kev Piav Qhia Luv:

Raws li tus qauv ISO, cov tsom iav tiv thaiv teeb xiav uas thaiv tau ntau tshaj 20% yog pom zoo rau kev siv txhua hnub ntawm cov khoom siv LED digital xws li TV, khoos phis tawj, pads thiab xov tooj ntawm tes. Cov tsom iav tiv thaiv teeb xiav uas thaiv tau ntau tshaj 40% raws li tus qauv ISO yog pom zoo rau cov neeg uas saib lub vijtsam ntau tshaj 8 teev hauv ib hnub. Vim tias cov tsom iav tiv thaiv teeb xiav lim tau ib feem ntawm lub teeb xiav, daim duab yuav daj thaum saib cov khoom, nws raug pom zoo kom hnav ob khub tsom iav, ib khub tsom iav ib txwm rau kev siv txhua hnub, thiab ib khub tsom iav tiv thaiv teeb xiav uas thaiv tau ntau tshaj 40% rau kev siv cov khoom siv LED digital xws li khoos phis tawj. Cov tsom iav tiv thaiv teeb xiav tiaj tiaj (tsis muaj degree) yog nrov heev ntawm cov neeg siv uas tsis muaj myopic, tshwj xeeb tshaj yog rau kev hnav khoos phis tawj hauv chaw ua haujlwm, thiab maj mam dhau los ua zam.

Kev Taw Qhia Txog Kev Tsim Khoom

1. Kev nqus cov khoom siv: lub lens substrate ntxiv nrog cov yam ntxwv tiv thaiv lub teeb xiav kom nqus tau lub teeb xiav tsis zoo hauv lub neej, yog li ua tiav lub hom phiaj ntawm kev thaiv lub teeb xiav.

2, zaj duab xis reflection: txheej txheej ntawm lub lens, los ntawm zaj duab xis yuav ua rau muaj teeb meem xiav reflection, tiv thaiv lub teeb xiav.

3, kev nqus substrate + zaj duab xis reflection: cov thev naus laus zis no sib xyaw ua ke qhov zoo ntawm thawj ob lub thev naus laus zis, ob-pronged, ob-effect tiv thaiv. [3]

Raws li lub hauv paus ntsiab lus ntawm cov xim sib phim, xiav thiab daj yog cov xim sib phim. Txawm tias nws raug nqus los ntawm lub lens substrate lossis cuam tshuam los ntawm txheej zaj duab xis, ib feem ntawm lub teeb xiav raug thaiv, yog li xim keeb kwm yav dhau ntawm cov tsom iav tiv thaiv lub teeb xiav yuav daj. Qhov siab dua qhov sib piv thaiv, qhov tob dua xim keeb kwm yav dhau ntawm lub lens yuav. Qhov no yog lub hauv paus ntsiab lus ntawm lub cev ntawm cov tsom iav tiv thaiv lub teeb xiav.

Lub teeb xiav uas ua rau mob muaj zog heev, tuaj yeem nkag mus rau hauv lub lens mus rau retina, ua rau cov hlwb epithelial pigment ntawm retina puas tsuaj thiab tuag taus. Kev tuag ntawm cov hlwb rhiab rau lub teeb tuaj yeem ua rau pom kev tsis meej lossis txawm tias poob tag nrho, thiab qhov kev puas tsuaj no tsis rov qab tau. Lub teeb xiav kuj tseem tuaj yeem ua rau mob macular. Lub lens ntawm lub qhov muag tib neeg nqus ib feem ntawm lub teeb xiav thiab maj mam ua rau pos huab los ua cataracts. Feem ntau ntawm lub teeb xiav nkag mus rau hauv lub lens, tshwj xeeb tshaj yog lub lens ntshiab ntawm cov menyuam yaus, uas tsis tuaj yeem tiv taus lub teeb xiav zoo, uas yuav ua rau muaj mob macular thiab cataracts.

Kev thaiv lub teeb xiav ntev yog txoj hauv kev zoo tshaj plaws los txo qhov kev puas tsuaj, thiab kev siv cov tsom iav thaiv lub teeb xiav tuaj yeem daws qhov teeb meem no tau zoo.
