Goggles yog ib hom iav uas tuaj yeem hloov qhov siv thiab spectrum ntawm lub teeb xa mus kom tsis txhob muaj kev puas tsuaj rau lub qhov muag los ntawm lub teeb hluav taws xob. Nws yog ib qho tseem ceeb uas yuav muaj qee qhov muaj zog glare lossis ultraviolet rays hauv peb lub neej, uas tuaj yeem ua rau muaj kev puas tsuaj loj rau tib neeg' lub qhov muag thiab ua rau muaj kab mob ntawm qhov muag. Rau cov phooj ywg tsav tsheb, nws yooj yim rau kev sib tsoo tsheb. Qhov tshwm sim ntawm cov tsom iav tuaj yeem daws qhov teeb meem no. Yog li dab tsi yog lub luag haujlwm ntawm tsom iav?
Lub luag haujlwm ntawm tsom iav
Lub luag haujlwm ntawm cov iav tsom iav yog tiv thaiv lub qhov muag thiab lub ntsej muag los ntawm cov hluav taws xob hluav taws xob xws li ultraviolet, infrared thiab microwave hluav taws xob, plua plav, pa luam yeeb, hlau thiab pob zeb khib nyiab, thiab tshuaj lom neeg kev puas tsuaj sputtering. Rau tus phooj ywg tsav tsheb:
1. Anti-glare
Thaum tsav tsheb tom qab daus, peb daim teb ntawm kev pom yog dawb. Peb nquag txiav txim siab tsis ncaj thaum tsav tsheb, thiab nws tseem ua rau peb tsav tsheb. Cov looj tsom iav dub tuaj yeem txo qhov pom kev zoo thiab cia peb muaj nrog lub zeem muag pom tseeb, yog tias muaj xwm txheej ceev, peb kuj tuaj yeem txiav txim siab raws sij hawm kom txo tau peb qhov kev poob, thiab yuav tsis ua rau peb tsis tsim nyog los ntawm qhov pom. Anti-glare muaj nuj nqi tuaj yeem zam teeb meem teeb pom kev zoo. Qhov tshwm sim tshwm sim.
2. Tsis txhob xav txog
Thaum peb tsav tsheb thaum hmo ntuj, peb feem ntau ntsib cov tsheb uas muaj kab teeb siab, yog li peb tsis muaj qhov pom zoo thaum tsav tsheb. Yog tias peb tsis muaj tsom iav, peb yuav yooj yim ua rau txoj kev yuam kev thaum tsav tsheb thaum hmo ntuj vim yog lub teeb siab ntawm lwm lub tsheb. Qhov kev txiav txim tau ua rau muaj kev sib tsoo ntau heev.
Cov khoom siv tsom iav
Thaum cov tsom iav tsom iav tau tsim, qee cov hlau oxides xws li hlau, pob zeb diamond, chromium, strontium, npib tsib xee, manganese, thiab qee lub ntiaj teb tsis tshua muaj hlau oxides xws li neodymium, tau ntxiv rau cov qauv kho qhov muag iav. Cov hlau oxides no tso cai rau lub iav kom xaiv cov khoom nqus hluav taws xob tsis zoo nyob rau hauv ib qho ntawm lub teeb. Piv txwv li, oxides ntawm cerium thiab hlau tuaj yeem nqus tau ntau ntawm ultraviolet rays. Kev siv lub iav lo ntsiab muag no tuaj yeem txo cov nqi ntawm qee qhov wavelengths dhau los ntawm lub lens thiab txo lossis tiv thaiv kev puas tsuaj rau lub qhov muag. Cov xim sib txawv ntawm cov lo ntsiab muag tiv thaiv tuaj yeem nqus lub teeb ntawm cov xim sib txawv. Cov iav zoo li no tau muab faib ua ob pawg, ib qho yog hom kev nqus, lwm yam yog hom kev xav, qhov qub yog siv ntau tshaj.
Lens nyoos films feem ntau yog puag ncig. Cov tsom iav peb xaiv yuav tsum yog cov khoom uas tau raug tshuaj xyuas los ntawm lub koom haum tshuaj xyuas cov khoom; qhov loj ntawm cov tsom iav yuav tsum haum rau tus neeg siv lub ntsej muag; lub lens yog hnav thiab ntxhib, thiab lub thav duab puas, uas yuav cuam tshuam rau qhov pom ntawm tus neeg hnav. Yuav tsum tau hloov lub sijhawm.
