Kev txhim kho keeb kwm ntawm optometry tshuab

Txij li thaum nrhiav tau ntawm Sterner txoj cai nyob rau hauv 1619, nws tau raug siv rau ntau yam tsis siv neeg optometers rau hnub no. Tom qab xyoo 1759, lub tshuab kho qhov muag pom tau tshwm sim, thiab nws tsis yog txog thaum xyoo pua 20th uas lub hom phiaj tsis siv neeg optometry tshuab tau qhia. Tab sis hom refractometer no yuav tsum tau kho lub hom phiaj projection cheeb tsam kom raug, thiab tsis tuaj yeem so kom txaus thiab kho. Cov txiaj ntsig tshuaj xyuas tsis raug txaus, yog li nws tsis tau nthuav dav dav.
Nrog rau kev txhim kho cov khoos phis tawj hluav taws xob, kuj tseem muaj kev txhim kho tshiab hauv lub hom phiaj optometry. Txij li xyoo 1969, cov optometers tsis siv neeg tau siv lub teeb infrared ua lub teeb ci thiab hluav taws xob automation systems los kho cov qauv kev pom. Qhov tseeb tuaj yeem ncav cuag 0.12-0.25D, thiab cov cuab yeej siv tshuab yog hloov tau thiab zoo heev, nrog rau ntau yam haujlwm. Nws yog txawm peem rau nrog ntau yam kev pom acuity kab kos thiab kho cov cuab yeej, thiab muaj nuj nqi ntawm kev ntsuas deviation thiab lub tso suab tsis pom kev.
Nyob rau hauv xyoo tas los no, cov haujlwm ntawm cov refractometers tshiab tau dhau los ua qhov zoo tshaj plaws. Lawv tsis tsuas yog muaj cov kev ntsuam xyuas kev ua haujlwm, tab sis kuj tuaj yeem tshawb xyuas thiab kho cov haujlwm, nrog cov txiaj ntsig raug. Lawv yog ib hom tshiab ntawm kev tsom xam binocular refractive analyzer. Ntau hom tsis siv neeg refractors tau tshwm sim, suav nrog hom kev kawm thiab hom phiaj. Qhov kev tshaj lij tshaj plaws yog kev siv lub teeb ci infrared thiab cov khoom siv hluav taws xob hauv computer ua ke nrog cov refractors tsis siv neeg, tseem hu ua computer refractors. Txoj kev ua haujlwm yog qhov yooj yim, thiab cov txiaj ntsig optometry luam tawm ntawm daim ntawv kaw tuaj yeem tau txais hauv vib nas this. Txawm li cas los xij, cov khoom siv kuj tseem kim, thiab cov neeg mob kev koom tes tsis zoo, uas tuaj yeem ua rau muaj kev ua yuam kev yooj yim.
