Refractometer siv kev txawj ntse, Kuv ntseeg tias ntau tus neeg tsis paub
01 computer optometry nta
Lub degree ntawm astigmatism thiab axial yog ntau dua
Qhov tshwm sim ntawm pob yog cuam tshuam los ntawm kev hloov kho ntawm qhov raug loj dua kuj yog qhov yuam kev me ntsis yog qhov qub.
Thaum lub khoos phis tawj optometry, Refractometer tus kws tshuaj xyuas yuav tsum ua tib zoo mloog cov lus qhia, xws li: "Tam sim no koj pom ib lub tsev nyob ntawm txoj kev kawg, thov ua tib zoo ntsia lub tsev kom pom, tsis txhob saib ntawm txoj kev, xav txog lub tsev. kawg ntawm lub tsev kawg." Qhov no yuav cia cov neeg mob Kho kom ntau li ntau tau los so kom txaus. (Peb tau sim, yog tias tshwj xeeb rau tus neeg mob saib ntawm txoj kev nyob ze kom pom, cov txiaj ntsig optometry feem ntau dhau kev kho!) Yog tias koj tsis xyuam xim rau cov lus tsim nyog los coj cov neeg mob, feem ntau tshwm sim los ntawm kev kho myopia.
02 computer optometry nyob rau hauv cov txheej txheem ntawm kev mloog
3 npaug ntawm cov txiaj ntsig ntawm lub computer optometry spectrophotometric qhov sib txawv ntawm 50 degrees lossis ntau dua, Refractometer qhia tias cov neeg mob yuav muaj teeb meem kev hloov kho hauv qhov pom kev ua haujlwm tuaj yeem hloov kho thaum lub hom phiaj ntawm kev hloov kho ntawm kev tshuaj xyuas.
Yog tias lub khoos phis tawj optometry pom astigmatism degree thiab axial instability, kev hloov pauv yog qhov loj, mus rau cov tshuaj thaum lub koob yees duab yuav tsum tau them sai sai rau txo tus nqi ntawm astigmatism los hloov lub zog sib npaug.
Ua tib zoo saib xyuas qhov kev hloov pauv ntawm cov menyuam kawm ntawv ntawm txhua tus neeg mob thaum ntsuas kev hloov pauv, Refractometer yog tus menyuam kawm ntawv nyob rau hauv cov txheej txheem ntawm kev hloov sai sai, qhia tias qhov kev hloov pauv hloov tau zoo (ntau dua hauv cov menyuam yaus lossis cov hluas); ntawm qhov tod tes, yog tias tus menyuam kawm ntawv hloov pauv hauv cov txheej txheem qeeb, qhov ntawd yuav hloov tau yooj yim, lossis hloov kho me ntsis, hloov kho tsis zoo. Hauv qab ntawm qhov pom kev ua haujlwm tuaj yeem tsom mus rau kev tshuaj xyuas.
Ua ke nrog cov txiaj ntsig ntawm kev kuaj pom pom pom: Yog tias qhov tsis pom kev tsis pom zoo tsis yog qhov tsis zoo, xws li 0.5, tab sis lub khoos phis tawj optometry tau tshwm sim rau -1.00D (tshwj xeeb muaj feem xyuam high degree), qhia tau hais tias tej zaum yuav muaj kev tswj ntawm spasm, pseudo-myopic teeb meem tshwm sim.
Thaum tus neeg mob ntsia ntawm lub khoos phis tawj optometry (tsev) pom, Refractometer yog lub cornea center reflex point tsis nyob hauv qhov chaw, qhia tias lub kaum sab xis ntawm lub kappa yog qhov loj, hauv daim iav gradient kom xyuam xim rau lub kaum sab xis loj. interpupillary nrug ntsuas yuam kev The
