Yuav ua li cas xaiv cov lo ntsiab muag rau koj ob lub qhov muag
Ua ntej ntawm tag nrho cov, koj yuav tsum tau yuav cov lo ntsiab muag tsuas yog nrog kws kho mob cov tshuaj. Nws yog ib qho tseem ceeb uas yuav tsum tau hais meej tias cov tsom iav tsom rau kev kho kev tiv thaiv tsis haum. Lenses raug xaiv raws li lwm yam tsis, lawv raug kho kom raug refractive yuam kev. Thaum xaiv lo ntsiab muag, ntau qhov ntsuas yuav ua raws li cov lus qhia.
Refractive index lossis optical zog. Nws tau qhia hauv diopters thiab txiav txim siab lub zog refractive ntawm lub lens. Qhov taw qhia tuaj yeem yog ntxiv lossis rho tawm.
Radius ntawm curvature. Qhov no yog ib qho qhia txog qhov muag ntawm txhua tus neeg, nws nyob ntawm qhov loj ntawm lub qhov muag.
Khoom kab. Qhov kev ncua deb ntawm ntug mus rau ntug ntawm lub lens, qhia nyob rau hauv millimeters, yog ib txwm qhia nyob rau hauv cov tshuaj los ntawm kws kho mob.
Hloov lub sij hawm. Qhov no yog lub sijhawm siab tshaj plaws ntawm kev siv lo ntsiab muag, qhov ntau dhau ntawm qhov yuav ua rau lub qhov muag puas. Tej zaum yuav yog ib hnub, rau kev hloov pauv tsis tu ncua tom qab 7, 14, 28 lossis ntau hnub.
cov khoom siv lens. Hydrogen sawv daws muaj tus nqi qis ntawm oxygen permeability, yog li lawv tsuas yog tsim nyog rau hnav thaum nruab hnub. Qhov tsis zoo no yog them los ntawm cov kua dej siab, uas tshem tawm qhov khaus thiab khaus thaum hnav.
Silicone hydrogel lo ntsiab muag yog cov dej noo thiab ua pa, cov qauv tuaj yeem hnav tau ntev.
Nrov lus nug thiab lus teb
Peb tau tham nrog tus kws tshaj lij ophthalmologist Natalia Bosha cov cai rau kev xaiv thiab kev saib xyuas ntawm lo ntsiab muag.
