Yuav ua li cas tswj lub thickness thiab qhov hnyav ntawm lub lens?
Lub thickness ntawm lub lens muaj feem xyuam rau qhov siab ntawm diopter, refractive index ntawm lub lens thiab cov duab thiab qhov loj ntawm lub thav duab, yog li thaum xaiv lub thickness ntawm lub lens, koj yuav tsum xa mus rau koj cov degree myopia. Yog hais tias qhov degree siab dua, xaiv qhov siab tshaj qhov ntsuas qhov ntsuas lub lens nyiam, yog li lub lens tuab yog nyias, tuaj yeem txo qhov siab ntawm tus choj ntawm lub qhov ntswg.
