Kev ua tsov rog txawv teb chaws tseem txuas ntxiv mus, tab sis kev lag luam hauv tsev tseem txuas ntxiv qhia cov cai zoo, thiab ntawm sab kev lag luam, cov nqi hlau tau nce siab tshiab ntau zaus. Bifocals tau nce vim muaj kev thov ntau ntxiv thaum lub caij cua sov, kev txhawb nqa tus nqi tau muaj zog, thiab cov nqi hlau tau txuas ntxiv nce. , kev ntshai ntawm kev thov siab kawg tau nce ntxiv, kev ua haujlwm rov ua dua tshiab hauv kev ua lag luam tau nce ntxiv, kev tsim cov hlau nyoos txhua hnub tau poob qis, kev xa khoom hlau tau txo qis, ib qho kev sib tw av ntxiv tau pib, thiab kev ua lag luam qhov chaw ruaj khov thiab muaj zog. Los ntawm kev pom dav dav, cov nqi hlau yuav tsum ruaj khov thiab muaj zog tag kis.
