1.56 Magirazi eHMC ane porgressive

Tsananguro pfupi:

Lenzi inofambira mberi igirazi rine urefu hwakawanda, rakasiyana nemagirazi ekuverenga echinyakare nemagirazi ekuverenga e-bifocal. Lenzi dzinofambira mberi hadzinetseki nemaziso ekuti dzinofanira kugara dzichigadzirisa urefu hwefocal padzinoshandisa urefu hwe-bifocal, uye hapana mutsetse uri pachena pakati pemutsetse wekuganhurira marefu maviri. Inonyaradza kupfeka uye ine chitarisiko chakanaka, uye zvishoma nezvishoma yave sarudzo yakanakisa kune vanhu vane presbyopia.
