1. Progressive multifocal lenses: Progressive multifocal lenses cater to various daily needs (such as conversations, computer use, and reading), eliminating the constant need for reading glasses. The standard pupil distance and precise magnification ensure comfortable wear without dizziness, effectively enhancing reading convenience. 2. These progressive multifocal lenses are divided into three zones: upper, middle, and lower. The upper zone has no diopter (0 diopter). The middle zone transitions from 0 diopter to your selected diopter (e.g., if you choose 1.0 diopter, the middle zone will be 0.5 diopter). The lower zone provides the full reading strength with your chosen diopter. 3.
