Progressive multifocal glasses feature an upper optical zone for distance viewing and a lower optical zone for near viewing. The power gradually changes in the central area to support intermediate vision. Most wearers require approximately one week to adapt to these lenses, though adaptation time varies by individual. If dizziness occurs, move slowly. When walking downstairs, tilt your head down and look through the upper part of the lenses for improved safety and comfort.
