Asymptotic multifocal glasses are the upper optical area of the lens used for far vision and the lower optical area used for near vision. The degree of the middle gradually changes, which is used for viewing the intermediate range. Most people who wear progressive multifocal glasses need about a week of adaptation, but the adaptation time varies from person to person; they go slower when they feel dizzy. When you go down, please lower your glasses and use the upper area. You will feel safe and comfortable.
