Asymptotic multifocal glasses have the upper optical area of the lens used for far vision and the lower optical area used for near vision. The power in the middle gradually changes, which is used for viewing the intermediate range. Most people who wear progressive multifocal glasses need about a week to adjust, but the adjustment period varies from person to person; they will go slower when they feel dizzy. When going down stairs, lower the glasses and use the upper area. You will feel safe and comfortable. Package Includes: 1 * Reading Glasses
