The degree in the middle changes gradually, which is used to view the intermediate range. Most people who wear progressive multifocal glasses need about a week of adaptation, but the adaptation period varies from person to person; they go slower when they feel dizzy. When going down stairs, lower your glasses and use the upper area. You will feel safe and comfortable. nProduct Size: nTotal Width: 137mm (5.39 inches) nArc Width: 52mm (2.05 inches) nArc Height: 42mm (1.65 inches) nBridge Width: 16mm (0.63 inches) nTemple Length: 135mm (5.31 inches) nWeight: 21.6g (0.76oz) nPackage Contents: n1 x Reading Glasses nNote: n1.
