If you’re looking for a striking style to balance round features, you’ll love the Mainstay FNDTN008. This fresh frame boasts a bold rectangular design with a straight browline that is great for tall brows. These specs will suit medium to large faces. Note: due to frame thickness, this style only accommodates prescriptions from -4.00 to +2.50.
