These Mainstay FNDTN001 D-frame glasses are modern and stylish. This flexible frame is lightweight and agile, making them the perfect choice for everyday wear - no matter what life brings your way. The vintage keyhole bridge will sit comfortably on wider nose bridges. Note: due to frame thickness, this style only accommodates prescriptions from -4.00 to +2.50.
