This new style in an aviator bifocal is a great new addition to our line. It is very much like our best-selling aviator (6000A), but it is just a bit smaller. It is UVA/UVB protected and is a great buy for the price. It comes in three choices of metal frame: silver, gunmetal, and muted tortoise. Frame Front Measurements: 5 1/2" x 1 5/8"
