Frame size is determined by the three key measurements found inside the frame arm: lens width (from 31-60mm), bridge width (from 12-31mm), and arm length (from 115-155mm).
Lens height is essential for multifocal prescriptions, such as Progressives, which require a minimum measurement of 28-30mm. They are also recommended for Rx sunglasses.

The Mainstay FNDTN003 has a contemporary geek-chic aesthetic with its streamlined D-frame shape and straight browline. Perfect for round and oval faces with tall brows, the wider lenses and thin rim also provide a striking look for square faces with wide cheekbones. Note: due to frame thickness, this style only accommodates prescriptions from -4.00 to +2.50.
