PRODUCT OVERVIEW
SportRx Frame Width™ (SFW) is the measurement our Sports Opticians use to find the most accurate fit possible. Unlike most eyewear measurements that have little to do with fit, SFW serves as an indicator for how well a frame or goggle will fit your face.

SportRx Frame WidthTM (SFW) is the measurement our Sports Opticians use to find the most accurate fit possible. Unlike most eyewear measurements that have little to do with fit, SFW serves as an indicator for how well a frame or goggle will fit your face.
DETERMINING YOUR SFW
Use Eyeglasses and Not SunglassesUsing flatter eyeglasses makes for a more accurate measurement. It takes a bit more finesse with wrapped sunglasses to get an accurate SFW measurement.
Make sure the glasses fit!Since we're using your glasses as a template for ideal fit, make sure they're a pair that are comfortable: not too wide, not too narrow. A quick glance in the mirror will show if the frames spread too far past the edges of your face or seem to 'pinch' it.
Have more than one pair?It never hurts to have more than one 'frame' of reference! If you have more than one pair that you love, you can measure multiple pairs and get an average.
How/What do I measure?Measure with the temples opened out fully. Aim for right behind the hinge and measure from the inside of the frame material of one side to the inside of the other side.

The RB3548N Hexagonal Flat is a modern update to the classic round silhouette we know and love from Ray-Ban. This fresh geometric shape makes a subtle statement that accentuates your individuality and enhances your unique style. Composed of a thin metal frame, the beauty is in the details. An etched pattern is featured on the refined saddle bridge, around the lenses, and along the temples. The flat crystal lenses not only enhance the clean design, but also offer 100% UV protection and optical clarity. Need your Ray-Ban sunglasses with prescription?
