SportRx Frame Width™ 
136mm
136mmSportRx 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.

*All Sizes in MillimetersDETERMINING YOUR SFW
Use Eyeglasses and Not Sunglasses
Using flatter eyeglasses makes for a more accurate measurement. It takes a bit more finesse with wrapped sunglasses to get an accurate SFW measurement.
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.
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.
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.
Ray-Ban RB4340 Wayfarer Ease is an alternate to the iconic Original Wayfarer. Delivering the same unmistakable look, the Wayfarer Ease has all the stylistic features of the original, minus the pantoscopic tilt, the forward angle that gives an exaggerated tilted profile to the Original Wayfarer. The RB4340 Wayfarer Ease is the No Tilt version, which some may find more comfortable. This effortlessly cool frame serves an equally impactful look without compromising comfort. If you love the Wayfarer style, but aren’t loving the tilt, the Ray-Ban RB4340 Wayfarer Ease is your way to achieve iconic style with total ease.
