SportRx Frame Width™
126mm
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.

*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.
Wiley X Fierce sports glasses are your kid’s best bet to safety and optimal vision on the field. That's why they were nominated for the Best Kid's Sport Glasses of 2018 at the SportRx REXY's. Built with polycarbonate, shatter-resistant lenses and high-impact frames, Wiley X Fierce kids sports glasses are extremely durable. The Wiley X Fierce features a low-profile frame with straight-back, slim temples for a comfortable fit under a helmet. Wiley X Fierce doubles as sports glasses and sports goggles with a removable elastic strap. Need prescription sports glasses? Our opticians will gladly custom-build your Wiley X Fierce prescription sports glasses.
Benefits

Secure Comfort
Rubber temples aid a secure and steady grip so your sunglasses can rest comfortably on your head.
Sweat Management

Superior Retention
