SportRx Frame Width™
134mm
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.
FINDING YOUR BRIDGE FIT
Finding the right eyewear for your face means two things: the right frame size and the right bridge style. At SportRx, we have three different bridge styles:
Standard
A standard nose bridge is best for those with nose bridges that go higher than their pupils, or if you have more narrow cheekbones. Standard nose bridges are fixed and don’t include adjustable nose pads.
AdjustableAn adjustable nose bridge includes flexible nose pads that can be adjusted for a firm, yet comfortable hold. This style is best for those who prefer a more customizable fit.
Low-Bridge
The low-bridge fit is designed for those with narrow nose bridges or cheekbones higher than their nose bridge. Also called Asian Fit, this is a great choice if your frames tend to slide down or touch your cheeks.
Nike 8138 eyeglasses are ready to take on any adventure you see on the horizon. 8138 is designed with a metal top bar construction that's paired with ultra-lightweight, injected temples that are made from plant-based resin. It has adjustable, rubber nosepads and temple tips that add extra grip for stability. Finishing off with a partial core wire for easy adjustability and an optimal fit for all your adrenaline-seeking days the 8138 eyeglasses might just be the frames for you.
Benefits
Customized Comfort
Fine-tune the fit of your glasses with adjustable nose pads for better optical alignment, comfort and wear-ability.
Slip Free
Rubber nose pads keep your frames in place and optically aligned even as you sweat, jump, slide, bounce, you name it.
Secure Comfort
Rubber temples aid a secure and steady grip so your sunglasses can rest comfortably on your head.
Sweat Management
Unique frame design allows for increased airflow which wicks away and drains any sweat or moisture you work up.
Glare Protection
Enables better vision by reducing the amount of reflective light bouncing off your lenses.
Water Resistant
Hydrophobic coating helps sweat and water droplets run-off the surface of lenses. Great for rainy days or for sweaty workouts.
