SportRx Frame Width™

136mm

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.

DETERMINING 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.

Adjustable

An 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.

The Zeal Optics Westwater sunglasses are built for those who push limits on water, trails, and peaks. Inspired by Utah’s rugged Westwater Canyon, these performance-driven shades feature an 8-base wraparound design for maximum coverage and protection. The Z-Resin bio-plastic frame is lightweight yet durable, perfect for fishing, mountain biking, running, or mountaineering. Rubber nose pads and bent rubber temples ensure a secure, no-slip fit during high-intensity adventures. Slide-on ventilated side panels block glare while maintaining airflow for clear, fog-free vision. Designed for a large fit, the Westwater sunglasses include a hard case and microfiber bag to keep them protected. Available in prescription at SportRx, these shades offer uncompromising clarity for those who never slow down.

Benefits

Clarity, Color, Contrast

These plant-based polarized lenses boost color and contrast, filter blue light, and protect from UV all while remaining environmentally friendly.

Eco-Friendly

Z-Resin is a durable plant-based frame material derived from the castor plant. Lighter weight and more comfortable for everyday wear and activities.

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.

Peripheral Protection

Wind, dust, and debris are no match for side shields. Keep your eyes comfortable and your vision clear with extra side shield protection.

Sweat Management

Unique frame design allows for increased airflow which wicks away and drains any sweat or moisture you work up.
