SportRx Frame Width™

137mm

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.

Benefits

Beyond Polarized

In addition to fighting glare, Costa 580 polarized lenses filter out harsh yellow light & absorb bad HEV blue light. Experience higher definition, sharper contrast, & enhanced color.

Here to Stay

Never worry about your sunglasses falling off again. Costa’s Hydrolite material will absorb your sweat, keeping them secure and comfortable all day long.

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.

Stay Cool

Ventilation built into the frame allows for increased airflow. This helps reduce the lens from fogging and keeps you cool even on the hottest days.
