*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.
If it's good enough for a NASCAR legend, its good enough for your face.

SPY Happy™ Lenses
A visual experience that you can feel. See better and feel better with SPY Happy™ lenses, the only scientifically proven lens with therapeutic benefits, letting in the good rays that boost mood and alertness, and filters out bad rays that create noise and haziness.
See Better. Feel Better.
Rich ColorsSPY Happy™ lenses keep out harmful UV and short-wave blue light, while clearing the path for richer, brighter colors and sharper contrast and clarity.
Improved MoodThe sun gives off rays that are both good and bad for your health and well-being. SPY Happy™ lens technology filters out the "bad rays" that are made of UV and short-wave HEV blue light that lead to fatigue and eyestrain, while allowing in the "good rays" that are made up of long-wave blue light.
More Than ContrastBecause other color enhancing lenses only focus on filtering out the bad rays, they end up blocking the good rays along with it. SPY Happy™ lenses filter out the bad while amplifying the good, providing you with a boost in mood along with a boost in contrast.
