What to Look For in Oakley Sunglasses

There are plenty of features to consider when buying a pair of Oakley sunglasses. First, choose what you want to use them for: lifestyle, sport, or maybe a bit of both. After that, it comes down to the PRIZM lens options and frame colorway. But perhaps the most important consideration is fit.

If your sunglasses don’t fit correctly, you won’t look or feel your best — not to mention they will cause headaches or fall off your face. We created this Oakley size comparison to help you find the right pair that fits your face.


How Can I Determine The Size of my Oakleys?

On the inside of the temple arm you will find the eye size — more commonly known as lens width. This number is followed by the Oakley icon and a second number, which is the bridge width. The third number (following the bridge width) is the temple length.

For example, the number on a pair of Oakley Frogskins may read: 55 O 17 133. This translates to a lens width of 55mm, bridge of 17mm, and temple length of 133mm.

In the case of the Frogskins, there is a number in front of the eye size: 24-306. This is the part/SKU# that is unique to the specific frame and lens colorway. This number has nothing to do with frame size, but may help identify your sunglasses.

What Does XL mean in Oakley Sunglasses?

XL designates a frame in a larger size. It is common for Oakley to introduce a model and then create a larger XL version of the same frame. These have a wider frame as well as larger lenses.

All Oakley XL sunglasses cater to larger heads. Check out our list of the best Oakley Sunglasses for BIG Heads if you are specifically looking for large sunglasses.

What Does XS mean in Oakley Sunglasses?

XS denotes a smaller frame size. For example, Oakley Frogskins are also available in a smaller size as Oakley Frogskins XS.

These frames are perfect for kids or adults with small faces. For a full list of our favorite Oakleys for faces on the smaller side, read Best Oakley Sunglasses for Small Faces.

What is Oakley Standard Fit?

Standard fit is the basic/classic sizing identification Oakley sunglasses are known for. This designation provides a reference point between standard fit and Asian Fit.

What is Oakley Asian Fit?

Oakley Asian Fit sunglasses are designed for the face shape and structure of someone with a flatter face and/or higher cheekbones. These sunglasses have thicker nose pads that help lift the sunglasses off the face and compensate for a flatter nose bridge.

In the case of the Flak 2.0, the frame chassis is even wider and flatter than the standard fit version. Many half-rim Asian Fit sport frame lenses are also cut flat on the bottom for avoiding contact with the face.
