What’s the difference between Oakley’s standard lenses and those labeled XLJ or XL?
First off, let’s clarify that standard vs XLJ vs XL is strictly about LENSES. Not frames.
This distinction is quite important.
Some frame models offer more than one size of lens, but the frame itself does not differ in size specifications. For example, if you purchased Oakley Flak Jacket XLJ sunglasses, what you have are Flak Jacket frames with XLJ lenses installed.
If the box only says “Flak Jacket,” then your sunglasses came installed with standard lenses.
The standard and XLJ lenses are interchangeable within a frame style.
Standard lenses are shorter (top to bottom) and feature a more rounded cut to the bottom of the lens.
XLJ lenses are longer and have a wave-like cut along the bottom. These lenses provide more coverage than the standard lenses.
XLJ lenses are available for Oakley Half Jacket and Flak Jacket.
Here is a breakdown in lens specs for each model:
XL lenses are similar to the XLJ in that they’re typically longer than the standard lenses. However, XLJ lenses and XL lenses are not the same lens and are not interchangeable, as they are for different frames.

To sum up, the difference between these lenses comes down to size and shape. So long as you match up the correct frame, either the standard or its longer cousin will fit.

*Radar and RadarLock are the exception on lenses fitting interchangeably between XL and standard. Due to the way the nose piece connects to the frame, XL lenses will only fit Radar XL and RadarLock XL. And the same goes with standard lenses — they won’t fit their XL counterpart.
