M Frame lenses have come in many shapes over the years. While some passed quickly, others have remained unchanged for over a decade and a half.

Oakley first introduced the Mumbo with the 67, V and Hybrid lenses. In 1991, this was expanded to some of the shapes that are more familiar today. The Strip was added, but not for long. Sweep and Heater joined the lineup and Strike and Slash were promised to be coming soon.

Two years later the lenses were boiled down to the four that we see today. Slash was still around, but was unique and more than just a different lens. Strike, Sweep, Heater and Hybrid became the lineup that still exist today, and even into the Radars although under different names. By 1996, the frames changed to the Elliptical Icon, but the lenses remained the same until a few years later when the Hybrid, which was a 'hybrid' of the 67 and V both not existing for six years, became a hybrid of Heater and Strike and thus relabeled New Hybrid. The Pro M Frame, molded from a more curved model, was also released and while possessing the new and old hybrid lenses, formed the basis for the New M Frame. In 1999 a smaller version of the New Hybrid was created labeled the Hybrid S.

When the Radars came out, the lenses needed to be contoured to fit the frame. While the outside edges were essentially the same, using the same names would infer that they could be swapped. Before they were released, they did use the old naming convention. Once the new names were finalized Heater become Range however the SKU's for Strike and New Hybrid were assigned to Path and Pitch respectively despite Path being the translation of Hybrid and Pitch being like Strike. This happened before commercial release so it remains little more than a footnote.

Further additions to the Radar lineup included the female-specific Edge lens borrowed from the Endure frame, and the Blades lens which was the sole option for the XL frame. Upon the release of the RadarLock, all lenses except for the Range were available. Due to the Switchlock technology, the lenses were not backwards compatible. The Radar EV, which was also incompatible, only retained the Path and Pitch.

In addition to the Radar, several new M Frame successors appeared. The SI Ballistic M Frame 2.0 and 3.0 both used the older New Hybrid and Strike lenses, but labeled as 'Aggro' variants. They had a hole drilled into the nose bridge where a clip was used to hold them in place. Outside of SI, the M2 was released and would physically hold the older M Frame lenses, but came with its own shape and was not designed to be backwards compatible. Finally the M Frame Alpha introduced another new lens shape with its own locking technology, and was compatible only with the Halo Goggle as part of the Alpha Eco-system.
