So you’ve got an Oakley M Frame

Awesome choice! It’s an athletic frame style with a variety of lenses that allow for customization. So much variety, in fact, that it can be a bit overwhelming and sometimes downright confusing. Not to worry, I’ll break it all down for you.

Let’s start off with one of the most popular questions our Customer Experience receives:

What M Frame do I have?

Nine times out of ten, people own the most recent generation of M Frames that Oakley started producing in 1999. When they ask “What M Frame do I have” what they really mean is “What lenses are in my M Frame?

But, just to be sure, check out this blog post to verify which generation of M Frames you have. If you came here searching for information on the M2, go to this blog post instead.

Ok, I checked it out and I’m sure I have the M Frame Sweep.

Well, my friend, I’m about to blow your mind. If you’ve got the “M Frame Sweep” — what you’ve actually got is an M Frame with a Sweep lens installed.

You could also install a Heater, Hybrid, or Strike and they’d all fit. There’s no difference between the M Frames themselves, just the style of the lens that’s in them — and all of those lenses are interchangeable in your M Frame. Your options just quintupled, you’re welcome!

I get it. I’ve got M Frames and I’m ready to choose my lens.

Awesome, there’s a bunch of options so let’s take a look at what’s out there.

Heater

This lens style provides the most coverage out of all the Oakley M Frame lenses. The lower edges have large wings and the lens has a curvy and fluid shape.

Oakley M Frame Lens Comparison versus Various Styles

Sweep Vented (Revant Exclusive)

Oakley offers vented options for each of their M Frame lenses, but based off user feedback, the vents were letting in too much air and light into the wearer’s eyes. The lens we created to solve for this is in the Sweep style, and features custom vents at the top to maximize airflow without inhibiting the lenses ability to keep wind and debris out of your eyes.
