The glasses feature waveguide-based, see-through optics driven by a Cobra II DLP-based display that's projected onto the glass. This improved frame material features a new formula that is less prone to the cracking and brittleness of the Original Blades.

You often hear people talk about the Oakley Razor Blades and Blades, but at the end of the day, they’re all the same system. Today if you looked up a definition of the ’80s, you’d probably see the Oakley Blade, with its shield lens and bright colors.Rain beads up and runs off, and if the lens fogs up (sometimes I wear them on the back of my head when climbing, and they fog this way), they clear up quickly on their own. Followed by the Razor Blade, then ultimately the Slit lens offering the lowest profile lens (pictured below). They catapulted Oakley to global recognition, became an icon of the 1980s, and laid the groundwork for decades of Oakleys to come. The Blade and Razor Blade offered replaceable lenses, earstems, top brow plastic, and nose pieces in varying mix and match colors which let you create over 22 million different combinations of customization! This just boiled down to close to 20 years of continued innovation by Oakley in enhancing its products.

The Stretchline and later Re-releases (Collectors, Heritage Collection and Kith) had the same general design as the original. Much like the Swedish company’s standout helmets, the POC DO Half Blade sunglasses are hard to miss. Supporting all that is an 8-megapixel camera for image capture and sharing directly through the Blade interface.The voice response is as snappy as we’ve seen on other Alexa-integrated products, and brings a lot of important functionality to such a device. The first was a pretty standard earstem similar to what you’d find on most modern sunglasses with a straight-line design that curves around your ear.
