Design: Seemingly Simple Sunglasses

 This Smart AR Glasseslooks almost identical to the XReal One, and can easily be mistaken for a slightly chunky pair of black sunglasses. A thin, glossy black front frame holds two smoke-tinted outward-facing lenses that can lighten or dim depending on whether you need to keep an eye on the real world around you or you want more isolation and higher contrast while viewing media. The lens-dimming feature carries over from the One , and is a nice perk that means you don’t have to deal with a snap-on sunshade or be committed to clear or dark lenses at all times.

Somewhat thick black temples extend from chrome-colored spring hinges and house the One Pro’s physical controls and most of its hardware. Each temple widens out to a slight bulge holding speaker grilles before narrowing into curved ear hooks, of which the left hook features a USB-C port for connecting the glasses. A brightness rocker and menu button sit on the underside of the right temple, with a shortcut button sitting on the top, opposite the menu button.
