Sailors used to carry pocket telescopes. Birdwatchers still carry monoculars. Geologists carry hand lenses. What these instruments share, beyond the obvious optical function, is a deliberate relationship to information: you raise the tool when you choose to engage with it, and the world stays unmediated the rest of the time. That’s actually a pretty sophisticated UX philosophy, and it’s one the entire wearable tech industry has quietly abandoned in favor of always-on overlays, persistent notifications, and the assumption that more access to information is axiomatically better. Yuxuan Hua’s Lens concept is a Silver A’ Design Award winner that makes the counterargument in hardware form.
The concept is a detachable AR smartwatch that splits into two objects: a wrist-worn puck for everyday use and a handheld monocular for AR-enhanced outdoor exploration. The back face of the module houses a dual-lens optical array, a wide camera and LiDAR sensor tucked into a vertical pill recess, while the face doubles as a circular display that overlays navigation prompts, species identification, and star charts over a live feed when held up like a field scope. The band itself is Alpine-loop textile, the lug system simple enough to suggest the module can swap across band styles, and the whole thing comes in at 48mm wide and 68g. The rendering detail is strong: the detached module has the cold, machined look of a quality compass or a classic light meter, the kind of object that rewards handling.
Designer: Yuxuan Hua
Hua interviewed hikers, foragers, and stargazers and found three consistent frustrations: devices were too bulky and fragile for rugged environments, and frequent screen interactions broke the rhythm of being outside. The phone-as-field-guide pattern, pull it out, unlock, navigate to the app, wait for it to load, try to hold it steady while pointing at something, is a sequence of six interruptions where you actually wanted zero. Smart glasses solve the unlock problem but introduce the far more annoying problem of a permanent digital scrim between you and whatever you came outdoors to look at. The monocular is the thing you raise when you want to know something and lower when you don’t, which is precisely how attention works when you’re actually engaged with a landscape.
Most AR concept hardware reaches for science fiction: translucent surfaces, glowing elements, the visual grammar of a prop department. Lens reaches instead for the instrument drawer: the detached module has the proportions and material honesty of a quality compass housing or a Leica light meter, machined aluminum with visible fasteners and a lens array that looks like it belongs in an optician’s toolkit. It doesn’t look like the future. It looks like a very well-made tool, which is a significantly harder design target to hit.
Hua began developing Lens in 2021, during the pandemic, which is useful context. Lockdown-era design projects often reveal what designers actually miss about the physical world when it’s taken away, and what Lens mourns, obliquely, is uninterrupted attention. The whole concept is an argument that the best AR device for outdoor use is one that disappears when you’re not using it, one that earns its presence by staying out of the way until the moment it’s needed, then delivers exactly what the moment requires. Whether the engineering can catch up to that vision, packing AR projection, LiDAR, and a wide-FOV camera into a 68g coin of aluminum, is another question entirely. As a design proposition, it’s already done its job.
