Smart glasses are quickly becoming one of tech’s busiest categories, but not every brand is chasing the same goal.
While products like Ray-Ban Meta Smart Glasses and the Oakley Meta Vanguard lean into cameras, AI and social sharing, French specialist Engo has been taking a more focused approach.
Its new Engo3 glasses are designed specifically for runners, prioritising real-time performance data over lifestyle features.
There’s no camera, no audio and no notifications, just a lightweight AR display that places key metrics directly in your field of vision.
The system projects information roughly three metres ahead using Engo’s ActiveLook light AR technology, allowing athletes to track stats without looking down at their running watch.
Core metrics include heart rate, pace, cadence and distance, with support for more than 40 data points depending on the setup.
Hardware built for training
The Engo3 weighs 38.5g and uses a wide-lens mask design with impact-resistant panoramic lenses, bringing it closer to a pair of performance sunglasses than a traditional wearable.
The frame includes adjustable temples and a configurable nose bridge to improve stability during movement.
A high-brightness OLED display, rated at over 3,000 nits, is said to ensure visibility in both direct sunlight and low-light conditions.
The MultiColor (RYG) projection system provides clearer visual differentiation among metrics, while optional photochromic lenses automatically adapt to changing light conditions.
Battery life is rated at up to 20 hours per charge, a notable increase over previous generations and enough to cover extended training sessions or endurance events.
Navigation is handled via a double-tap sensor built into the frame, with Bluetooth Smart (BLE) connectivity linking the glasses to smartphones and compatible devices.
Smarter software and integration
ENGO has also introduced a redesigned companion app, which plays a central role in the experience.
The platform allows users to customise data fields through widget-based layouts, tailoring the display to different types of runs, from steady efforts to interval sessions.
The glasses sync with major ecosystems, including Garmin watches and the Apple Watch, to pull in activity data and enable real-time feedback.
The launch of Engo3 underlines a growing divide in the growing smart glasses category.
While brands such as Meta continue to add cameras and connected features, Engo is focusing on a more specialised use case that benefits runners and other athletes.
The Engo3 is now available at Engo UK, Engo US and Engo EU, priced at £300 / $400 / €350 (~AU$587) for the standard version and £350 / $450 / €400 (~AU$670) for the photochromic model.
