engo2 Photochromic
All-conditions performance: light-adapting lens, instant metrics ahead, from sunrise to sunset.
Cat 1-3 photochromic lense. Auto-adjust from pre-dawn darkness to midday sun.
One system for all conditions—never swap glasses between sessions
Complete engo flow-state performance: 36g, 12-hour battery, 40+ metrics
"A game-changer for endurance athletes"
engo2's high definition Photochromic lens dynamically adapts to light conditions, transitioning from clear (Cat. 0) to dark (Cat. 3) based on external light.
engo2 is the lightest, smartest, highest performing heads-up display ever created for endurance athletes. It delivers an instant feedback on your performance, so you can adapt in real-time. Metrics from a compatible watch or cycling computer – heart rate, power, pace, distance and many more – keep you locked on pace for the entire session. Perfectly execute a training plan, and know exactly when to make your move on race day.
Any time of the day, any day of the year.
Compatible with Garmin, Apple Watch, iOs and Android.

We created the ENGO Care program to go beyond standard industry warranties. Crushed eyewear? Stolen bags? We've seen it all—and it's covered.
What's included?
They chose engo2
"115 miles a week, three custom screens — pace, lap data, heart rate. ENGO lets me focus on form and relaxation instead of checking my watch. Less stress, better effort management. I've never used a gadget that takes so little effort to deliver so much."
"2:28 PR, 110-mile weeks, engo2 is on my face for every single one. Pace, time, heart rate always in view. No looking down, ever. The photochromic lens took me from dark start lines to full sun at Houston. 7-minute PR. I never race without them."
"Pace, power, heart rate, all in my field of view. No looking down, just racing. At 65, I've set PRs at every distance. engo2 saved me minutes over the marathon. Worth every penny."
"I think it takes a little time getting used to the display ...now it's like second nature. One of things that I notice is it takes away the anxiety and stress of constantly checking your watch for stats and worrying about them."

See What You'll See
The ENGO display sits slightly left in your field of vision, like reading a road sign without turning your head. Available for your right eye, it's there instantly when you need data, invisible when you don't. Your brain naturally filters it out during focus, brings it forward on demand. Non-obtrusive by design.
ActiveLook Light AR technology
Delivers exactly what you need while in motion - nothing more, nothing less. High-efficiency MicroOLED display readable in any condition. 36 grams that outlast 12-hour training days.

Frequently Asked Questions
Will I even notice a difference?
Athletes report 5-8% reduction in perceived exertion and measurably better zone adherence. You'll feel it by your second workout. That's why we offer a 30-day trial—so you can prove it to yourself.
Is setup complicated? I'm not tech-savvy.
Apple Watch: Download ActiveLook app, pair your glasses, done. The ActiveLook companion app installs automatically on your watch. Start a run and your metrics appear.
Garmin: Download ActiveLook app, pair and setup your glasses, then add the ActiveLook datafield from Connect IQ to one of your activity screens. Launch your run and everything connects automatically.
Total time: 2-3 minutes. Easier than programming a new workout.
What if I don't like it?
30 days. Train with it. Race with it. If it doesn't transform your running, return it free. We take the risk so you don't have to.
I'm farsighted / wear prescription glasses. Will this work for me?
If you struggle to see your watch screen up close, this is where ENGO becomes a game-changer. The display projects 5-10 meters ahead—perfectly readable without squinting, tilting, or fumbling for reading glasses mid-run. For other vision corrections, contact lenses are required. Not sure? Try ENGO risk-free for 30 days.
Won't expensive glasses get scratched or broken in two weeks?
ENGO Care has you covered. For one year, if your glasses get scratched, broken, or stolen, we'll replace them. No worries, just training.
I have a Coros/Polar watch. Will it work?
ENGO is fully compatible with Garmin (all recent Forerunner, Fenix, Epix series) and Apple Watch (Series 4+). Suunto offers partial compatibility. Coros and Polar would need to develop support on their end—let them know you want it!
