ZDNET’s key takeaways

The Engo 2 Photochromic glasses are available for $350 in standard and large shield sizes.
The glasses function as clear lenses or sunglasses, the heads-up display is bright and clear, switching metrics just takes a wave of your hand, and the glasses work well with Apple, Garmin, and Suunto watches.
The display is in a set position, so it takes a bit of practice to use it while viewing the path ahead. There is currently no support for Wear OS, Polar, or Coros watches.

I am a very competitive person and enjoy expressing this trait in athletics. Smartwatches and sports watches adorn both of my wrists so that I can capture my health and fitness data in an attempt to stay fit. I also subscribe to Strava, in part due to Strava Live Segments and the potential to earn Local Legend status when I run.

To track my running activities, I lift my wrist and glance at my watch, while sometimes having to scroll to view all the metrics I am interested in. When biking, I have a bike computer in front of me on the handlebars, and I glance down to view the data while sometimes using a finger to scroll to other metrics.

ZDNET RECOMMENDS Engo 2 Photochromic glasses The Engo 2 Photochromic lenses function as clear and tinted glasses with a heads-up display showing your most important workout data so you can focus on the activity. View at Engo

For the past several weeks, I’ve been running, biking, walking, and hiking with a pair of Engo 2 Photochromic glasses that have significantly improved my outdoor exercise experience. These are exactly the type of lenses that I have wanted for years, as they provide me with a crystal clear heads-up display so that I never have to glance down at my watch or bike computer again.

Not only do the glasses provide key metrics for the activity that I am participating in, but when the ActiveLook software is powering the display from the Apple Watch Ultra 2, I am presented with a unique Strava Live Segment view . The Engo 2 Photochromic glasses optimize the Strava experience, motivating me to work harder to PR on segments and earn more Local Legend awards.

In the ActiveLook software on your Apple Watch, you can select to view starred segments and those located around you to race against your own PR, other record holders, the carrot (your friend just ahead of you on the leaderboard), and the wolf (your friend that is just behind you on the leaderboard).

My time and distance behind the selected element appear on a visual arc over the top of other key metrics. These glasses make Strava a better real-time experience, so you don’t have to record data on the watch and then view it later at home after a shower.

The glasses are light at 36 grams and extremely comfortable. Still, it takes a bit of practice to get used to the large modules in the center of the glasses that house the battery, lenses, and sensors.

The display is located in the upper left corner of your right eye, just to the right of your nose bridge, so your focus bounces between it and the path ahead. I was able to get used to the view during my first run, but a bit is blocked by the hardware in the center of the glasses.

Speaking of sensors, the Engo 2 Photochromic glasses support gestures. This is one of my favorite functions, since I can easily switch between the metrics that I set up in the app with a wave of my hand in front of the glasses.

The glasses show three lines of data on the heads-up display in a vibrant yellow/orange color with clear fonts and three levels of brightness. You can customize what appears there using the ActiveLook smartphone app.

If you run intervals or have complicated training plans, the Engo 2 lenses are even more valuable, since holding up your wrist and scrolling through screens on the run can distract you from the road ahead and slow you down. Seeing your key metrics served up in your view, including those from your Garmin watch loaded with the ActiveLook data field, lets you wear your watch or mount your bike computer and keep your eyes focused ahead of you.

The battery provides up to 12 hours of data and the glasses are dust- and water-resistant, which means I can wear them all year long here in Puget Sound. I always wear glasses while biking, but rarely use them while running, and yet I have worn these for every run since they arrived. I am definitely buying my own pair to help me achieve my goals.

ZDNET’s buying advice

I test a lot of wearables in my attempt to find the perfect one that will motivate me to maintain a healthy level of fitness. I always thought some kind of amazing new watch would be key to this motivation, but it turns out that the Engo 2 Photochromic glasses for $350 are what I needed.

The Engo 2 also ensure that I will continue to be a Strava Premium subscriber. In fact, Strava should be heavily marketing these glasses, since they make the Strava experience so addicting.
