Meet the Varia Vision: a smart wearable device that turns your cycling sunglasses into smart glasses, providing you with performance data, turn-by-turn directions, smart notifications, and more on the go. It can also warn users of traffic coming from behind.
The device has 8 hours of battery life. You can attach it on either side of your glasses. The eyepiece is adjustable. Vision offers vibration alerts for navigation, notifications, and performance. It will be available for $399.99 later this year.
