It’s really annoying that they all have a camera. One, they don’t need it. Two, it’s murder on the battery life. Every time I’ve looked to see if they finally made smart glasses without a camera they haven’t and the battery life for all of them is about four hours. Why the hell would I want something that I’m going to be using from when I wake up until I go to sleep only have the cool part I paid extra for work for four hours? I got a smart watch that runs for two days on a charge. If the watch can do it, glasses can do it.
