These camera glasses have a very good picture. 1080 HD for video and 4K for photos. Pay close attention to that as these glasses do not record video in 4K. They look pretty cool as they are more of a stylish pair of camera glasses and they come with 3 different sets of lenses. Dark lenses, yellow lenses and clear lenses. The best part is these glasses work with an app via wifi where you can review and download what you just recorded instantly. Viidure is the app they offer for these glasses. The app works very well with no issues. The only 2 knocks on it is that the setting for time recording loop always defaults to 3 min when the camera is turned off. The other is that when you access the SD card via the app the camera glasses start recording immediately for some reason. Other than that the app works pretty well. The recording time on a full charge battery is about 105 min which is pretty good. Charging the camera does take a little bit of time but not a big deal. You can record while charging the camera with a power bank or whatever you choose to charge with. There is a blue light in the middle of the nose section on the glasses that indicate you are recording by flashing. This light is visible with the glasses on from the inside. Press the record button on the right hand side and the camera records. Press the button again and the camera stops recording.
