I have the bernina magnifying glasses. They fit just above the needle area and personally stopped using them as it was so difficult to get a clear focus.
Not sure about the video.
have you thought about trying to tip the machine? This would help your neck more than the other ways. Try usin a thin book under front of machine until it comes a comfy slope, this is what I do as I have neck issues. The front isn't level but my back of machine stays on back place.
Good luck.
