Wanting a bit of info on video glasses. Can you wear your prescription specs under the video ones so that half blind old blokes can see what they are videoing? The second question is where do you get them? I find its a bit hard to hold a camera and fly at the same time. I could use my go pro but I find that it takes about 5 hrs to upload a 4 min video. After something with a bit less resolution. TIA.
