Let me start by saying that I haven't had any problems with either the delivery or the product itself. I've looked at reviews of refractive glasses, including many of these types. I found them to work well, but the lenses are so thick that they get uncomfortably close to the eyeballs when worn on the face. I chose these instead as you can't wear them as glasses and use them as a camera lens. (I really don't know why they did that; it's not that you can't use glasses for that. They actually made glasses specifically for smartphones, but they've been sold out for a long time and I don't know if they'll ever come back)
