I purchased this in a set of two. These are prescription glasses, but I'm not sure of the details, so it's difficult for me to provide them. I have presbyopia, but these are adjusted to see distant objects, just for watching movies. They are not adjusted for close-up work. I've used them a few times. The other pair is sufficient, and I no longer need these, so I'm selling them. They are not completely black, but have a slightly gray tint. The nose pads are not adjustable, so you'll need to have the ear pieces adjusted at an optician to fit your face.
