Review on Glasses Horizontal Spectacles Watching Presbyopia by Tiffany Smith

Pros first. I think it's a great concept. The glasses are well made. Nice solid build. The glasses sit comfortably on the face when lying on your back, so you hardly feel their weight (heaviness is inevitable when using solid prisms). These glasses go well with reading glasses. The picture is clear. And the price is right for two of them. I was going to give it 5 stars but have to give 2 stars because of the shortcomings: 1. Narrow field of view, especially vertical. While I wouldn't mind more horizontal overlap for the left and right eyes, this is fine, although it feels like reading through a short tunnel. However, the vertical field of view is a problem. It's okay to read your phone. But with any other reading material (a full-size book, let alone a magazine), you can't see the entire page without tilting your head up and down or moving the book up and down. This defeats the purpose of these "lazy" glasses. You can't just lie in one place and scan the page with your eyes. You have to constantly move parts of your body to read.2. The viewing angle is only tilted 60 degrees, not 90 degrees. I tested this by laying the glasses on their side and pointing the laser beam through one of the prisms in exactly the same direction your eye would be pointed by measuring the deflection of the beam. It was 60 degrees. That means you can't lie on your back with a book on your stomach. You need to lift the book in the air or tilt your head forward (bend your neck). If you wear reading glasses, you can position these prism glasses so that the temples rest on the temples of the reading glasses by tilting the prisms slightly downwards.3. Misleading Advertising. The description says the viewing angle is tilted 90 degrees. It's not like this. The comfort of bending your neck and moving your head or reading material to read is also not appropriate.
