Magnifying glass suggestion
As magnification goes up in a magnifier, lens size goes down. A 2x magnifier, such as the Bausch & Lomb 2" x 4" Rectangular 2x may have a lens size of 4 inches. This would be suitable for reading a book or text or just taking a look at things in general. On the other hand, a 10x magnifier, such as the Nikon 10x Jewelry Loupe Jeweler Pocket Round Magnifier - 6947 will have a lens as small as a 1/2 inch or less and will therefore offer a much smaller "window" to see things. Unfortunately, you can't have it both ways, so you need to decide if magnification or if lens size is more important for your application. For reading, I'd stay with a larger size magnifier. The highest you can go would be 5x, such as the Bausch & Lomb 5x Aspheric Magnifier 81-31-22. This will have a lens size of about 2 inches, which is still large enough for reading.
