to read at comfortable distance. Most people are comfortable with a reading distance of 10 to 12 inches.

A book magnifying glass consists of a magnifying
lens mounted on to a lens holder.
As the power
of a magnifying glass for books increases the diameter of the lens decreases and the field of view is smaller
A book magnifying glass with light will provide better
magnification results as they provide a sharper image. Magnifiers decrease light transmission.
