In fact, the term of reading glass had a special meaning in the eighteenth and nineteenth centuries. Reading glass was just a form of magnifier. The very beginning form of reading glasses was hand-hold with a single lens that was large. People held these reading glasses a few inches above the reading matter but at a considerably distance from the eyes. This was the most comfortable position to use these reading glasses. Many museums still possess primary reading glasses. Some of them were made of silver or gold frames. The lenses of them were usually oval.
