If you’re working with small objects, the X factor and field of vision are going to be the two biggest features. Depending on the size of the figures, you should look for a 5X or higher X factor so that the objects are properly magnified and ease the strain on your eyes. Likewise, you also need to consider the field of vision. You want the figures to be fully visible within the magnifying glass’ field of vision so that the glass can be held steady while you work.
