The most popular magnification for higher magnification projects is 2.5x lens, which gives you a focal length or working distance of approx 8″ inches for that magnification, for some this headband magnifier magnification might be to much power and to short of a focal length or working distance for comfortable use. For more extended repeated use where slighter magnification is sufficient a 1.5x lens provides a more comfortable focal length or working distance of 20″inches, at this distance the focal length is very wide and much more comfortable for extended use projects and tasks. The relationship of of magnification is focal length is an inverse one, as magnification goes up, the focal length working distance goes down, this relationship must be kept in mind when shopping for a headband magnifier or any other magnifier or magnifying glass.
