Hand magnifiers offer a working range that is usually greater than that of spectacles, and come in different styles that can be used for reading, or short-term tasks such as seeing labels, dials, and price tags.
Hand magnifiers are easy to manipulate for patients who view eccentrically, but may be difficult for those with grip problems or tremors. Variations in hand magnifier design include self-contained illumination, aplanatic (2-lens) and multi-lens systems, and a variety of handle types for maximum utility. The effective power of a hand magnifier is dependent upon the glasses with which it is used (distance or near correction) and the distance at which it is held.
Handle design, weight, portability, illumination and lens power are all features that influence prescribing to meet patient needs.
