The use of magnification will greatly enhance the practice of dentistry. A factor of x2.5, with a focal distance of 15 to 18 inches, is the most commonly used magnification combination. This allows the operator to work erect, with the spine supported against the seat back.

Some loupes allow the attachment of high intensity halogen lights running from mains power or battery packs. Magnifiers are available for less than £100 but good optics provides better quality vision. Suppliers of high quality optics are Keeler, SurgiTel and Designs for Vision.
