    Of all the most commonly used apparatus we all use is the optical
    visor. There are two very distinct uses for them. None of which is
    more important than as a eye-safety tool. When you are re-shaping
    your gravers or soldering pointer you will feel little shards of
    steel hit your face or cheeks. These little shards of steel often
    glance up and hit your cornea of your eye. The ensuing shock will
    cause you utter monosyllabic words of anguish and pain. 


    The end result is a trip to the hospital. But if you are wearing a
    closely fitting lens, such as "safety glasses" along with the
    optic-visor, your problems are almost at an end. Now the other use
    is of magnification, which to use? I, as a diamond setter, suggest
    using lens number 5 for all regular setting projects. I also use a
    stronger lends when for example setting 'watch bezels'. It is here
    that the focal length is shortened, but there is a stronger effort
    to wear these lenses on a longer period of time. Greater eye strain,
    head-aches ensue. So if you're attempting to wear the stronger lens
    for a longer period of time, don't! As a bench jeweller, you might
    be happy with a lens number 3, less eye-strain and with keeping the
    head farther away from the torch-flame.
