Eyeglasses, Frames, Trial

Definition : Devices designed to hold lenses in an appropriate position in front of the eyes during an ophthalmic lens and frames trial procedure. Trial frames include graduated arcs and a linear rule to determine the lenses' angular positions and to measure the interpupillary distance; the frames usually allow the installation of several (e.g., 3) trial lenses simultaneously. Trial eyeglass frames are used in examination procedures to determine the lenses and eyeglass frame characteristics needed for a particular user, including a good frame adjustment to the nose and ears position.
