The comfort and quality of vision of progressive lenses are determined by several factors such as the
measurement and placement of the lens, the position of the head when examined, and the adjustment of the
eyeglass frame when the lens parameters are measured. This research illustrates how the comfort and quality of
vision can be affected by these factors. This research was conducted on those who have examined and installed
progressive lenses based on their experience and abilities. The results showed that the visual quality of
progressive lens wearers was influenced by the measurement of monocular PD, vertical pupils with reference to
the lower rim of the rim and the center of the pupil,. head position factor when looking far must be in a straight
or primary position, factors that affect the quality of vision where far vision must be clear through progressive
lenses , quality near vision must be clear and distance vision medium clear.
