(Case 1) For eyeglass lens with small frame, pull up the lens holder and pull a
little more to find the near viewing zone center since the near viewing zone
center is nearby the bottom frame. (Picture : Small eyeglass lens)
(Case 2) For eyeglass glass lens with very small frames, near viewing zone
center is cut off sometimes. For such cases, press ‘MEM’ button at the point
where the horizontal indicator is minimized while abiding in the horizontal
allowance to set a near viewing zone center forcibly.
