Recent advance in visual display terminals forces us to engage in much visual tasks in near sight, which causes asthenopia. The authors have developed a new visual presentation method, in which the distance of visual image from user's eye moves between near and far locations periodically to keep the field of view unchanged. The method can enable the user to relieve eye accommodation strain unconsciously. In this paper, the principal and the developed prototype are introduced followed by preliminary evaluation results measuring the refraction.
