摘要
PURPOSE: To enable a visual impression capable of reproducing a clear representation of an object in a space to achieve with a straight line by dividing a visual field based on cross-hairs or a concentric circle in which the lateral length of a micro-convex or a ring interval in the ring of the concentric circle is specified. CONSTITUTION: A number of lines are provided in a crossed grid system 2 produced by carving a glass surface of glasses or a contact lens or embeddable lens 1 using a laser radiation. The lateral length or the ring interval of a crossed micro-convex is set up in less than 0.5 mm, preferably from less than 0.5 to 0.05 mm. The division of visual field is carried out with a micro-convex of a point of which diameter is about 0.01 mm and lateral interval is about 0.05 mm. By this, a visual impression reproducing the representation of an object in a space can be consequently given with a straight line without containing the distortion of straight line and a 'stereoscopic photography'.
