PROBLEM TO BE SOLVED: To form spectacle lens bodies in such a manner that only the directions to be viewed are made distinctly visible and that the circumferential directions thereof are made visible in light shielding and polarizing states by admitting the rays in the directions to be viewed as they are and shielding and polarizing the unnecessary rays entering from the circumference. SOLUTION: The translucency degrees of the direct viewing direction portions and the circumferential direction portions exclusive of the direct viewing direction portions of the spectacle lens bodies 1 are changed to make the translucency degree of the direct viewing direction portions 5 larger than the translucency degree of the other circumferential direction portions 6. The direct viewing direction portions are otherwise constituted as transparent portions and the other circumferential direction portions constituted as light shieldable or polarizable portions or the direct viewing direction portions are bored with see-through holes and the other circumferential direction portions are constituted as the light shieldable or polarizable portions.
