PROBLEM TO BE SOLVED: To increasingly heighten diffusion effect, by dividing a light from prism cuts formed on the object side into two directions to travel obliquely, thus by leading it into plural cylindrical cuts. SOLUTION: Blind cuts 4 of a lens 1 of a vehicle light are constituted by forming prism cuts 4a orthogonal to axes X and having an approximate V-shaped sectional on the object side surfaces of a foot part 3, and by forming cylindrical cuts 4b orthogonal to the axes X and having an approximate semicircular sectional on the visual line side surfaces. Thus, a light from the object is divided into two directions by the prism cuts 4a provided on the object side, and the light travels obliquely in the foot part 3, thereby the light enters plural cylindrical cuts 4b. Consequently diffusion effect is heightened increasingly. |
