PURPOSE: An aspheric optical lens is provided to prevent a blind spot by applying an aspheric optical design. CONSTITUTION: A convex part(120) is convexly formed based on a virtual central axis. A slant part(130) has a constant slant angle toward the virtual central axis. A concave part(140) is concavely formed on the end of the slant part. An another slant part(210) has a tilt angle from the virtual central axis to the point separated from the central axis. An another block unit(220) is convexly formed from the end of the another slant part.
