Abstract
A rear vision mirror for a vehicle is disclosed, which includes a main body unit and a mirror unit. The main body unit is mounted to the outside or the inside of the vehicle, to support and protect the mirror unit. The mirror unit mounted to a front side of the main body unit displays images of other vehicles and objects existing at left and right rear sides of the vehicle. The mirror unit is sectioned into at least two regions each having different eccentricities and refractivities, thereby constituting an aspheric progressive mirror. The rear vision mirror is capable of preventing dead zones, an image distortion, an incorrect sense of distance, and dazzling.
Claims6
A rear vision mirror for a vehicle, comprising:
- a mirror unit in the form of an aspheric progressive surface mirror sectioned in a horizontal direction into at least three aspheric progressive regions having respectively different refractivities and eccentricities;
- and
- a main body unit mounted to a vehicle body, while supporting the mirror unit,
- wherein the refractivity and eccentricity of the sectioned region of the mirror unit are gradually increased from an inner region toward an outer region in a manner that, more specifically, refractivity of the inner region is gradually increased from the middle thereof toward a border with a middle region until being equalized to that of the middle region, and refractivity of the middle region is gradually increased from the middle thereof toward a border with the outer region until being equalized to that of the outer region.
