| 摘要 |
The invention relates to a lens apparatus which cooperates with a mirror housing (14) on the side of a vehicle body. The lens may be a Fresnel lens (22) which acts to refract incident light from lower and/or forward scenes (Bl, B2) obscured from a driver's line of sight (54, 56). The lens (22) may be formed integrally with the mirror housing (Figs. 6a, 6b); or may be retrofitted via resilient straps (30) such that a portion (22d) thereof projects beyond a peripheral edge (14d) of the mirror housing (14). In the case of the retrofittable version, the plane of the lens relative to the mirror housing may be adjusted via a screw adjustment mechanism (40) connected to the lens (22) proximate two of its corners. |
