ABSTRACT:
An improved lens for highlighting dents and including a narrow reference strip which is luminescent or of intensified light. A preferred embodiment of the lens having at least one light colored translucent strip adjacent at least one dark colored opaque strip and a narrow reference strip which is luminescent or of intensified light and which extends across at least a portion of the dark colored opaque strip. The characteristics of the reflected light from the luminescent or intensified light reference strip makes the reference strip stand out more than a reference strip which is not luminescent or of intensified light thereby facilitating the detection of dents.
