Abstract
An illuminated lens device for use in viewing authentication images is disclosed. The device includes a housing having a housing interior. The housing has a proximal end with a proximal aperture and an opposing distal end with a distal aperture. The lens device further includes a lens disposed at least partially within the housing interior. The lens is configured and positioned so that at least a portion of an authentication image is viewable through the proximal aperture when the housing is placed with the distal aperture aligned with and adjacent the at least a portion of the authentication image. The lens device also includes at least one light source disposed within the housing interior. The at least one light source is configured to illuminate the authentication image with light in a predetermined frequency range when the housing is placed with the distal aperture adjacent the authentication image.
