A compact and portable device uniformly illuminates and magnifies the words, images, or other information on a surface, such as the words on a page of a book, while minimizing the amount of light transmitted beyond or away from the illuminated surface. The device employs a light transmitting body formed of a transparent light conductive material and a magnifying lens. The device also employs a housing with a light source and a power source for powering the light source. To receive and deflect light from the light source onto the underlying surface, the light transmitting body is configured to have a wedge shape tapering from a thicker edge to a thinner edge. The wedge-shaped light transmitting body and the magnifying lens may be integrally formed to allow seamless transmission of light between the light transmitting body and the magnifying lens.
