A system and method for assisting the application of a contact lens to a wearer's eye includes a contact lens support having a viewing tube and a light transmitting tube. A first end of the light transmitting tube is positioned proximate a distal end of the viewing tube, while a second end is exposed to a light source. Light from the source is transmitted through the tube to create a lit fixation target at the first end, ensuring proper gaze alignment during lens application. In one embodiment, the light transmitting tube is a fiber optic shaped to convey ambient room light, with perpendicular local optical axes at its ends. In another embodiment, a passive radioluminescent source, such as tritium gas exciting a phosphorescent material, provides power-independent illumination. The recessed target generates a parallax effect, restricting visibility to a narrow angle for precise gaze alignment and lens placement.
