Abstract: A simple diagnosis assisting device (10) for keratoconus and/or astigmatism, including a mobile terminal (10A) including a camera (2) and a transceiver function (3), and integrally or separately provided with a light source (1) for simultaneously projecting ring light onto both eyes. The light source (1) emits the ring light upon being attached to the mobile terminal (10A) in a case of being separately provided to the mobile terminal (10A), and emits the ring light from the mobile terminal (10A) in a case of being integrally provided to the mobile terminal (10A). The camera (2) simultaneously captures a projected image of both eyes onto which the ring light is projected. The ring light may be multiplex ring light or simplex ring light, and is configured in a ring shape by a plurality of point light sources or is configured in a ring shape by a single linear light source.
