An ocular disease detection device is constructed having a defocusing mechanism that causes eyes of a subject to be defocused. This is primarily accomplished by providing a beamsplitter at a first focal distance from the eyes and projecting an image at a second focal distance to the beamsplitter and then to the eyes. This presents an image having two focal lengths therein to the subject, which defocuses the eyes. A beam generator and camera are mounted so that their respective axes are closely proximate each other and serve to illuminate and receive images of the defocused eyes via the beamsplitter, respectively.
