The slit lamp microscope comprises: a slit light optical system (35) including a slit lamp (32), and a reflecting mirror (34) or prism for reflecting a slit light from the slit lamp (32) toward an eye of an examinee and a microscope unit (38) including an object lens (50), binocular eyepiece lenses (52), a magnification changing section (54), which changes magnifications of an image formed by light passing through the optical paths, being provided between the object lens (50) and the eyepiece lenses (52), and an inward angle changing section (56), which changes a binocular viewing angle, being provided therebetween. A focal distance of the object lens (50) is made shorter, by an optical path length of the inward angle changing section (56), than that of an object lens equipped with no inward angle changing section. The inward angle changing section (56) is located closer to the object lens (50) than to the magnification changing section (54).
