The present invention relates to a device for observing the meibomian glands enables a ready observation necessary for examination without a direct contact of an examination probe to the eyelid and an observation of all of the upper and lower meibomian glands in a relatively short time. A device for observing the meibomian glands, comprising: a light source radiating light containing infrared rays, a visible light-cutting filter that is opaque to visible light but passes at least a portion of infrared rays, an optical system for transmitting light from the light source that has passed through the visible light-cutting filter to the site being observed, an optical system for transmitting light from the site being observed to an infrared camera, an infrared camera, and a display for converting an image picked up by the infrared camera to a visible image and displaying the visible image; wherein the site being observed is a portion comprising the meibomian glands of an eyelid turned inside out, light from the light source is irradiated onto the site being observed, and light reflecting off the site being observed is picked up by the infrared camera. |
