The present invention aims to provide an agent for treating meibomian gland dysfunction. The present invention provides an agent for treating meibomian gland dysfunction, which contains activated vitamin Dor a derivative thereof as an active ingredient.

Agent for treating meibomian gland dysfunction

After an optical element and more preferably both an optical element and an electrical element are mounted on a substrate an upper clad of optical waveguide is formed, covering these elements, and thereby a structure of hermetic seal is achieved through the use of the upper clad

Optical module and manufacturing method thereof

A optical displacement sensor comprises optical output detecting unit for detecting an optical output from the semiconductor laser, which changes in accordance with the phase of return light reflected by the external reflection unit, when an optical distance between the semiconductor laser and the external reflection unit changes at a change rate, optical distance modulation unit for changing the optical distance at predetermined periods by an amount of modulation of the optical distance at a rate higher than the change rate, and a detection circuit system for detecting the amount and direction of change of the optical distance based on an optical output from the optical output detecting unit detected in synchronism with a timing of modulating the optical distance by the optical distance modulation unit.

Optical displacement sensor

The present invention comprises a compound cavity in which a vertical-cavity surface-emitting laser and external mirror are combined, and the change in intensity of a laser beam or in mirror loss is detected by the detection unit. The detection unit includes a photodetector for directly detecting a variation in intensity of a laser beam, and PN junction potential difference detecting device for detecting a variation in mirror loss created due to a relative displacement between the external mirror and the vertical-cavity surface-emitting laser, based on a change in carrier density within the surface-emitting laser. The phase of the laser beam returning from the external mirror is determined by a relative displacement between the external mirror and the vertical-cavity surface-emitting laser, and the laser beam output varies at a period of a displacement amount corresponding to 1/2 of the wavelength of the laser beam. Such a displacement amount is calculated by the counting device and the operation device.
