摘要： The present invention provides an ophthalmologic apparatus that can noninvasively measure the state of the lacrimal layer formed on the cornea surface and that can quantitatively measure the state of the lacrimal layer without utilizing a reflection image from the retina.The ophthalmologic apparatus according to the present invention comprises an optical projection system for projecting light of a specified pattern onto a cornea surface, and an imaging device for photographing a reflection image of the projected light from the cornea surface. An operating unit calculates the degree of distortion of the reflection image on the basis of the density value distribution of the image photographed by the imaging device. The operating unit can determine the state of the lacrimal layer using the calculated degree of distortion.
