Abstract: An optical apparatus applied to ophthalmology detection is disclosed. The optical apparatus includes an image capturing unit, a data comparing unit, a detection unit, a location determining unit, and a data output unit. The image capturing unit captures images of different portions of a face of a person to be tested to obtain a plurality of face images. The data comparing unit compares the plurality of face images with a built-in database. The detection unit detects on an eye of the person to be tested. The location determining unit automatically determines whether the eye detected by the detection unit is left-eye or right-eye. The data output unit selectively outputs a detection result of the detection unit, a comparing result of the data comparing unit, and/or a determining result of the location determining unit.

Abstract: An image-recognition assisting method includes the steps of using an examination instrument to generate an image having a split-image area formed thereon; setting a region-of-interest (ROI) around the split-image area of the generated image; performing a pixel luminance addition processing on the ROI, so that all pixels in the ROI have increased luminance contrast; and performing a contrast correction on the ROI having increased luminance contrast, so that the luminance contrast between the split-image area and the area surrounding the split-image area in the ROI is further increased. The image-recognition assisting method optimizes the image generated by the conventional ophthalmic examination instrument, such as a fundus camera, to increase the sharpness and the luminance contrast of the image output by the fundus camera, so that an examiner can easily recognize two offset rectangular image parts in the split-image area and align them with each other to focus the examination instrument.

Abstract: An air-puff type intraocular pressure measuring device includes an optical measuring unit and a puffing unit. The optical measuring unit includes an imaging optical path having a perforated lens and an image sensor capable of receiving an eyeball image via the perforated lens for eyeball alignment; a measuring optical path having a measuring element for transmitting a measuring signal and receiving a reflected signal via the perforated lens to derive an intraocular pressure value; and a beam splitter for the image sensor and the measuring element to respectively form a first and a second path having different axial directions. The puffing unit is connected to the optical measuring unit for puffing air through the perforated lens against an eyeball. The puffing unit has a puffing path located coaxially on the second path of the measuring optical path, so that measuring errors caused by parts-related tolerances are effectively reduced.
