An eye-fatigue examining device and an eye-fatigue examining method capable of examining eye fatigue of a subject's eye regardless of an age of a patient are provided. The eye-fatigue examining device includes: a light quantity difference adjusting unit that increases a light quantity difference between lights respectively incident on right and left subject's eyes; a gaze direction detecting unit that detects gaze directions of the respective subject's eyes while the light quantity difference adjusting unit increases the light quantity difference; and a light quantity difference deciding unit that decides a specific light quantity difference at which a change in the gaze directions due to the increase in the light quantity difference occurs, based on the detection result of the gaze direction detecting unit.

Technologies are described image a treatment area during laser treatment using a time-gated image capture device and an electronic display. During laser treatment, a physician may monitor a treatment area to ensure efficacy and to prevent over-treatment. Light reflected from the area that includes treatment area may be detected by an image capture component and converted to a signal. An image processor may then generate image data based on the signal and provide the image data to be displayed on an electronic device. A gating component may send instructions to the image capture component and/or the image processor to prevent inclusion of light from one or more laser pulses generated during treatment. Excluding light from the laser pulses may prevent glare in captured images allow a monitoring physician to safely and accurately monitor the treatment area.

An OCT system for generating images of an anterior or posterior segment of an eye is described. The system includes a light source, a controller, optics, a detector, and a processor. The light source generates a beam of light and is capable of operating in a posterior or an anterior segment imaging mode. In the posterior segment imaging mode, light source outputs light with a first spectral bandwidth of less than 120 nm and including wavelengths between about 1060 to 1070 nm. In the anterior segment imaging mode the light source outputs light with a second spectral bandwidth that is larger than 120 nm. The controller enables switching between the posterior or anterior segment imaging mode.

An optometer may include a test object including a point light source and a collimator lens configured to collimate light from the point light source. The optometer may generate, for a user viewing the point light source through the collimator lens, an image of the point illumination source on a retina of an eye when the eye is in a rest position without triggering the eye to focus. A user-perceived deviation of the image of the point source from an in-focus image is indicative of visual refractive error of the user. A user may use the device with a naked eye to gauge visual refractive error of the eye or may use the device with corrective lenses to gauge the efficacy of the corrective lenses.

Systems and methods are disclosed to inspect an eye includes capturing an eye image using a mobile device camera; extracting features of the eye; applying a deep learning neural network to detect potential eye damage; and reporting the potential eye damage for treatment, such as those from laser pointers, among others.

The present invention provides a method of diagnosing, or developing or monitoring a treatment regime for, an ocular condition in a subject based on detected physical behaviour in a tear film, or lack of tear film, in the subjects eye, the method comprising the steps of: (a) capturing from the subjects eye at least a first captured data set; (b) identifying at least a first comparative data set; (c) analysing the at least a first captured data set relative to the at least a first comparative data set, thereby detecting physical behaviour in the tear film; and (d) diagnosing, or developing or monitoring a treatment regime for, the ocular condition based on the detected physical behaviour of the tear film. Also provided are methods of selecting contact lenses, of evaluating the effects of wearing a contact lens, and of determining preferable wearing periods of contact lenses and rest periods from wearing contact lenses by subjects.

An ophthalmic instrument including a light emitter, an optical system, and a control section. The light emitter includes a light source including at least one out of a first light source unit or a second light source unit that emits light for examining a subject eye. The light emitter is configured to emit light from the light source. The optical system guides light emitted from the light emitter onto a right-eye retina and/or onto a left-eye retina. The control section is configured to control the light emitter and the optical system such that the light is shone onto the right-eye retina and/or onto the left-eye retina.

An ophthalmic instrument includes a carrier positionable relative to a test subject, and first and second measurement units mounted on the carrier by corresponding first and second parallelogram linkages. The first measurement unit, for example an autorefractor/keratometer, performs a first type of ophthalmic measurement, and is guided by the first parallelogram linkage to move relative to the carrier simultaneously in forward and downward directions from an idle position to a measurement position. The second measurement unit, for example a tonometer, performs a second type of ophthalmic measurement, and is guided by the second parallelogram linkage to move relative to the carrier simultaneously in forward and upward directions from an idle position to a measurement position. The first and second measurement units may each have a respective optical axis which aligns with a fixed measurement axis of the carrier when the measurement unit is in its measurement position.

An ophthalmologic apparatus that inspects a subject eye of a subject. The ophthalmologic apparatus includes an optometry device for inspecting the subject eye, a base for supporting the optometry device, an face supporter for holding the subject eye at an optometry position by supporting a face of the subject, and a changing device for relatively changing a positional relationship between the optometry position and the base in a working distance direction of the optometry device.

The present application includes methods, systems and computer readable storage devices for determining a color score for at least a portion of a biological tissue. The subject matter of the application is embodied in a method that includes obtaining a digital image of the biological tissue, and receiving a selection of a portion of the image as an evaluation area. The method also includes determining for each of a plurality of pixels within the evaluation area, a plurality of color components that are based on a Cartesian color space, and determining, from the color components, a hue value in a polar coordinate based color space. The method further includes determining a color value based on the hue value for each of the plurality of pixels, and assigning a color score to the evaluation area based on an average of the color values of the plurality of pixels.
