A medical system and method are disclosed herein. The medical system, in an embodiment, has computer-readable instructions configured to be executed by one or more processors to cause at least one display device of a wearable device to generate a plurality of graphics. The graphics are configured to stimulate a voluntary eye function of at least one eye of a subject, to stimulate an involuntary eye function of the at least one eye, and to block a vision of the at least one eye. The instructions are also configured to cause at least one sensor of the wearable device to sense eye movement, head movement, and pupillary resizing. The instructions are also configured to cause processing of a plurality of sensed eye parameters and any sensed head movement parameters and to generate an examination output that at least indicates a plurality of the sensed eye parameters.

A method for testing the eyes of a test person with the aid of a vision testing system as well as a vision testing system. A trial frame of the vision testing system is disposed in front of the eyes, said trial frame having at least one trial lens, at least one numerical value of an optical parameter which characterises the trial lens being recorded by means of a camera of a camera device of a display apparatus, said display apparatus being controlled by means of a control device of the vision testing system, said numerical value being identified by the control device by means of image processing, said numerical value being identified for a sphere and/or a cylinder and/or an axis and/or a prism.

The invention provides an advantageous system and corresponding method for measuring a plurality of aspects of vision. It is a computer-implemented, user-interactive system which can be used by practitioners such as opticians to measure and assess a patient's visual acuity. It comprises a handheld computing device arranged and configured to present at least one optotype to a user (patient) within a gamified environment. This aspect of the invention provides the advantage that it is more easily used by certain types of patients, such as children, the elderly or those suffering from medical/clinical conditions who would typically struggle to use traditional measuring tools. In a preferred embodiment, the optotype has at least one characteristic selected to facilitate the measurement of at least one, or preferably at least two, aspects of visual function; and the invention is arranged to detect the user's response to the optotype to provide a measurement of at least one or at least two aspects of visual function. Advantageously, this can be achieved in one sitting. The plurality of aspects of visual function can include visual acuity, central visual field, contrast sensitivity, stereopsis and/or colour vision, detection acuity of vision, resolution acuity of vision (spatial resolution or identification of static of dynamic directionality), recognition acuity of vision, hyperacuity of vision, temporal acuity of vision, spectral acuity of vision. The at least one optotype is repeatedly presented to the user, and the at least one characteristic is altered upon each repetition. The repetition may continue until a threshold or limit is reached. The at least one characteristic relates to the level of detail, contrast, colour, position or movement of the at least one optotype.

A technique for retinal images includes configuring a dynamic illuminator to illuminate the retina with an illumination pattern. An image frame of the retina is captured while illuminated with the illumination pattern. The configuring and the capturing are iterated to sequentially reconfigure the dynamic illuminator to illuminate the retina with a plurality of different illumination patterns and to capture a plurality of image frames each illuminated with one of the different illumination patterns. The image frames are combined into a composite retinal image.

An eye exercise device comprising a single open goggle chamber with no binocular or magnified optical lens of any sort having a front portion, protective first plate and second plate, light emitting diodes (LEDs), a control panel and a power supply, is disclosed. The control panel is coupled to the power supply, smart electronic glass and LEDs. The first plate is disposed at the front portion of the single open goggle chamber and the second plate is disposed behind the first plate. The second plate comprises a smart electronic glass and the first plate comprises a polycarbonate protective screen, disposed at a center region across an eye of a user. The smart electronic glass is configured to switch to an opaque state for short-sightedness and switch to a transparent state for farsightedness. The LEDs disposed at the periphery of the second plate is configured to emit light in a predefined sequence, thereby encouraging specific ocular movements.

A wearable device and a method of outputting a virtual image by the wearable device area provided. The wearable device includes a projection type display unit that includes a variable lens and configured to project a light forming an image, a first sensor configured to detect a light reflected from an eye of a user, and a processor configured to control to display the virtual image on the projection type display unit by controlling one of a location of the variable lens and refractive power of the variable lens based on retina image information corresponding to the detected light.

A method of automating the collection, association, and coordination of multiple medical data sources using a coordinating service application, computer, database, and/or server system to manage devices, examinations, and people involved in the medical examination and treatment process. In an embodiment, the method comprises authenticating a user for a premises, a device, or a device group, validating particular use of the device based on user credentials or type of device or device group, associating a medical examination with a patient or a medical examination schedule, associating medical examination data from a device or device group with a related medical examination session, routing medical examination data to a computer, database, or server, and pairing medical examination session data with a medical interpretation, clinical testing results, diagnoses, and/or other recorded information.

The present invention is directed to a medical imaging binocular indirect ophthalmoscope with onboard sensor array and computational processing unit, enabling simultaneous or time-delayed viewing and collaborative review of photographs or videos from an eye examination. The invention also claims a method for photographing and integrating information associated with the images, videos, or other data generated from the eye examination.

A machine arrangement, that sequentially processes sheet-type substrates, includes a plurality of different processing stations, one of which includes a non-impact printing device that prints the substrates. Further processing stations are a primer application device that primes the substrates and a dryer for drying the primer applied to the substrates. The primer application device and the dryer precede the non-impact printing device, in the direction of travel of the substrates. The processing station including the non-impact printing device, also includes a printing cylinder, on the circumference of which, the non-impact printing device that prints the substrates is arranged.

Various embodiments relate to systems and methods for performing eye examinations using an HMD that is able to present an image to each eye individually and then to both eyes simultaneously. Because the HMD, rather than a patient, controls conditions (e.g., glare, brightness) during the examination, test results are more likely to be accurate and reliable. In some embodiments, the HMD employs voice recognition to replicate the conversational exchange that would typically occur between the patient and the ophthalmologist or optometrist. The HMD may also be configured to change the visual environment experienced by the patient during testing. Further yet, the HMD, or another distinct computing system, may be configured to identify abnormal test results in real-time and, in some embodiments, the examination is modified accordingly. For example, tests scheduled to be performed during the examination can be modified or removed and new tests can be added.
