Configurations are disclosed for a health system to be used in various healthcare applications, e.g., for patient diagnostics, monitoring, and/or therapy. The health system may comprise a light generation module to transmit light or an image to a user, one or more sensors to detect a physiological parameter of the user's body, including their eyes, and processing circuitry to analyze an input received in response to the presented images to determine one or more health conditions or defects.

Systems and methods are provided for obtaining sight screenings, optical prescriptions and fittings for eyeglasses and contact lenses. A system can be self-operated through a voice-activated response system that enables an individual to determine one's own refraction, or can be operated with the assistance of a technician. A plurality of customer diagnostic locations can include digital equipment and optical instruments to conduct the sight screening. The data generated at these locations can be transferred to a remotely located eye doctor who interacts with a customer via a live audio-video connection to assist with interpreting the data, diagnosing the customer and operating the instruments at the locations. The eye doctor diagnoses, consults and authorizes the prescriptions for the customer. The customer's data can be sent to a lens laboratory to enable the fabrication, purchasing, and delivery of eyeglasses or contact lenses.

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.

An ophthalmic technician is present with a patient in an exam room to operate eye examination equipment and transmit patient information to remote location. At that remote location, a skilled technician is present to provide the necessary optical care, and may operate the phoropter from the remote location. Using video and/or teleconferencing equipment and a phoropter located in the patient examination room along with management software, the system works to determine the final optical prescription for the patient. That information, coupled with findings from other devices which are integrated with the management software, and that the patient uses locally, are reviewed by a remote-based optometrist or ophthalmologist.

The disclosure relates to a system for determining characteristic values of ametropia of a test person, comprising a device for generating optical test structures and a device for observing the test structures by the test person, said device comprising a correction unit for correcting possible ametropia phenomena of the test person. According to the disclosure, the optical test structures have at least two moving speckle patterns of different wavelengths. The disclosure further relates to a corresponding device for generating optical test structures for determining characteristic values of ametropia of a test person, and to a corresponding method for determining characteristic values of ametropia of a test person.

A portable device for the measurement of refractive error in the eye is disclosed. The device generally includes a liquid lens that the patient looks through, a projective array of static lenses, an electronic display, a system of electronics, and software that controls the potential applied to the liquid lens, controls the display, and runs the algorithm that processes patient feedback in order to determine the correct corrective lens powers. Housed in a singular body that can be held and positioned in front of the patient's eye, the device allows direct feedback and interaction by a patient using a remote control. Altogether, the device is automatically determines a voltage of the liquid lens that provides the patient with the clearest vision, which can be used to calculate the prescription corrective lens power.
