The ergonomic refraction station and procedure of use consists of a phoropter helmet, chair, work table, monitor and electronic circuit, which seeks to perform a refraction test in the conditions most similar to the usual work environment of the examinee, for this it consists of a lightweight phoropter helmet, which adjusts to the size of the user, made of transparent material to allow contact with its surroundings and execute the usual movements of head, neck, eyes and working distance, parameters that are captured by optical, distance and inclination sensors, located on the phoropter helmet or on the flexible and adjustable table with swan neck arms, so that once the patient places the phoropter helmet and sits on the chair and table, the sensors send information to a microprocessor that shall recognize the real working conditions of the patient and adapt them to the conditions of the ergonomic refraction station, such as: size of letters, aligned inclinations of head-eye-hand coordination with the vision charts, lighting and thus adequately projecting the reading chart on the table and the characters and graphics that the examinee shall read; It also includes removable multifocal lenses or in a test case with the appropriate coupling, noncircular eyepieces with a greater visual field than the traditional ones for the far, middle and near vision test and ocular covers.

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.

A method for carrying out an eye examination on an examinee is provided. The method includes providing a display configured for displaying a visual stimulus; forming a visual path between the display and at least one eye of the examinee; displaying on the display at least one visual stimulus having visual characteristics; detecting reflexive eye response of the at least one eye in response to the displaying of the visual stimulus; assessing vision of the at least one eye in accordance with the reflexive eye response and the characteristics of the visual stimulus.

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.

A process, phoropter, and an optometry system, the process being for correction of the shift of the optical power of an active lens in a phoropter due to a temperature change over time, the active lens including a container filled with a liquid and having a deformable curvature membrane under the action of an actuator controlled by an optical power control command, the shift being that the active lens provides an actual optical power that is different from the expected optical power corresponding to the optical power control command. A temperature sensor is arranged in and/or on the phoropter to measure the temperature in the phoropter.

A vision-compensating device allowing observation along an optical axis of observation with an optical correction of variable power includes a lens having, along the optical axis, a spherical power that is variable as a function of a first control, and an optical assembly generating, along the optical axis, a cylindrical correction that is variable as a function of at least one second control applied to the optical assembly. The vision-compensating device also includes a module for receiving at least one setpoint for the optical correction and a module for determining the first control and the second control depending on the setpoint by way of a mode taking into account the distance separating the lens and the optical assembly. A method for controlling a vision-compensating device and a binocular optometry device are also proposed.

A refractor (100) includes: an enclosure having a front face containing a first optical window and a back face containing a second optical window aligned with the first optical window along an optical axis of observation; and at least one vision compensating device making it possible to observe along the optical axis of observation. The vision compensating device includes, between the first window and the second window, a first optical element having a spherical power along the optical axis, the spherical power being variable. The enclosure is mounted on an orientable holder (104) that is rotatable relative to a stationary portion (102) about a horizontal axis (H). A method for measuring refraction employing such a refractor is also disclosed.
