A portable intelligent multi-function phoropter is disclosed. The phoropter comprises a casing, a plurality of control elements, two adjustable eyepiece modules, a plurality of micro motors, a liquid crystal display module, a control module and a power supply module. The casing of the present invention is small so that the overall volume is small, and it is convenient to carry and use. The present invention has many test patterns, so different vision tests can be performed. With the combination of convex lens and concave lens and the application of existing electronic components, the overall price is reduced. The invention satisfies the market demand for the phoropter.

System, methods and apparatus for providing telepresence robot vision screenings, and eye examinations via at least one of a plurality of telepresence robot eye examination systems anywhere in the world. A telepresence robot enhanced and adapted with at least one electronic device configured to be connected to at least one eye examination equipments of any maker. Whereby a human controller with a electronic device running mobile application and/or softwares can remotely control the robot to navigate and perform an indirect to direct eye examination and vision screening to at least one user located near the telepresence robot location. The system internet connection via wifi, bluetooth and/or cellular wireless network connection (4G, 5G and/or greater) to receive a connection from a controller. A eye examination, vision screening and/or medical referral is provided to at least one user via remote printing device and/or encrypted email.

The invention relates to cylindrical tunable fluidic lenses. The cylindrical optical power of the lenses may be continuously tuned within at least ±10 diopters, without inducing any significant spherical aberration, or any other significant aberrations. The lenses feature a geometry that produces minimal or no spherical defocus. These cylindrical tunable fluidic lenses could be used to induce and/or correct cylindrical optical aberrations in adaptive optical systems, particularly in ophthalmologic applications related to objective and automatic assessment of the refractive error of the eye, without the need of receiving feedback from the subjects.

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.

An apparatus, and corresponding method, for determining a property of an eye includes a housing with a proximal port that receives an eye and also light from the eye. The housing further includes a distal port, and the two ports together form a visual channel providing an open view to enable the eye to see target indicia external to and spaced away from the housing. A wavefront sensor within the housing is configured to receive the light from the eye via the optical path and to measure a wavefront of the light. A determination module determines an objective refractive correction based on the wavefront and predicts a subjective refractive preference of a person having the eye based on the objective refractive correction. Embodiments can be handheld, and binocular, and predict subjective refraction based on demographic and other information.

Disclosed is a device for placing a phoropter head in a horizontal position in order to optimize the measurement of the visual acuity of a patient, and to a method for placing a phoropter head in a horizontal position. The device and method help performing a correct measurement of a patient's visual acuity by allowing the fine adjustment of the phoropter head horizontality and alerting when its position is not correct.

There is provided a method and a system for intelligently determining an eyeglass prescription of a patient. The method, executed by a processor, includes: obtaining patient information from the patient to generate initial sphere, cylinder, axis, add, and prism values; performing measurements to generate at least one updated sphere, cylinder, axis, add, and prism value based on communication with the patient; repeating the performing measurements to generate optimized sphere, cylinder, axis, add, and prism values; and outputting the optimized sphere, cylinder, axis, add, and prism values to a database.

A system for conducting an automated refraction examination on a patient, including: a phoropter configured to present different optics to the patient; an automated reading rod mounted to the phoropter; and a control unit configured to send signals to perform an automated refraction examination; wherein the phoropter comprises a right member with a right aperture and a left member with a left aperture; wherein the automated reading rod comprises: a reading rod including a first end and a second end; a motor coupled to the first end of the reading rod, wherein the motor is configured to drive the reading rod between a first position and a second position; a mounting interface configured to mount the automated reading rod to the phoropter; a reading card holder coupled to the second end of the reading rod; and a reading card coupled to the reading card holder.

A system for administering a subjective refraction test on a patient includes a phoropter having a plurality of lenses, a display device, and a computing device coupled to the phoropter and the display device. The computing device is configured to generate a script corresponding to a first set of conditions for a first sub-test of the plurality of sub-tests, receive an input indicative of the patient's vision under the first set of conditions, determine an endpoint for the first sub-test of the plurality of sub-tests based on the input, communicate a signal to the phoropter and the display device causing the patient to be presented with a second set of conditions in response to the input, generate and display an updated script corresponding to the second set of conditions, wherein the updated script provides a prompt for updated patient feedback under the second set of conditions.
