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 system for replicating a standardized visual acuity test, such as the 20′ Snellen test may comprise a binocular viewer attached to a smartphone. A binocular viewer may comprise a housing comprising a pair tube covers having voids allowing for viewing through a pair of lens tubes with each lens tube in visual communication with a second lens a first lens an aperture and a front cover. The optical systems use an artful combination of front and back lens surfaces, demagnification and other systems to faithfully replicate the sight lines perceived by a user of a traditional 20′ test. The system also allows for the incorporation of other tests conducted with both eyes including Color Sensitivity and Contrast, furthermore by placing a deformable, tunable lens between the second lens and the eye the device serves as an ophthalmic refractometer, allowing a Spherical Equivalent refraction estimate for each eye.

A remote eye examination method includes initiating a remote chat session between a local computing device coupled to a phoropter, and a remote computer, and initializing the phoropter for remote control by the remote computer. Then, a multi-colored lamp is activated in a first color until a determination that a refractory examination utilizing the phoropter has commenced. Thereafter, responsive to a determination that the examination has commenced, the multi-colored lamp changes to a second color, and movement of portions of the phoropter are commanded as directed by the remote computer, data is recorded into a patient record and a progression of the examination monitored. Finally, on condition that a threshold period of time before a conclusion of the refractory examination is detected, the multi-colored lamp changes to a third color and upon conclusion of the examination, a message transmitted to a remote account indicating access to the patient record.

A system for ordering spectacles is provided. The system includes a virtual reality headset having a display and an adjustable lens assembly configured for selectively adjusting optical parameters thereof. The adjustable lens assembly is disposed with respect to the display such that optical path between is adjusted in accordance with the optical parameters. The system further includes a server having a database of images of eyeglasses frames, an input device configured for selecting a frame from the server, and a controller configured to adjust optical parameters of the adjustable lens assembly to correct vision impairment and to display on the display virtual reality images simulating view through the selected frame with lenses having the optical parameters.

A first information processing device acquires an instruction signal for instructing an operation of a subjective optometry device, and transmits a drive signal for causing the subjective optometry device to operate as instructed by the acquired instruction signal to the subjective optometry device. When the first information processing device is remote-accessed by a second information processing device, the first information processing device can acquire the instruction signal input to the second information processing device by a user via a network. The first information processing device can further acquire a response input by an examinee who visually recognizes a presented target, and can further generate an instruction signal instructing the operation of the subjective optometry device based on the acquired response.

A virtual reality display system including at least one optical alignment subsystem optically aligned with at least one eye of a subject and at least one virtual reality display device optically aligned with the at least one optical alignment subsystem for displaying to the subject at least one virtual reality object undergoing virtual motion, wherein the virtual motion of the at least one virtual reality object as viewable by the subject is operative for inducing and relaxing accommodation by the at least one eye of the subject.

A mobile ophthalmic unit is disclosed. The apparatus is comprised of the following components: a phoropter on an adjustable arm, an extendable slit lamp, an ophthalmoscope with controller, desktop or a laptop computer (or both) with or without a detachable screen or a tablet computer, a WiFi router and an internet hotspot. All of the aforementioned components are connected to a mobile desk having locking caster wheels. An object of the invention is to allow an eye care specialist to visit patients in the field and perform routine eye exams remotely rather than requiring patients to travel in order to obtain eye care. For example, the ophthalmologist can easily roll the apparatus into a cargo van and drive to an underserved population and deliver eye exams where no such facilities exist—thereby enhancing eye care for a community.

A face shield for use with phoropters is described with methods for using the same. The face shield includes a central cavity, which is defined by a front wall and one or more sidewalls extending outwardly from a perimeter of the front wall. The central cavity is configured for surrounding a nasal region, an oral region, and a mental region of an adult person's face. The face shield includes one or more attachment features extending outwardly from the central cavity and configured for attaching the face shield to the phoropter. A method for securing a face shield including attachment features and a central cavity defining an upper cavity region, a middle cavity region, and a lower cavity region to a phoropter is described. The method includes positioning the upper cavity region between lens housings of the phoropter and attaching the attachment features to securing components of the phoropter.

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.

Disclosed is a hoist apparatus including: an electric motor, and a control box that can be electrically powered by a power supply, the control box including at least an electronic control circuit, an electrical wiring and an external casing forming a box of the control box, the external casing including at least sidewalls and a removable lid closing the box, the control box controlling the operations of the electric motor thanks to the electrical wiring connected to the electronic control circuit, to the power supply and to the electric motor, and a monitoring device, wherein the monitoring device is an insert of the box, the monitoring device being arranged within an enclosure, the enclosure being an added part of the box or being an exchanged part of the box and wherein the monitoring device is connected to the electrical wiring.
