Abstract
The invention provides a method, system, and device for connecting loose trial lenses into a virtual reality (VR) headset, augmented reality (AR) headset, or other head mounted display. The system consists of two components: First, a component that is installed mechanically into the headset and which remains in the headset throughout the duration of its use. Second, a component which holds loose trial lenses and can be inserted and removed from the headset at will. The two components may connect to each other mechanically, magnetically, electrically, or by other means. In the magnetic system, both components contain embedded magnets that allow the second component to hold loose trial lenses inside the headset magnetically.

The detachable component 202 may include a dash and/or numbering system 203 which demarcates the degrees at which the trial lenses sit. As shown in FIG. 2, the base component 201 and the detachable component 202 may be attached via a mechanical mechanism. In this example, magnets are used to attach the two components together, but other mechanical systems may be devised.
[0029] FIG. 3 depicts lens adapter base component 300, in accordance with some example embodiments. The base component 300 may include a mechanical attachment point 301 where the detachable component can attach. This attachment point can be mechanical, electrical, magnetic, or otherwise. The base component 300 may also include a virtual reality (VR) headset specific attachment surface 302. This attachment surface may be specific to the virtual reality (VR) headset that the lens adapter component is being attached to.
[0030] FIG. 4 depicts lens adapter base component 400, in accordance with some example embodiments. The base component 400 may include mechanical attachment point 401 where the base component connects to the virtual reality (VR) headset.

Background
[0037] FIG. 1 depicts both single and a set of loose trial lenses. Loose trial lenses are used by eye care professionals (optometrists, ophthalmologists, etc.) in order to both diagnose vision problems—for example, prescribing glasses—and for correcting vision problems during an examination where refractive error must be isolated. An example of this is during a visual field test, where the clinician will use trial lenses to isolate the patient's refractive error and measure the eye's sensitivity to light in order to diagnose glaucoma and other diseases.
Trial Lens Adapters
[0038] FIG. 2 depicts a possible design for a detachable system that allows for a clinician to insert trial lenses into a virtual reality (VR) headset for use during an eye exam. There is a base component 201 that is clipped or permanently attached to the virtual reality (VR) headset
[0039] The base component 201 may use different interfaces to connect to different headsets. Examples are interfaces 401 and 801. The interface may also be built into the headset permanently.
[0040] The base component 201 has one or more mechanical attachment points 301 where the detachable component is connected. The mechanical attachment point may use a physical force, such as friction, in order to keep the detachable component in place, or it may include embedded magnets as is demonstrated in 701, or it may use another mechanical method not specifically outlined here.
[0041] FIG. 2 depicts detachable component 202. Detachable component 202 has one or more attachment points 204 where the detachable component connects to the base component. The mechanical attachment point may use a physical force, such as friction, in order to keep the detachable component in place, or it may include embedded magnets as is demonstrated in 901, or it may use another mechanical method not specifically outlined here.
[0042] The clinician can remove detachable component 202 and insert trial lenses into the trial lens slots 601 which are in the component There can be one or more slots for lenses. A clinician may insert one lens, or they may insert more than one lens, depending on the patient's vision
[0043] The virtual reality (VR) headset can be used with or without the detachable component 202. When detachable component 202 is not in use, the patient may use their own glasses or contacts in the headset. When detachable component 202 is used, the patient can look through loose trial lenses that are held in detachable component 202.
[0044] The foregoing description of various aspects of the invention has been presented for purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed, and obviously, many modifications and variations are possible. Such modifications and variations that may be apparent to a person skilled in the art are intended to be included within the scope of the invention as defined by the accompanying claims.
