Including Apple’s own Vision Pro headset, one of the pain points of the current mainstream AR/VR headsets is that they are not friendly to vision correction users.
These users either wear glasses and cannot get a comfortable experience for a long time; or custom-made special glasses clips (usually at an additional cost), and the experience is not comfortable enough.
Apple recently filed an application titled “Electronic Device with Liquid Lens,” outlining a possible future headset design.
It is learned from the patent that the lenses in the head-mounted display device use adjustable liquid lenses, each lens can have a lens chamber filled with liquid, and the lens chamber can have rigid and/or flexible walls that form the surface of the optical lens.
A system of actuators, pumps, and reservoirs can alter the lens surface to adjust the refractive index in response to a control circuit signal.
If Apple applies this patent to the future Vision Pro headset, the liquid lens will dynamically adjust the focal length and refractive index according to the wearer’s situation, providing a more comfortable wearing experience.
Apple also describes the future Vision Pro design in the patent: if desired, the head-mounted display device can be polished into a pair of regular glasses, equipped with left and right temples, nose bridge, lens frame, etc., configured as a glasses frame.
