The stabilized contact lens methods and apparatus disclosed herein provide improved stabilization of a contact lens placed on a cornea of an eye. The contact lens comprises stabilization zones that allow the lens to repeatedly and consistently orient on the cornea such that a sensing zone located on the lower portion of the lens is located inferiorly to engage the lower eyelid. The stabilized contact lens can provide a lower pressure sensing zone with decreased thickness for pressure or other sensing related to the lower eyelid. The decreased thickness has the advantage of improving coupling between forces from an eyelid and a lower chamber of a fluidic module. The improved coupling allows increased amounts of fluid to move between the lower chamber and an upper optical chamber coupled to the lower chamber, such that the upper chamber can increase curvature and optical power in response to pressures of the eyelid.

Accommodating ophthalmic devices including an ambient light sensor and an accommodation sensor and related methods of use are described. In an example, the accommodation sensor is configured to measure a biological accommodation signal of an eye on or in which the accommodating ophthalmic device is mounted. In an embodiment, the accommodating ophthalmic device is configured to measure the biological accommodation signals based on ambient light, such as based on an intensity or amount of ambient light, incident on the accommodating ophthalmic device. Such ambient light may be measured with the ambient light sensor.

A wearable training apparatus has a vision-control assembly and a head-mounting assembly coupled to the vision-control assembly. The vision-control assembly has a see-through area corresponding to a central portion of the human field of vision (FOV), and a vision-blocking area for blocking the human peripheral FOV except the central portion thereof. The wearable training apparatus may be in the form of a pair of eyeglasses with lenses provided with reduced FOV or alternatively, may be in the form of a goggle with reduced FOV. A training system may comprise one or more wearable training apparatus, one or more imaging devices for recording images and/or video streams of the performance of users wearing the training apparatuses, and one or more computing devices for playing back and analyzing the recorded images and/or video streams.

Ophthalmic devices and ophthalmic systems including alignment sidewalls and blend zones disposed therethrough are described. An example ophthalmic device may include a first and a second optical element having alignment sidewalls shaped to cooperatively couple. The alignment sidewall may include blend zones disposed in the sidewall shaped to transition the sidewall from a ridge to a surface of an optic zone of the optical element. The alignment sidewalls may define a cavity disposed between two coupled optical elements when the alignment sidewalls are cooperatively coupled into which a liquid crystal may be disposed. A method of assembling an ophthalmic device is described. An example method may include aligning a blend zone of a first optical element with a mating blend zone of a second optical element. The example method may further include cooperatively coupling alignment sidewalls of the first optical element and the second optical element.

A focus adjusting tool used to perform an initial setting for a pair of autofocus eyeglasses includes an adjusting lens that refracts reflected light from a visual object, a housing including an inner space that allows a parallel movement of the adjusting lens, an adjusting unit that adjusts a position of the adjusting lens inside the housing, and a first end and a second end in a moving direction of the adjusting lens. The first end is provided with a hole for visually observing a visual object through a power variable lens of the pair of autofocus eyeglasses. The adjusting lens adjusts, in response to the position thereof inside the housing, an incident angle of the reflected light from the visual object into the power variable lens, the visual object being located on the side of the second end.

The present technology provides a display device that is able to display information in a region larger than a visual field region and cause the information to be visually recognized. The display device according to the present technology includes a light irradiation system configured to apply light through a pupil on at least a region outside an ambient light irradiation region, within a larger region than the ambient light irradiation region, the larger region including the ambient light irradiation region, the ambient light irradiation region being a region in a retina on which ambient light is to be applied through the pupil.

A flexible optical element adopting liquid crystals (LCs) as the materials for realizing electrically tunable optics is foldable. A method for manufacturing the flexible element includes patterned photo-polymerization. The LC optics can include a pair of LC layers with orthogonally aligned LC directors for polarizer-free properties, flexible polymeric alignment layers, flexible substrates, and a module for controlling the electric field. The lens power of the LC optics can be changed by controlling the distribution of electric field across the optical zone. Lens power control can be provided using combinations of electrode configurations, drive signals and anchoring strengths in the alignment layers.
