A contact lens according to an embodiment of the present disclosure includes a lens section attachable to an eyeball, and one or a plurality of structure portions provided in the lens section and intended to accumulate tears. This makes it possible to, for example, measure an absorption spectrum of the tears, by emitting light toward the tears accumulated in the one or plurality of structure portions.

The disclosure provides for an apparatus for intraocular lens selection. The apparatus may include a biometer and an autorefractor. The biometer may be configured to obtain at least two ocular measurement parameters for an eye. The autorefractor may be configured to obtain a post-operative refraction of the eye. The apparatus may also include a user interface configured to obtain a lens selection parameter for the eye, a memory, and a processor communicatively coupled to the biometer, the user interface, the autorefractor, and the memory. The processor may be configured to determine an intraocular lens power based on a formula using the at least two ocular measurement parameters. The processor may be configured to correlate the at least two ocular measurement parameters, the intraocular lens power, and the post-operative refraction as a training set.

A method includes: determining, by a computing device, historic eye data of a user; determining, by the computing device, a current eye condition of the user based on: current data from a photodiode sensor of a smart contact lens worn by the user; current data from an image sensor of the smart contact lens worn by the user; and the historic eye data of the user; and adjusting, by the computing device, a transmittance of the smart contact lens worn by the user based on the determined current eye condition.

System and method directed towards providing full and even illumination of a patient's retina through lighting integrated into a handheld fundus lens. By integrating the lighting, the method and system reduces and even eliminate many lens artifacts and reflections. By increasing the accuracy, quality, and field of view afforded during clinical examination of the retina, the method and system will allow practitioners to make more accurate diagnoses and will increase safety during retinal surgical procedures.

Embodiments of the present invention are directed to a method of stimulating a cornea. A non-limiting example of the method includes capturing a sound with a microphone. A non-limiting example of the method also includes transducing the sound to an electric signal by a microprocessor. A non-limiting example of the method also includes stimulating a piezo-electric element adjacent to a receptor of the cornea, wherein the piezo-electric element is positioned on an eye lens with an electric signal. A non-limiting example of the method also includes mechanically stimulating a receptor of the cornea with the stimulated piezo-electric element.

The present disclosure relates to calibration, customization, and improved user experiences for smart or bionic lenses that are worn by a user. The calibration techniques include detecting and correcting distortion of a display of the bionic lenses, as well as distortion due to characteristics of the lens or eyes of the user. The customization techniques include utilizing the bionic lenses to detect eye characteristics that can be used to improve insertion of the bionic lenses, track health over time, and provide user alerts. The user experiences include interactive environments and animation techniques that are improved via the bionic lenses.
