Benefits of technology

The present disclosed technology allows for direct measurements of the distance between objects by using special lenses that can measure their own alignment with respect to another object. This eliminates the need for complicated and expensive equipment like eyesight devices. Additionally, it provides enough space to make things look better at longer ranges than traditional methods.

Problems solved by technology

The technical problem addressed by this patent is how to improve the method, system, and componentry of determining a proper focus point for an electro-lens system without requiring excessive energy consumption and complexity.

Embodiment Construction

[0026]Exemplary embodiments described below relate to a method and system for determining a correct focus point for an electro-active accommodating lens system based on convergence sensing via magnetic fields, and automatically focusing the electro-active lens. Although many of the examples herein focus on IOLs, it is understood that the principles and techniques apply analogously to automatic-focusing contact lenses.

[0027]The following description is presented to enable one of ordinary skill in the art to make and use the invention and is provided in the context of a patent application and its requirements. Various modifications to the exemplary embodiments and the generic principles and features described herein will be readily apparent. The exemplary embodiments are mainly described in terms of particular methods and systems provided in particular implementation, though the methods and systems will operate effectively in other implementations. Phrases such as “exemplary embodiment,”

Abstract

A lens system comprises a first electro-active lens comprising a first focus sensor coupled to a first processor and a second electro-active lens comprising a second focus sensor coupled to a second processor. The first focus sensor periodically generates electromagnetic signals and detects electectromagnetic signals generated by the second focus sensor. The second focus sensor periodically generates electromagnetic signals and detects electectromagnetic signals generated by the second focus sensor. The first processor receives an indication of the second electromagnetic signals and, based on the received indication of the second electromagnetic signals, determines a relative convergence angle between the first and second electro-active lenses. Based on the determined relative convergence angle, the first processor determines a focal setting for the first electro-active lens and controls an electroactive element in the first electro-active lens, based on the determined focal setting.
