A liquid lens, a contact lens containing the liquid lens, and an intraocular device

Abstract

The group of inventions relates to the optical elements with variable characteristics, and specifically to the liquid lenses with variable optical power, and the contact lenses with enhanced functionality that are equipped with such liquid lenses. The liquid lens is implemented as a capsule containing control electrodes, immiscible first liquid medium having the refractive index n1 and second liquid medium having the refractive index n2, such that n2>n1. One of said liquid media is adapted to be controlled by the electromagnetic field via said electrodes. The second liquid medium represents a colloidal system formed by a liquid and solid high-refractive nanoparticles whose refractive index is higher than the refractive index of said liquid. The invention makes it possible to expand the possible application areas of such liquid lens by expanding the range of achievable optical power. The contact lens equipped with the above described liquid lens in the first embodiment enables the implementation of the zoom function, in the second embodiment when used with a microdisplay implements an AR/VR/XR mode, in the third embodiment when used with light emitting diodes implements a myopia prevention and treatment function. The intraocular device equipped with the above described liquid lens makes it possible to replace the user's crystalline lens and in addition has an enhanced functionality.
