Electrically-switchable contact lens with liquid crystal cell and diffractive element
A recently granted patent (Publication Number: US12001119B2) details an electrically-switchable flexible contact lens designed to conform to the user's eye. The lens includes a first liquid crystal cell with a diffractive optical element for vision correction, maintaining a specific cell gap thickness through support provided within the cell. The diffractive optical element's design ensures varying heights between the inner and outer portions, spacing the inner and outer surfaces of the cell differently to enhance performance.
Additionally, the contact lens may feature a perimeter spacer and a cholesteric liquid crystal for switching between refractive states. The patent outlines specific refractive index ratios between the liquid crystal and the diffractive optical element, as well as details regarding the attachment of the optical element to the inner surfaces. The design also includes a second liquid crystal cell for further focal power adjustment, with specific parameters for the diffractive optical element's height variation and extension over the lens surface. These innovative features aim to provide users with a customizable and adaptable contact lens solution for vision correction.
