Abstract
A contact lens charging case comprises a container sized and shaped to receive an electronic contact lens (“eCL”) and charging coil to couple to a coil of the eCL. In some embodiments, the charging coil comprises a diameter larger than a diameter of the coil of the eCL, so as to decrease sensitivity of the location and orientation of the eCL in the container and improve coupling between the coils. In some embodiments, the charging coil is dimensioned so as to extend at least partially around the container that receives the eCL.
Claims20
A charging case for an electronic contact lens (eCL), comprising:
- a housing;
- a power source within the housing;
- a container sized and shaped to receive the eCL;
- an aperture formed in the housing and shaped to receive the container therein;
- a charging coil coupled to the power source, the charging coil comprising a maximum cross-sectional dimension larger than a maximum cross-sectional dimension of a coil of the eCL;
- and
- a protrusion extending from the container and configured to couple the container to the housing while the charging coil charges the eCL.
