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.
