A contact lens system for placing in an eye comprising:
- a display comprising a matrix of display elements;
- a driver unit configured to receive data from a host and to present the data on the display;
- a set of sensors integrated on the display for measuring pupil size;
- and wherein
- the driver unit is further configured to read outputs from the set of sensors to determine the pupil size and adjust a size of an active area of the display based on the pupil size by activating and deactivating the display elements.
A method for adjusting a size of an active area of a display in a contact lens system placed in an eye, wherein the display comprises a matrix of display elements, the method comprising:
- reading outputs from a set of sensors integrated on the display;
