Abstract:
A contact lens, comprising a lens body (1) and an embedded module (10). The lens body (1) comprises an optical portion (11) and an annular wearing portion (12) surrounding the optical portion (11). The embedded module (10) comprises a preform (4) made of an eye-friendly material and a circuit structure (3) embedded in the preform (4). The preform (4) is completely embedded in the annular wearing portion (12) of the lens body (1), and the preform (4) is in the form of a ring and surrounds an outer side of the optical portion (11). The preform (4) and the lens body (1) are connected to each other without a gap to form an engagement interface (43) which is configured to be spaced apart from a rear surface (1b) and a front surface (1a) of the lens body (1). A partial surface of the circuit structure (3) is flush with a surface of the preform (4), and is engaged to the annular wearing portion (12). Thus, the circuit structure (3) can be embedded and positioned in the preform (4) in advance, so as to facilitate completely embedding and positioning the circuit structure (3) in the lens body (1).
