Abstract:
A contact lens (100), containing a lens body (1), an electronic element (2) and a circuit structure (3). The lens body (1) contains an optical portion (11) and an annular wearing portion (12) surrounding the optical portion (11), wherein the annular wearing portion (12) has a C-shaped layout area (121) and a lower eyelid area (122) located between two ends of the layout area (121). The electronic element (2) is embedded in the lower eyelid area (122), and the circuit structure (3) is embedded in the annular wearing portion (12). The circuit structure (3) contains a carrier board (31) and a circuit (32), which is formed on the carrier board (31) and connected to the electronic element (2), wherein the carrier board (31) has a C-shaped section (311) embedded in the layout area (121), and the C-shaped section (311) is provided with at least one through hole (3111), the area of which occupies 1%-85% of the area enclosed by an outer contour of the C-shaped section (311). Therefore, by means of providing the at least one through hole (3111) in the contact lens (100), the wrinkles or stress concentration on the carrier board (31) is effectively reduced, and the oxygen permeability of the contact lens (100) is further improved.
