Contact lens

A contact lens, comprising:

• a lens body including a cornea portion defining a central axis and a sclera portion that surrounds the cornea portion, wherein a connection boundary between the cornea portion and the sclera portion has an inner diameter within a range from 11.5 mm to 12.3 mm, and wherein the cornea portion defines a layout boundary spaced apart from the connection boundary by a distance that is within a range from 3.8 mm to 4.2 mm;
• and
• an embedded structure embedded in the lens body and arranged outside of the layout boundary, wherein the embedded structure includes a three-dimensional (3D) carrier having at least one oxygen permeable channel that has a central angle of 360 degrees with respect to the central axis;
• wherein, along a top-down direction parallel to the central axis, the layout boundary and the connection boundary jointly define an annular layout region therebetween, and at most 70% of an area of the annular layout region is shielded by the embedded structure.
