A larger GP lens tends to position the lens higher on the cornea.

Explanation:
When a GP lens is larger, it covers more of the sclera and engages more with the surrounding lid tissue. That increased lid contact, especially with the upper lid, tends to position the lens higher on the ocular surface. The larger sagittal height and greater lid influence push the center of the lens toward the superior part of the cornea, so the optical zone sits higher rather than lower. In short, bigger diameter means more lid-driven support and a higher resting position on the cornea.
