Abstract
Lenses and methods for adjusting the focus of a lens include dividing multiple light sensors in a lens into four quadrants. A position of the lens relative to occlusion along a top and bottom edge of the lens is determined based on numbers of bits in respective bit sequences from light sensors in respective regions of the lens. An optimal focal length for the lens is determined based on the position of the lens. The focal length of the lens is adjusted to match the optimal focal length.
