Abstract
A device includes a first lens configured to provide a first optical power that is variable within a first optical power adjustment range at a first step resolution. The device also includes a second lens coupled with the first lens and including a deformable member that is deformable to vary an optical power of the second lens. The second lens is configured to provide a second optical power that is variable within a second optical power adjustment range at a second step resolution, the second step resolution being smaller than the first step resolution.
