1. An ophthalmic lens, comprising:
a first region corresponding to a first area of an optical surface of the ophthalmic lens; and
a second region corresponding to a second area of the optical surface of the ophthalmic lens different from the first area, the second region comprising an optically-switchable component switchable between a first optical state and a second optical state different from the first optical state, wherein in the first optical state the second region partially scatters or defocuses light incident on the second area,
wherein in the second optical state, the second region partially scatters light incident on the second area by an amount that is different than the first optical state.
