Abstract
An ophthalmic lens includes 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 has an optically-switchable component switchable between a first optical state and a second optical state different from the first optical state. In the first optical state the second region partially scatters or defocuses light incident on the second area.
