Summary:Electroactive dynamic lenses that have more than one degree of visual accommodation that supplements an accommodation provided by a human eye on which the electroactive dynamic lens is worn. The accommodation is provided via activation of a shape memory alloy structure through a transition. A desired change in a focal plane may be accomplished with structures that may be electroactively controlled to expand or contract during a transition of the shape memory alloy. In some embodiments, a ring containing one or more elements that expand or contract under the influence of an electrical current to modify an overall shape of a formable ophthalmic lens and accomplish visual accommodation.
