Devices and methods utilizing novel intraocular lens (IOL) designs are discussed herein. One aspect relates to IOLs having an optic with non-uniform light transmissivity. For example, the optic of the IOL can include a central region having a reduced light transmissivity relative to another portion of the optic. In addition, or alternatively, the optic can have a peripheral region having reduced light transmissivity. Such IOLs can potentially be utilized to alter the light distribution impinging on a subject's retina, which can be tailored to specific lighting situations such as bright and dim light conditions. Such IOLs can also, or alternatively, be used to help alleviate the perception of dark shadows known as negative dysphotopsia. Other aspects and features of IOLs, and methods, are also discussed.
