Described are multifocal contact lenses that contain high energy visible (HEV) light absorbing compounds and their use for improving one or more vision attributes.

Multifocal contact lens displaying improved vision attributes

A family of ophthalmic lenses for correcting presbyopia meets constraints for distance vision, near vision, and disparity and may be designed according to a process that incorporates a merit function accounting for binocular visual performance.

Lens systems for presbyopia

The invention provides methods for designing contact lenses and contact lenses designed according to the method, which lenses provide an improved method for presbyopia correction compared to conventional lenses and methods. It is a discovery of the invention that improved performance and reduced design time can be obtained by using lens pairs that act synergistically to provide the lens wearer with good binocularity and consistent performance in near, intermediate and distance vision.
