Patent number: 11609437Abstract: Configuring ophthalmic lenses that reduce oblique aberrations based on a wearer's accommodative demand values is disclosed. The accommodative demand values include A_(rel?) and A_(rel+) depend on object vergence L. The accommodative demand values are considered to and ensure no or reduced eye strain to the wearer. An improved merit function ?? is calculated based on the accommodative demand values. In the calculation, accommodative term A is a smooth and continuous function of both the object distance L and the spherical component of the power error. This ensures the accommodative demand values are well below maximum relative accommodations available to the wearer to prevent eye fatigue. The calculation may also include a smooth and continuous thresholding function ƒ that optimizes the merit function.
