Abstract
Methods for ophthalmic lens design incorporating a visual acuity profile are disclosed. The methods include applying rules and functions to visual acuity profile data and an ophthalmic prescription to generate ophthalmic lens parameters for a subject. The visual acuity profile data includes a maximum visual acuity for the subject. The visual acuity profile data may also include a focus tolerance or tolerable blur. Tolerable blur may be measured by an ophthalmic professional or extrapolated. The visual acuity profile data may also include eye physical data such as pupil diameter and eye size, accommodation, retinal photoreceptor cell packing information and neural processing information. The visual acuity profile data may also include personal biographic and/or medical information for the subject.
