Abstract
A method for determining a three dimensional performance of an ophthalmic lens including: calculating a domain in which a condition between a local optical criterion and at a threshold value is fulfilled; determining the three dimensional performance of the ophthalmic lens according to the domain. A method of calculating an ophthalmic lens includes the method.
