Abstract
The invention provides methods for designing contact lenses in which method the lens flexure is taken into account. The method of the invention is insensitive to the lens' back surface design and does not require complex back surface designs. Additionally, the lens design can be optimized virtually, eliminating the need for iterative design-test on-eye-re-design cycles.
