Wavefront coding (WFC) enables the depth of field of incoherent optical systems to be extended. This method involves a cubic-phase plate in the system yielding a blurred image nearly invariant to defocus. In visual optics there is a big interest in improving solutions for two different problems: Presbyopia correction and high resolution retinal images with low cost devices. In this work we will show how the use of cubic phases in contact lenses can be an alternative to multifocal lenses and how WFC technique can be applied to record high resolution retinal images reducing the complexity of the actual systems
