Abstract

This paper proposes the use of a phase mask as an ophthalmic element to correct presbyopia in moderate cases and improve the visual acuity of people who suffer from it. Taking advantage of the main characteristic of the phase mask, which delivers a blur-invariant PSF in an axial range. The Neuronal Transfer Function (NTF) allows an improvement of the retinal images due to its behavior as a bandpass filter that increases the contrast of the degraded images. The simulations were carried out using two different mask profiles and pupil sizes of 2 mm, 4 mm, and 6 mm. To quantify the performance of the optical system, some metrics known as Visual Strehl are used, specifically VSOTF and VScombined.
