Perceptually Calibrated Scale of Optical Aberrations

Plain-language summary

The main objective of the project is to develop a new, more reliable method of modeling and parametrization of the halo and glare phenomena based on the subjective perception of these visual disturbances. The project will consist of three parts. The first will include the psychophysical measurement of glare and halo phenomena perceived by people with multifocal corrective lenses compared to the reference group. The second part will focus on the development of an algorithm for the generation of optical elements (masks) inducing standard halo and glow effects of a given size and intensity. The third phase of the project will concern the calibration of the developed algorithm. For this purpose, the halo and glare will be induced by the developed masks in the healthy eye, so as to match them with the vision disorders measured in the first part of the project in people using multifocal vision correction methods. As a result of this research, a scale for precise measurement of subjective halo and glare phenomena in the field of view will be created, independently covering their intensity and size, and in the future allowing for optical (and not graphic simulation as in commercially available simulators) simulation of scenes seen by patients.
