In this project we want to study how new light sources influence the quality of vision in situations with high demands on illumination. Modern light sources, such as LED, offers unique possibilities to control both light field, light spectrum and intensity while they are easy to integrate to avoid glare. This flexibility allows lighting systems with low power consumption and high quality of vision, but it is very important to take the characteristics and limitations of the human eye into account, so that glare is minimized and the visibility is maximized. We will carry out tests of the ocular performance of subjects in some common public places that we know are problematic for people with normal aging eyes or who have visual impairments. We will also perform photometric measurements and computer simulations of the same environments to understand which design parameters that are important for best functionality. The goal is to learn how to take advantage of the special features that LED lighting offers, to improve quality of vision for all people and for people with impaired vision in particular.
