Descripción
The degree of eye opening (DEO) is proposed as a new indicator of glare in sunny climates in the presence of direct sunlight. A laboratory experiment was carried out (. n=20) in a simulated office space where volunteers performed computer office tasks. Four lighting situations, based on ranges of vertical illuminance at the eye level were evaluated. By means of a visible spectrum eye-tracker DEO was registered in each scenario. The proposed indicator was obtained by mathematical iterations and showed a good correlation with: vertical illuminance at the eye (. r=-0.503; α=0.0001), Daylight Glare Probability (DGP) (. r=-0.649; α=0.0001) and Glare Sensation Vote (GSV) (. r=-0.580; α=0.0001). This new indicator operates in a broad range of lighting conditions, from a low vertical illuminance at the eye scenario with diffuse daylight to a very high vertical illuminance at the eye scenario with uncontrolled direct sunlight. The proposed new indicator satisfies the following criteria: high validity, reliability, diagnostic power and acceptability and it also addresses unresolved aspects of current glare predictive models: GSV, DGP and DGI.
