“…A partir de estas pruebas, fueron clasificados como sujetos experimentados y seleccionados para el experimento. Esta metodología de trabajar con un grupo reducido pero experimentado ha sido validada en algunos trabajos de deslumbramiento (21,22). Cabe mencionar que los 7 sujetos fueron medidos cada media hora en dos períodos estacionales obteniéndose un total de 56 condiciones lumínicas.…”

Para lograr los beneficios de iluminar con luz natural espacios de trabajo, hay que evitar que la luz natural sea bloqueada por el potencial riesgo de deslumbramiento. Para lograr una adecuada caracterización del mismo es importante considerar la percepción del tiempo de exposición de la fuente en el campo de visión (Aspecto no incluido en los modelos de deslumbramiento). Para determinar de qué manera influye este aspecto perceptual en la sensación de deslumbramiento se evaluaron dos escenarios con dos tipos de manchas solares sobre el puesto de trabajo: 1) Con mayor profundidad de ingreso y más tiempo en el campo de visión, 2) Con menor profundidad de ingreso y menos tiempo en el campo de visión. Se midieron parámetros subjetivos (GSV) y variables fotométricas (DGP, EV y CL). Siendo la principal variable explicativa la EV (rho=0.51). Observándose también una mayor tolerancia al deslumbramiento por el efecto transitorio de la fuente.

“…However, a recent study made under daylight conditions showed that the ratio between the mean luminance of the task and the average luminance of the glare source showed the best correlation with subjective response. This study recommends a ratio from 0 to 22.0 for achieving an imperceptible glare zone [22]. argue that existing glare methods do not specify the cause of a glare issue; these methods only specify the levels of visual discomfort [23].…”

“…The first independent variable introduced into Model 1 was "Ls_min", which represents the absolute glare factor, and the second independent variable introduced was "Ls_mean/Lt_mean", which represents the relative glare factor. This first model includes the variables proposed by Suk et al [22] and both variables showed an acceptable R 2 -values. Furthermore, the first independent variable introduced into Model 2…”

“…An absolute glare factor was introduced into the two models as the main independent variable, and a relative glare factor as the second independent variable. While both variables are involved in every glare condition, absolute glare factors are more dominant than relative glare factors [22]. The following regression equation 3was obtained from the multiple regression analysis (model 2).…”

The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. Highlights  A new equation was proposed for evaluating glare in offices with direct sunlight  Absolute and relative glare values were evaluated in real working conditions  Percentage of central and near FOV over 2000cd/m2 was tested as absolute glare factor
