It is well known that the vision of vehicle drivers is influenced by scattered light caused by damaged windshields. This is particularly produced during the night, at sunrise and sunset. This scattered light depends on various factors such as inclination angle, intensity of the light source and surface state of the windshields. The objective of this work is to study the influence of the angle of illumination on light scattering by sandblasted soda-lime-silica glass. Firstly, the effect of the angle of illumination and the projected sand mass on light scattering is studied. The results show that the number of created defects increases with the projected sand mass until a saturation state is reached at 50g under the chosen test conditions. In this case, the specular transmission decreases and reaches a constant value of about 18% showing the importance of scattered light. At the same time, the angle of illumination affects the optical transmission and therefore the light scattering. For an angle of de c and as and mass of 50g, for example, the specular transmission decreases to about 59%. Secondly, two parameters (the angle of illumination and the projected sand mass) were combined to distinguish between the transparent domain and the blurred one.
