Abstract
A dazzle protection unit (1) for a portable dazzle protection device that includes an optical dazzle protection filter (3) and at least one sensor (5) for the sensing of incident light and for controlling the translucency of the filter (3). In doing so, the dazzle protection unit (1) includes a light capturing element (4), which captures incident light on a light capturing surface area (12) and conducts it to the at least one sensor (5). The light capturing element (4) preferably captures the light from several areas located at a distance from one another on a front side of the dazzle protection unit (1). Means (8) for coupling light into the light capturing element (4) are situated at a distance from one another.
