Vision aid with sight improving perforated blind

摘要

The blind has several seeing holes arranged in a flat body which is impervious to light. Each seeing hole (1) has corners (3), which are formed as outward points, are rounded or built as double points. In the case of the double point the intermediate connection is inwardly arched or is formed as a point. The edges connecting the corners run so that the are inwardly arched to a central point (6) and/or have one or more points, which point inwardly. The distance (5) of the corners from a central point (6) is the same for all corners, or the distance for at least two corners is different.
