In the case of visual stress, such as is often the case with old head injuries or intensive computer work, the glasses can contribute to better performance.
In addition, the pinhole glasses provide a clearer view. Therefore, it is often used in combination with other vision exercises. The glasses can be worn 5-10 minutes before visual training for relaxation, but also in between in everyday life or actively in sports.
