Home » Eye Strengthening Chart
Developed by the leading holistic research centre for colour and light from work by Rudolf Steiner and Johann Wolfgang von Goethe.
After extensive colour and light research on how to keep the human eye flexible and responsive, this valuable Eye-Strengthening Chart was developed by Hygeia Studios and its pioneer, the late Theophilus Heliodor Gimbel.
