(English) The first meditation is a progressive White Light relaxation through the body. Stress affects eyesight adversely, while relaxation is known to have a beneficial effect. The affirmations and visualizations which are presented at alpha are all intended for the improvement of your eyesight and vision.
Whatever you visualize repeatedly, you improve the probability of happening. Therefore, you can imagine what it will be like when your vision is clear again. Keep putting this picture of the future in your consciousness, and keep remembering the future as the means of creating it.
