Since the discoveries by American Ophthalmologist Dr. W. H. Bates, thousands of people have benefited by the best-selling book 'Better Eyesight without Glasses'. The eyeballs are shaped by muscles.

Light particles fall through the lens onto the retina.
137 million photoreceptors send the information via the optic nerves to the visual brain. It is in the visual cortex of the brain where we see. A stooped stance tends to contract the brain stem, contracts optic nerves, eye muscles, retina, the visual pathways and the visual cortex within the brain. The Alexander Technique, renowned for body ease and lightness, brings to our attention 'habits of misuse' and facilitates a new awareness to use our bodies more effectively. This is then followed by exercises of 'Vision Awareness' to establish 'good seeing habits'.
