Understanding the Human Eye
The human eye is not just a mechanical tool for vision; it is one of the body’s most important body organs. The importance of the human eye is due to the following:
It gives perception and vision of the outside world. Eyesight is the most important of your five senses.
It is also connected to the inner world—your mind. Seeing is believing, and perception is reality. Your vision affects your perception, and hence your personality; it creates your own world.
It is inter-connected with different body organs, such as the brain (which controls how you see), the heart (which pumps blood and transports oxygen to your eyes), the liver (which supplies nutrients to the eye, according to Chinese medicine).
How the Eye Functions
Simply put, you cannot see without light.
When you see an object, the light from that object passes through the lens (in front of the eyeball), which is held in place by ciliary muscles in your eye.
The lens then focuses the image on the retina (at the back of the eyeball), which sends the visual information through the optic nerve to the brain.
The human lens is designed for distant vision, not close vision. When the object is too close (i.e. less than 20 feet away), the ciliary muscles must contract in order to focus the visual image correctly on the retina. This process of contraction or expansion of the eye muscles is known as accommodation.
AWARENESS Consciously train your eyes for distant vision! Regularly look up from your computer or your book!
How the Eye Malfunctions
Poor vision is a result of the malfunctioning of the human eye, causing all types of vision problems.
When the ciliary muscles (eye muscles in the eye's middle layer that control accommodation for viewing objects at varying distances) are too weak to contract properly, the focal image of a distant object may fall in front of the retina (i.e. when the eyeball is too long), instead of directly on the retina itself, and hence it creates a blurred image. This happens in nearsightedness.
When the ciliary muscles are too weak to contract properly, the focal image of a close object may fall beyond the retina (i.e. when the eyeball is too short), the resulting visual image becomes blurry and distorted. This happens in farsightedness.
Therefore, the key to vision self-healing is to address these two critical issues.
AWARENESS: The shape of the eyeball determines the power of vision. The relaxation level of the eye pre-determines the shape of the eyeball.
