The eyes don't typically get sick on their own.

Neither do they heal themselves well in a sick body.

The retina has the highest oxygen demand of any tissue, requiring optimal respiratory and cardiovascular function.

The retina is embryologically part of the brain, and vision dominates brain functions in the neocortex, so the central nervous system must be functioning well.

Vision demands the finest voluntary control of skeletal muscles with only the extraocular muscles having a one to one relationship between controlling nerve axons and muscle cells.

Only vision demands a finely balanced coordination between this conscious neuromuscular control system and the two opposing divisions of the autonomic nervous system, with the parasympathetic division being responsible for accommodative focus for near vision.

The eyes are remarkably sensitive to stresses of all kinds, and depend on the immune system for both defense and detoxification.

Digestion and absorption of nutrients is as essential for healing as is the elimination of wastes and toxins.

Healing the eyes, especially in the face of 'irreversible' blinding eye disease, requires healing the whole organism, the whole person...
