The Retina’s "Yellow Spot": The Secret to Vision
The "Yellow Spot" is a part of the Retina that allows the details of whatever you’re
looking at to be seen more clearly.
The middle bit of the yellow spot is called the ‘Fovea Centralis’. This part of the
Yellow Spot ‘sees’ twice as well as the Retina itself, particularly in bright light.
When you focus on a small object or read a book, you see with this part of the
Retina.
Some of the exercises in this book, are specifically designed to help you retrain
your eyes to use the Fovea Centralis more effectively.
Peripheral vision: the ability to see out the corners of your eyes
In the normal eye peripheral vision is quite clear.
Peripheral vision is weakened by too much eye-squinting, close work and intensive
mental concentration for long periods. These activities center your eyes' attention
upon a single point only, and you begin to lose your ability to see peripherally.
According to the legendary Dr. Bates,
"The normal eye sees one thing best, but not
one thing only."
