CENTRAL FIXATION IS A CORRECT VISION HABIT, (THE NORMAL FUNCTION OF THE EYES) THAT PRODUCES VERY CLEAR EYESIGHT.
CENTRAL FIXATION = TO SEE CLEAR BY USING THE CENTER OF THE VISUAL FIELD.
TO PLACE THE OBJECT THE EYES ARE LOOKING AT IN THE CENTER OF THE VISUAL FIELD.
THE CENTER OF THE VISUAL FIELD IS BETWEEN THE EYES, AT EYE LEVEL.
THE CENTER IS THE CLEAREST AREA OF THE VISUAL FIELD, CLEARER THAN 20/20.
IN THE DIAGRAM ABOVE THE GIRL IS LOOKING AT THE BLUEBIRD IN THE TREE.
THE BIRD IS IN THE CENTER OF THE VISUAL FIELD AND IS SEEN CLEAR.
RELAXATION, SHIFTING AND CENTRAL FIXATION ARE THE 3 MAIN CORRECT VISION HABITS THAT KEEP THE EYESIGHT CLEAR.
AVOID STARING, EYE IMMOBILITY AND BECOMING STIFF, IMMOBILE WHEN PLACING A OBJECT IN THE CENTER OF THE VISUAL FIELD. 
RELAX AND MOVE.
                                                                                                                                    

                   


CENTRAL FIXATION IS COMBINED WITH SHIFTING = SHIFT/MOVE THE EYES FROM PART TO PART ON THE OBJECT.
THE EYES, HEAD/FACE, NECK AND BODY ARE RELAXED AND MOVE FREELY.
BLINK, RELAX AND MOVE.
EVEN A SMALL MOVEMENT OF THE HEAD/FACE, NECK AND BODY WHEN SHIFTING ON A OBJECT KEEPS THE BODY, NECK, EYES RELAXED AND EYESIGHT CLEAR.

THE SMALL PART OF THE OBJECT THE EYES ARE LOOKING AT IS IN THE EXACT CENTER OF THE VISUAL FIELD.
EXAMPLE; PRACTICE SHIFTING FROM PART TO PART (DOT TO DOT) ON THE BLUE BIRD.
SHIFT TOP AND BOTTOM, LEFT AND RIGHT, MIDDLE AND FROM SMALL PART TO SMALL PART ON ANY AREA OF THE BIRD.
AS THE EYES SHIFT FROM ONE SMALL PART TO ANOTHER SMALL PART ON THE BIRD, THE EXACT CENTER OF THE VISUAL FIELD MOVES WITH THE EYES FROM PART TO PART KEEPING EACH PART PERFECTLY CLEAR.
MOVE THE HEAD/FACE AND BODY WITH THE EYES EVEN WHEN SHIFTING ON A VERY SMALL OBJECT.
RELAX AND MOVE THE NECK.

THE EXACT CENTER OF THE VISUAL FIELD IS VERY SMALL, ABOUT THE SIZE OF THE POINTED END OF A PIN.
THIS SMALL AREA IS THE MOST PERFECT, CLEAREST AREA OF THE VISUAL FIELD AND IS PRODUCED BY THE FOVEA CENTRALIS AND ITS MANY CONES IN THE MACULA IN THE EXACT CENTER OF THE EYES RETINA. THE FOVEA PRODUCES VERY CLEAR, FINE DETAILED EYESIGHT, CLEARER THAN 20/20;  20/10, 15, 5 AND CLEARER WITH BRIGHT COLOR PERCEPTION.
THIS IS WHY DR. BATES TEACHES HIS STUDENTS TO SHIFT FROM SMALL POINT TO SMALL POINT ON A OBJECT; TO SEE CLEAR WITH THE CENTER OF THE VISUAL FIELD, CENTRAL FIXATION; TO MOVE THE SMALL EXACT CENTER OF THE VISUAL  FIELD FROM SMALL PART TO SMALL PART; POINT TO POINT ON A OBJECT FOR VERY CLEAR VISION.
SEEING WITH THE CENTER OF THE VISUAL FIELD RELAXES THE MIND AND EYES.
WHEN THE MIND RELAXES THE EYES RELAX AND EYESIGHT IS CLEAR.

THE MACULA SURROUNDING THE FOVEA AND AREAS OF THE RETINA CLOSE TO THE MACULA IN THE CENTER OF THE RETINA ALSO CONTAIN MANY CONES AND PRODUCE VERY CLEAR VISION IN THE CENTER OF THE VISUAL FIELD BUT THE FOVEA IN THE EXACT CENTER OF THE RETINA PRODUCES THE TINY EXACT CENTER OF THE VISUAL FIELD AND CLEAREST VISION.
USING THE EXACT CENTER OF THE VISUAL FIELD ACTIVATES PERFECT CENTRAL FIXATION, CLEARER THAN 20/20 CENTRAL VISION AND MAXIMUM CLARITY OF PERIPHERAL VISION.  CLARITY OF THE ENTIRE VISUAL FIELD IMPROVES.
WHEN THE EYES SEE CLEAR WITH THE CENTER OF THE VISUAL FIELD, THE CENTRAL LIGHT RAY FOCUSES EXACTLY ON THE FOVEA CENTRALIS IN THE CENTER OF THE MACULA, RETINA.
THE PERIPHERAL RAYS FOCUS PERFECT ONTO THE PERIPHERAL AREA OF THE RETINA.
CENTRAL VISION IS CLEARER THAN 20/20 AND PERIPHERAL VISION IS LESS CLEAR THAN CENTRAL VISION, AT ITS MAXIMUM CLARITY.
SHIFTING ON SMALL OBJECTS, SMALL PARTS OF OBJECTS AT CLOSE AND FAR DISTANCES WITH THE EXACT CENTER OF THE VISUAL FIELD RESULTS IN VERY CLEAR EYESIGHT.
SMALL DETAILS OF OBJECTS ARE SEEN CLEAR AT ALL DISTANCES.

PRACTICE SHIFTING ON THE TINY CRATER'S ON THE MOON FOR CLEAR DISTANT EYESIGHT AND ON SMALL DETAILS ON A PIECE OF JEWELRY FOR CLEAR CLOSE EYESIGHT.
BLINK AND RELAX.
WHEN THE EYES SHIFT TO A DIFFERENT OBJECT, THE CENTER OF THE VISUAL FIELD MOVES WITH THE EYES TO THE NEW OBJECT.
THE HEAD/FACE AND BODY MOVE WITH THE EYES AT THE SAME TIME, IN THE SAME DIRECTION.
THIS KEEPS THE OBJECT THE EYES ARE LOOKING AT IN THE CENTER OF THE VISUAL FIELD.

WHEN THE EYESIGHT IS UNCLEAR, SOME PEOPLE DEVELOP THE INCORRECT VISION HABIT OF TRYING TO SEE WITH THE PERIPHERAL FIELD OF VISION.
PERSONS WITH CATARACTS, MACULA DEGENERATION OFTEN USE THIS INCORRECT HABIT.
TRYING TO SEE A OBJECT CLEAR  BY PLACING IT IN THE PERIPHERAL FIELD STRAINS, TENSES THE EYES, EYE MUSCLES, RETINA AND CAUSES, INCREASES BLUR, ASTIGMATISM, CATARACTS, MACULA DEGENERATION AND OTHER EYE PROBLEMS.

THE CENTRAL LIGHT RAY MUST FOCUS ON THE FOVEA CENTRALIS IN THE MACULA, CENTER OF THE RETINA (NOT THE PERIPHERAL) TO PRODUCE CLEAR EYESIGHT.
CENTRAL FIXATION; PLACING THE PART OF THE OBJECT THE EYES ARE LOOKING AT IN THE EXACT CENTER OF THE VISUAL FIELD, KEEPS THE CENTRAL LIGHT RAY ON THE FOVEA CENTRALIS RESULTING IN CLEAR CENTRAL VISION AND PERFECT FOCUS OF PERIPHERAL LIGHT RAYS ON THE PERIPHERAL AREA OF THE RETINA FOR MAXIMUM CLARITY OF CENTRAL AND PERIPHERAL VISION.
SEEING WITH CENTRAL FIXATION, THE CENTER OF THE VISUAL FIELD REVERSES AND PREVENTS UNCLEAR EYESIGHT, ASTIGMATISM, CATARACTS, MACULA DEGENERATION, CROSSED, WANDERING EYES AND OTHER EYE PROBLEMS RESULTING IN HEALTHY EYES AND CLEAR EYESIGHT.

OPHTHALMOLOGIST BATES TAUGHT, THAT WHEN LOOKING AT A OBJECT; ONE SMALL PART IS SEEN CLEAREST AT A TIME.  THE CENTER OF THE VISUAL FIELD IS CLEAREST AND THE PERIPHERAL IS LESS CLEAR.
THIS IS NORMAL.
THIS IS CENTRAL FIXATION.
EXAMPLE; LOOK AT THE APPLE.
TRYING TO SEE THE ENTIRE APPLE (PARTS IN THE CENTRAL AND PERIPHERAL FIELD) PERFECTLY CLEAR AT THE SAME TIME CAUSES STRAIN AND BLUR.
THE EYES RELAX AND THE APPLE IS SEEN CLEAR BY SEEING ONE SMALL PART OF THE APPLE CLEAREST AT A TIME IN THE CENTER OF THE VISUAL FIELD AND SHIFTING CONTINUALLY, EASILY FROM PART TO PART. 
EXAMPLE; LOOK AT/SEE THE DOT ON THE LEFT CLEAREST, THEN LOOK AT/SEE THE DOT ON THE RIGHT CLEAREST, THEN THE DOT ON THE TOP, THEN BOTTOM, THEN MIDDLE.
THE CENTER OF THE VISUAL FIELD MOVES WITH THE EYES FROM DOT TO DOT, KEEPING EACH DOT (PART) THE EYES LOOK AT CLEAR. THE APPLE IS SEEN CLEAR.
 
STARING; EYE IMMOBILITY CAUSES UNCLEAR EYESIGHT;
+EXAMPLE; STARE AT ONE SMALL PART OF THE APPLE  (ONE DOT) WITHOUT MOVING THE EYES TO ANOTHER PART. 
KEEP THE EYES IMMOBILE, LOOKING AT ONLY ONE PART.
IN A SECOND OR TWO, EYESTRAIN IS FELT AND THE CLARITY OF EYESIGHT LOWERS.
+TRYING TO SEE THE ENTIRE OBJECT ALL PARTS, CENTRAL AND PERIPHERAL FIELD CLEAR WITHOUT MOVING THE EYES FROM PART TO PART ALSO CAUSES STRAIN AND BLUR.
 -TRYING HARD TO SEE CLEAR CAUSES STRAIN AND BLUR.
 -RELAXATION AND MOVEMENT (NO EFFORT TO SEE) BRINGS CLEAR EYESIGHT.
THE EYES RELAX AND EYESIGHT IS CLEAR WHEN THE EYES APPLY SHIFTING WITH CENTRAL FIXATION; SEE ONE SMALL PART CLEAREST AT A TIME IN THE CENTER OF THE VISUAL FIELD AND MOVE THE EYES BY SHIFTING CONTINUALLY, SLOWLY, RELAXED FROM ONE SMALL PART TO ANOTHER.
THIS IS THE NORMAL FUNCTION OF THE EYES.
AS SLOW, CONTINUAL SHIFTING IS PRACTICED, FASTER SHIFTING OCCURS SUBCONSCIOUSLY, A AUTOMATIC EYE FUNCTION.
SEE SACCADIC , MICROSCOPIC AND OTHER EYE MOVEMENTS DESCRIBED BELOW AND IN CHAPTER 8.
THE EYES CAN SHIFT SO FAST WITH THE CENTER OF THE VISUAL FIELD MOVING QUICKLY FROM SMALL PART TO SMALL PART THAT THE ENTIRE OBJECT APPEARS CLEAR.
IN REALITY, ONLY ONE SMALL PART IS SEEN CLEAR AT A TIME AS THE CENTER OF THE VISUAL FIELD PASSES OVER THAT PART.
THE CENTER OF THE VISUAL FIELD MAY BE ON A PART FOR ONLY A FRACTION OF A SECOND.  DURING THAT FRACTION OF A SECOND, THE PART IS IN THE CENTER OF THE VISUAL FIELD AND IS SEEN CLEAREST. 

PRACTICE SHIFTING AND CENTRAL FIXATION AND THE EYES AND BRAIN WILL ACTIVATE THESE CORRECT VISION HABITS/FUNCTIONS AND CLEAR EYESIGHT AUTOMATICALLY.

THE EYE, BRAIN PRODUCES MANY DIFFERENT TYPES OF EYE MOVEMENTS; LARGER/LONGER  MOVEMENTS AS THE EYES SHIFT FROM OBJECT TO OBJECT AND PART TO PART ON A OBJECTS, SMALLER MOVEMENTS WHEN SHIFTING ON SMALLER OBJECTS, SMALL PARTS OF OBJECTS, SACCADIC SHIFTS, HIGH FREQUENCY VIBRATIONS, OPTICAL DRIFT, NATURAL TREMORS, SMALL, TINY, MICROSCOPIC AND OTHER MOVEMENTS.
THESE MOVEMENTS COMBINE, INTEGRATE TOGETHER AND PRODUCE HUNDREDS, THOUSANDS OF EYE MOVEMENTS PER SECOND.
THESE MOVEMENTS KEEP THE EYE MUSCLES RELAXED AND VISION VERY CLEAR, CLEARER THAN 20/20.
THIS IS THE NORMAL OPTIMUM FUNCTION OF THE EYE.
ALL EYE MOVEMENTS ARE SUBCONSCIOUS, AUTOMATIC. JUST AS THE HEART BEATS AND OTHER BODY ORGANS FUNCTION ON THEIR OWN, AUTOMATICALLY, THE EYE MOVES AUTOMATICALLY. EYE MOVEMENT OCCURS LIKE A AUTOMATIC HABIT; SHIFTING, A CORRECT VISION HABIT.

WHEN VISION IS UNCLEAR AND THE EYE MUSCLES ARE TENSE, ALL EYE MOVEMENTS ARE REDUCED, IMPERFECT, RIGID, TOO SLOW.
THIS CAUSES UNCLEAR VISION.
WHEN THE EYES MOVE CONTINUALLY, FREQUENTLY, EASY, VISION IS CLEAR.
WATCH A PERSON THAT HAS CLEAR EYESIGHT. NOTICE THEIR CORRECT EYE MOVEMENT; WHEN LOOKING AT DISTANT OR CLOSE OBJECTS THE EYES MOVE, SHIFT CONTINUALLY FROM OBJECT TO OBJECT, PART TO PART, SMALL POINT TO SMALL POINT ON OBJECTS.
PRACTICING SHIFTING, RELAXATION, CENTRAL FIXATION AND ALL CORRECT VISION HABITS RETURNS ALL EYE MOVEMENTS TO NORMAL, RESULTING IN EYE MUSCLE RELAXATION AND CLEAR EYESIGHT.
THE BRAIN ACTIVATES ALL EYE MOVEMENTS.
RELAXATION OF THE MIND/BRAIN IMPROVES FUNCTION OF THE BRAIN,  ACTIVATES NORMAL EYE MOVEMENTS AND CLEAR EYESIGHT.

I LIKE THE WORD 'CENTRALIZING'. THE WORD CENTRAL-FIXATION MIGHT GIVE THE IMPRESSION THAT THE EYES ARE TO FIX IMMOBILE UPON A OBJECT OR POINT. THIS MUST BE AVOIDED.  FOR CLEAR SIGHT, THE EYES SHIFT, MOVE CONTINUALLY PART TO PART UPON THE OBJECT AND FROM OBJECT TO OBJECT. 'SHIFTING AND CENTRAL-FIXATION COMBINED'. THE WORD CENTRALIZING PRODUCES THE THOUGHT, FEELING OF RELAXED MOVEMENT. LIKE A BEE BUZZING AROUND THE GARDEN, MOVING FROM FLOWER TO FLOWER. A BUTTERFLY, BIRD. THE WORLD IS IN MOTION. THE EYE'S MOVEMENT MAINTAINS RELAXATION OF MIND, EYE MUSCLES, EYES AND CLEAR EYESIGHT. THE EYES HAVE MANY MOVEMENTS INCLUDING  MICROSCOPIC AND OTHER SMALL MOVEMENTS, OPTICAL DRIFT, HEALTHY HIGH FREQUENCY TREMORS; PURRING ALONG LIKE A SMOOTH RUNNING ENGINE.

IT IN MAGNIFICATION.  IT WILL PRINT CLEAR IN ANY SIZE FROM WEBSITE OR HOME COMPUTER.

 
                                                                                                                
             
PRACTICE CENTRAL FIXATION ON ANY SIZE OBJECTS; SMALL, MEDIUM, LARGE AT ANY DISTANCE; CLOSE, MIDDLE, FAR.
THE OBJECT THE EYES ARE LOOKING AT IS IN THE CENTER OF THE VISUAL FIELD AND IS SEEN CLEAREST.
THE PART OF THE OBJECT THE EYES ARE LOOKING AT IS IN THE CENTER (EXACT CENTER) OF THE VISUAL FIELD AND IS CLEAREST, CLEARER THAN OTHER PARTS THE EYES ARE NOT LOOKING DIRECTLY AT.
AVOID STARING AT A OBJECT, PART OF A OBJECT.
SHIFT FROM OBJECT TO OBJECT, PART TO PART.
SHIFTING MOVES THE CLEAR CENTER OF THE VISUAL FIELD FROM PART TO PART ON OBJECTS AND FROM OBJECT TO OBJECT THROUGHOUT THE VISUAL FIELD KEEPING THE VISION CLEAR.

Central fixation - To see one small part of a object clearest at a time in the center, clearest area of the visual field.

Shifting is combined with central fixation.

Staring, eye immobility, eyestrain, eye muscle tension and blur occur when the eyes look at one point (part) of a object for longer than a second without shifting to a new point and, when the eyes try to see all points (all parts) of a object clear at the same time without shifting from point to point, from one point to another.

The eyes must shift (move) to maintain relaxation and clear vision.

People that have unclear vision stare, squint, avoid central fixation and shifting.

The normal eye functioning with clear vision shifts to a new point every fraction of a second.

The shift may be long from one object to another object or shorter, from one part of a object to another part or the shift may be a very small, tiny shift from one tiny point to another point. Example; only 1/64 inch or less from one side of a small dot to the other side then back to the original point.

As long as the eyes move/shift, relaxation and clear vision remain.

The center, clearest area of the visual field moves with the eyes from object to object, part to part (small point to small point) on objects keeping each part of a object the eyes look at in the center of the visual field and perfectly clear.

The center of the visual field is clearest.   

The peripheral field is less clear.

See clearest with the center of the visual field.

Example; In diagrams # 1 to 5 below the circle represents the visual field.

The green dot is the center of the visual field. 

The green dot/center of the visual field is clearest.

(The exact center of the visual field is smaller than the dot and is most clear but, for this example the green dot is made larger for easy viewing).

The peripheral area of the visual field consists of all areas of the circle around, near and away from the green dot/central field.

The center of the visual field and peripheral field move with the eyes as the eyes move/shift from object to object, part to part on objects.

The head/face and body move with the eyes at the same time, in the same direction the eyes move to keeping each part of the object the eyes look at between the eyes, at eye level, in the center of the visual field.

In diagrams # 1 to # 6 the center of the visual field (green dot) moves with the eyes from object to object placing the part of the object the eyes are looking directly at in the center, clearest area of the visual field.

Move the head/face with the eyes when shifting from dot to dot.

When looking at a dot, continue to shift on the dot - shift point to point on even smaller parts of the dot for perfect central fixation and shifting.

                                                                                                                                          


                                                                                                                                            


WHEN THE EYES' 'FOVEA' (MENTAL-VISUAL ATTENTION) MOVE TO A PART OF A OBJECT; THEY CONTINUE TO MOVE 'SHIFT' UPON THAT PART. THE EYE IS ALWAYS IN MOVEMENT. THE EYE IS AT REST, RELAXED AND HEALTHY WHEN MOVING. IN REALITY THE EYE SHIFTS POINT TO POINT;  CONTINUALLY FROM ONE POINT OF FIXATION TO ANOTHER; OBJECT TO OBJECT, PART TO  PART ON A OBJECT,  SMALL PART TO SMALL PART ON A PART OF A OBJECT. SHIFTING WITH CENTRAL FIXATION COMBINED. THIS IS AN AUTOMATIC FUNCTION OCCURRING WITHOUT EFFORT, WITHOUT CONSCIOUS SUPERVISION, CONTROL. CLEAR VISION IS A AUTOMATIC SENSE; LIKE HEARING, TOUCH, TASTE, SMELL.


IT IS NORMAL TO TURN THE HEAD, FACE EYES TO THE LEFT , RIGHT... WITHOUT MOVING THE ENTIRE BODY TO GLANCE AT A OBJECT  BUT IF THE POSITION IS MAINTAINED, THE ENTIRE BODY MUST FACE THE DIRECTION THE EYES ARE FACING IN ORDER TO KEEP EYE, NECK, BODY MUSCLE RELAXATION, MOVEMENT.

AVOID INCORRECT POSTURE, INCORRECT VISION HABITS;
AVOID LOOKING TO THE LEFT, EYES DIRECTED LEFT, WITH THE HEAD/FACE, BODY FACING IN THE OPPOSITE DIRECTION TO THE RIGHT.
AVOID LOOKING TO THE RIGHT WITH THE HEAD, FACE, BODY DIRECTED TO THE LEFT.
AVOID LOOKING UP WITH THE HEAD, FACE, BODY DIRECTED DOWN.
AVOID LOOKING DOWN WITH THE HEAD, FACE, BODY DIRECTED UP.
EXAMPLE; EYES LOOKING LEFT AT A PAGE ON THE LEFT SIDE OF THE COMPUTER MONITOR WHILE THE HEAD, FACE, BODY ARE DIRECTED STRAIGHT AHEAD TO THE COMPUTER SCREEN OR TO THE LEFT OF THE SCREEN.
EXAMPLE; LOOKING UP OVER THE TOP OF EYEGLASSES WITH THE HEAD, FACE DIRECTED DOWN.
LOOKING DOWN THROUGH THE BOTTOM OF EYEGLASSES WITH THE HEAD, FACE DIRECTED UP.
BIFOCALS ALSO CAUSE THESE INCORRECT VISION HABITS.
ALL THESE INCORRECT POSTURES, VISION HABITS CAUSE EYE MUSCLE TENSION, DYSFUNCTION, EYESTRAIN, NECK, HEAD/FACE, BODY MUSCLE TENSION, IMMOBILITY, UNCLEAR VISION, ASTIGMATISM.
