Description: METHOD AND APPARATUS FOR STIMLULATING THE VISUAL SYSTEM BACKGROUND TO THE INVENTION A human being's visual system is comprised of a number of spacially separate regions, each of which have distinct functional roles. Generally speaking a human being's visual system comprises a sensory component, stationary or form analysis component, motion analysis component, cortex, pupil motor pathway component and psychoptical component. Information from the sensory component feeds into the stationary component and motion analysis component and finally into the cortex which functions as an end station of a human being's brain. The motion analysis component comprises a number of different cells and includes amacrine cells which respond to motion and release dopamine when stimulated by such motion. The pupil motor pathway is controlled by an autonomic component of a nervous system of a human being. The pupil motor pathway is responsible for pupillary reflexes which encompasses the following reflexes: (i) the light reflex whereby the pupil contracts if light directly enters the eye; (ii) the near reflex in which the curvature of the lens is increased such that a close object may be brought into focus; (iii) the psychosensory reflex in which the pupils dilate following sensory or psychic stimuli . The psychoptical component of the visual system is responsible for psychoptical reflexes which include fixation and fusion reflexes. There are two fusion reflexes, namely motor fusion and sensory fusion. Motor fusion enables extra ocular muscles of each eye to work together and sensory fusion enables separate images from each eye to be joined to give depth perception. It is thought that emotion and pain may influence the psychoptical component. Fixation and fusion reflexes enable the eyes to orientate themselves such that light rays from an object of interest fall on the most sensitive part of the retina, the fovea . They also allow the eyes to follow a moving object while keeping the image focused on the fovea. These reflexes are also important for binocular vision. The fixation and fusion reflexes are stimulated by object movement and/or head movement . Operation and interaction of the aforementioned components of the visual system is to date by no means thoroughly understood. It is thought by persons skilled in the relevant art that the cortex may be capable of functioning as a Fourier analyser which is capable of analysing wave motion and operating on a logarithmic as opposed to a linear scale . It is desirable to provide an apparatus and method for stimulation of the visual system of a human being which enables pupillary reflexes, fixation and fusion reflexes and stationery and motion analysis components of the visual system to be stimulated. SUMMARY OF THE INVENTION The present inventor has discovered that by applying a pattern to a surface, the pattern having regions which are located at a predetermined distance or arrangement relative to each other and which contrast visually with the surface, and moving the pattern relative to the field of vision of a person at a speed equal to or greater than a speed where the regions begin to blur, each of the aforementioned components of the visual system may be stimulated. Due to fixation and fusion reflexes a person's eyes attempt to follow the moving regions of the pattern and as such by forcing the eyes to remain focused upon a region which is not moving relative to the field of vision of the person the eyes are able to be exercised in such a way so as to correct visual abnormalities such as squint, amblyopia, errors of refraction and the inability to correctly focus. Movement of a pattern relative to the field of vision can produce a number of different results depending upon the details of the pattern and the speed of movement of the pattern relative to the field of vision. As the speed of movement of the pattern increases, the person views what appears, to the person, to be a blurred image that is typically unrecognisable; although, with certain patterns, which can usually be characterised as a wave form the pattern appears, to the person, to move relative to the field of vision at a slower speed than the speed of movement of the pattern. If the speed is then further increased, the person views, depending upon the pattern, either what appears, to the person, to be a blurred image or banding wherein one or more bands are substantially aligned with the direction of movement of the pattern relative to the field of vision. Because of the above described findings regarding the visual system's response in relation to a moving pattern the present inventor postulates that the motion analysis component and associated cortexual analysis are responsible for such findings and are therefore stimulated. It is therefore thought, by the present inventor, that the apparatus and method of the present invention may be capable of stimulating the motion analysis component and cortex of the visual system for the purpose of producing associated beneficial affects such as increasing the processing capabilities of the person whose visual system is stimulated. The present inventor also considers that such stimulation may be used to maintain cells of the brain which atrophy with age or otherwise degenerate and therefore suggests that the apparatus and method of the present invention has application in the treatment of degenerative diseases such as Parkinson's. Furthermore stimulation of the motion analysis component results in the release of dopamine and may also increase receptor uptake capacity in relation to dopamine which is important with respect to treatment of degenerative disease. The autonomic nervous system is comprised of sympathetic and parasympathetic components or pathways which are integrated in the hypothalamus . To date the autonomic nervous system has been considered to be involuntary; however, the present inventor has discovered that the autonomic nervous system can be influenced with the use of an appropriate apparatus and method of the preferred embodiment of the present invention: awareness and vegetative functions such as eye and blood pressure can be influenced. The present inventor has also found that the aforementioned use of the apparatus of the present invention results in elevated awareness while dreaming. Through use of the apparatus and method of the preferred embodiment of the present invention it has also been found that stimulation of the visual system is useful for the purpose of effecting sleep onset, in a similar fashion to 8 Hz stimulation, which is considered to effect a higher centre which is thought to be comprised of a diffuse system in the hypothalamus and frontal lobe and responsible for controlling circadian rhythms which effect dional variation in alertness. Circadian rhythms are at present not well understood; however, it is believed that the hypothalamus is associated with the release of adrenocortico trophic hormone which in turn effects the release of cortisone from the suprarenal gland and consequently effects alertness and stress levels. The present invention provides an apparatus for stimulating the visual system of a person, the apparatus comprising; a pattern having regions which contrast visually, the regions being located at a predetermined distance or arrangement relative to each other and means for moving the pattern relative to the field of vision of the person at a speed equal to or greater than a speed where the regions appear, to the person, to begin to blur.

It should be noted that the equatorial pattern of spheres 12, 28 or 32 may comprise any combination of wave forms wherein each of the wave forms may be a square wave, triangular wave, sinusoidal wave or any one of the aforementioned wave forms which is either compressed or extended in the longitudinal direction. Referring to Figures 5 and 6 poles of the spheres 12, 28 and 32 comprise white lines 36-50 and 52-66 which radiate from axial pins 14 and 16 respectively and overlay spheres 12, 28 and 32. Lines 44-50 and 60-66 are equivalent in length and shorter than lines 36-42 and 52- 58 respectively. Lines 46-50 and 62-66 bisect the angle between adjacent longer lines 38-36 and 54-52 respectively. Line 44 is removed from line 36 by an angle of 30 degrees and from line 38 by an angle of 60 degrees; whereas, line 60 is removed from line 52 by an angle of 60 degrees and line 54 by an angle of 30 degrees . Referring to Figures 7 and 8 the poles of the apparatus of Figures 1-4 comprises white spirals 68 and 70 which spiral about axial pins 14 and 16 respectively and overlie the blue surface of the spheres of the apparatus of Figures 1-4. Referring to Figure 9 the poles of the apparatus of Figures 1-4 comprise a white block pattern 72 which extends away from axial pins 14 and 16 respectively and overlays the blue surface of the spheres of the apparatus of Figures 1-4. The block pattern 72 corresponds to a zone plate wherein axial pins 14 and 16 equate to the centre of the zone plate. The distance of inner and outer edges of each block from the relevant axial pin 14 or 16 correspond to the radii of inner and outer edges of bands of a zone plate and are equal to the square root of consecutive natural numbers. Referring to Figure 10 the poles of the apparatus of Figures 1-4 comprise white lines 74-84 which overlay the blue surface of spheres of the apparatus of Figures 1-4. Line 74-82 extend from axial pins 14 and 16 respectively and line 84 connects a point part-way along line 80 with an end of line 82. Referring to Figures 11 and 12 the poles of spheres 12, 28 and 32 comprise patterns 86 and 88 which radiate from axial pins 14 and 16 respectively and overlay the surface of the spheres 12, 28 and 32 which is blue. Patterns 86 and 88 are comprised of a number of coloured concentric rings. Working from the axial pins 14 and 16 toward the outer concentric ring the rings are comprised of the following. A first concentric ring contains 8 segments 90-104 and 106-120 which radiate about axial pins 14 and 16 respectively and blocks 122-128 and 130- 136 which similarly radiate about axial pins 14 and 16 respectively. The segments 90-104 and 106-120 alternate in colour from red to green, segments 90 and 106 being green and red respectively; whereas, the bands 122-128 and 130-136 are white. The segments 90-104 and 106-120 are removed 15 degrees radially from an adjacent segment. The blocks 124-128 and 132-136 bisect the angle between adjacent segments; whereas, the blocks 122 and 130 are removed 15 degrees from an adjacent green segment and 45 degrees from an adjacent red segment. A second concentric ring of patterns 86 and 88 comprises blocks 138-168 which alternate in colour through white, red, yellow and green and 170-200 which alternate in colour through white, green, yellow and red. The third concentric ring of patterns 86 and 88 comprises alternating yellow blocks 202 and red blocks 204. The fourth concentric ring of patterns 86 and 88 is formed of yellow blocks 206 which encompass the first, second and third concentric rings of patterns 86 and 88. It should be noted that any complex number representation of a wave form or any combination of such complex number representations may be suitable for use as a polar pattern for application to one or both poles of the spheres 12, 28 or 32. In use, spheres 12, 28 and 32 are located at approximately arm's length from the eyes of the user. Spheres 12 and 32 of Figures 1, 2 and 4 are capable of producing a first treatment pattern which is useful for treatment of certain squints and is only used in relation to one eye at a time. In treating squints, it is preferred that two light sources are suitably positioned such that reflections of both the light sources are visible in the surface of the rotating sphere which is suitably reflective. Such light sources makes it easier for the user to maintain focus on a region which is stationery relative to the user by enabling the user to focus on the reflection of one of the light sources at any given moment. This enables the user to stimulate the form analysis component of the visual system and motion analysis component simultaneously. The reflections of the two light sources also enable the user to exercise their eye by shifting the focal point of their eye periodically from one of the reflections to the other of the reflections. It is important to ensure the eye is exercised while following the below prescribed method of treatment for squints as such exercise increases eye movement and subsequently avoids elevation of intraocular pressure. It must also be kept in mind that blood pressure may be elevated with use of the below prescribed method of treatment for squints regarding patterns 22 and 24 and as such general exercise and weight maintenance is required to control blood pressure. Furthermore, double vision may ensue from use of the first treatment pattern and because a fifth treatment pattern which is discussed below is useful for correcting double vision, the first treatment pattern should be used in conjunction with the fifth treatment pattern. The sphere 12 or 32 is orientated such that the user can view a pattern which extends about the equator of the sphere 12 or 32. Any one of patterns 22, 24, 30 or 34, or any combination of such patterns may be applied to spheres 12 or 32. The user is to view the sphere without eye glasses for a period of time ranging from 2-5 minutes while the sphere 12 or 32 is rotated manually at a speed equal to or greater than a speed where the pattern upon the surface of the sphere 12 or 32 begins to blur. While viewing the pattern the user must periodically shift the point of focus of their eyes from one of the reflections to the other of the reflections which reflect from the equatorial pattern. By rotating the pattern of Figures 1 and 3 at a speed of 2-10 revolutions per second the user views what appears, to the user, to be seven bands which are aligned with the direction of movement of the pattern. Two outermost bands are white while two inner bands which are adjacent to a central band are yellow. The white bands coincide with outer portions of the white square waves while the yellow bands correspond with outer portions of the yellow compressed triangular waves. Bands between the white and yellow bands can be considered to be blurred and grey while the central band is blurred and creamy yellow. For treatment of a left eye the sphere is rotated such that the pattern moves in a direction from left to right, relative to the user, for a period of time of 2-5 minutes . For treatment of a right eye a procedure the reverse of that described above in relation to the left eye is followed. The patterns 24 and/or 26 or 30 of Figures 1, 2 and 3 are capable of producing a second treatment pattern which can be used for eye exercises and relaxation, tear film maintenance, vision improvement or focal point adjustment, inducement of sleep onset, inducement of lucid dreaming and dream recall, brain cell stimulation for the purpose of brain cell maintenance, and treatment of degenerative diseases and/or processes such as Parkinson's Disease. In order to produce the second treatment pattern the applied patterns 24 and/or 26 or 30 must move in a downward direction relative to the field of vision of the user. Such downward movement of the applied patterns can be provided with use of the apparatus of Figures 3. Sphere 28 is illuminated with two overhead light sources in a similar fashion to that explained above in relation to sphere 12 or 32 and the sphere 28 is similarly located relative to the user such that the user can view the equatorially applied patterns which extend about the equator of sphere 28. The sphere 28 is rotated manually in a downward direction, relative to the field of vision of the user, at a speed equal to or greater than a speed where the applied pattern begins to blur; the moving pattern is typically viewed with both eyes for a period of time ranging from 2-5 minutes. While viewing the applied pattern the user periodically shifts the point of focus of their eyes from one of the reflections to the other of the reflections in a similar fashion to that described above in relation to the first treatment pattern such that the eyes of the user are exercised while viewing the rotating pattern. The pattern may be viewed with only one eye. It is preferred that if the pattern is viewed with one eye that the user, if possible, alternates viewing between each eye of the user. The sphere 28 is ideally rotated at a speed ranging from 2-10 revolutions per second wherein the pattern 24 and 22, when applied to the sphere 28 are such that twenty wave lengths of the patterns 24 and 22 fit within the equatorial circumference. As such, patterns 24 and 26 move with respect to the field of vision of the user at a frequency ranging from 40-200 Hz. The pattern 30 as applied to sphere 28 is such that thirteen wavelengths of the pattern 30 fit within the equatorial circumference. As such, when the sphere 28, with its surface displaying the pattern 30 is rotated at a speed ranging from 2-10 revolutions per second, the pattern 30 moves with respect to the field of vision of the user with a frequency ranging from 26-130 Hz. Use of the second treatment pattern results in the user viewing what appears, to the user, to be seven bands, as explained above in relation to the first treatment pattern with respect to similar patterns, with the exception of the red circles 26 of Figure 2 which, depending on the speed of rotation of the sphere 12 result in another source of stimulation being overlayed over the top of the aforementioned banding. As explained the path in relation to the first treatment pattern the blood pressure may be elevated with use of patterns 24 and 22 as applied to the apparatus of Figure 3 and as such, general exercise and weight maintenance is required to control blood pressure. Pattern 34, when applied to sphere 28 and used in a manner as described in relation to the second treatment pattern is capable of producing a third treatment pattern which is useful for vision improvement, eye exercise and relaxation, brain cell stimulation for the purpose of brain cell maintenance and treatment of degenerative diseases and/or processes such as Parkinson's Disease. Sixteen wavelengths of the pattern 34 fit within the equatorial circumference of the sphere 28 or 32 such that when the sphere 28 is rotated at a speed ranging from 2- 10 revolutions per second, the sine wave of the pattern 34 moves relative to the field of vision of the user at a frequency ranging from 32-160 Hz. Patterns of Figures 5-8 and 10, when applied to poles of any one of spheres 12, 28 or 32 is capable of producing a fourth treatment pattern which is useful for the purpose of vision improvement, eye exercise and relaxation, brain cell stimulation for the purpose of brain cell maintenance and treatment of degenerative diseases and/or processes such as Parkinson's Disease. Spheres 12, 28 or 32 are positioned relative to the user such that the user is able to view one of the poles of such spheres. By accordingly positioning such spheres and rotating them at a speed ranging from 2-10 revolutions per second the user views two substantially concentric bands . In using the fourth treatment pattern, the user should follow the following program wherein, for the purpose of explanation, the patterns of Figures 5-8 and 10 are divided into four quadrants, as viewed from the position of the user viewing the fourth treatment patterns, the first quadrant being the upper right hand quadrant, the second quadrant being the upper left hand quadrant, the third quadrant being the lower left hand quadrant and the fourth quadrant being the lower right hand quadrant : (1) The pattern is rotated relative to the user in either direction while the user, viewing any one of the patterns according to Figures 5-8 or 10 focuses, with both eyes, on an outer band of the fourth treatment pattern in a position substantially between the first and fourth quadrant and then proceeds to sequentially focus on inner bands in positions which lie substantially in a line between the point of focus on the outer band and the concentric centre of such bands; (2) The procedure of (1) is repeated starting at an outer band at a position substantially between the first and second quadrant and moving toward the concentric centre of the bands; (3) The procedure of (1) is repeated starting at an outer band at a position substantially between the second and third quadrants and moving toward the concentric centre of the bands; (4) The procedure of (1) is repeated starting at the outer band at a position substantially between the third and fourth quadrant and moving in a direction toward the concentric centre of the bands; (5) The procedure of (l)-(4) is repeated in a reverse direction starting at the outer band at a position between the second and third quadrants and moving about the fourth treatment: pattern in a clockwise direction, as opposed to anti-clockwise direction. The above program may be used in relation to just one eye wherein use in relation to the right eye requires (l)-(4) to be repeated with the pattern rotating in an anti-clockwise direction relative to the user and use in relation to the left eye requires (5) to be repeated with the pattern rotating in a clockwise direction relative to the user. The patterns of Figures 6 and 8 should be used in relation to (l)-(4) above while patterns of Figures 5 and 7 should be used in relation to (5) above. The patterns of Figure 10 can be used in relation to both (l)-(4) and (5) above. The pattern of Figure 10 can be rotated in either direction when being viewed with either the left or right eye . The pattern of Figure 9 when applied to any one of spheres 12, 28 or 32 is capable of producing the fifth treatment pattern which may be used for eye exercise and relaxation, tear film maintenance and is particularly useful for reducing intraocular pressure. The fifth treatment pattern is to be used in accordance with the method described above in relation to the fourth treatment pattern. The pattern of Figure 9 is positioned relative to the user such that, when the sphere 12, 28 or 32, the poles of which contain the pattern of Figure 9, is manually rotated the user views, what to the user appears to be, seven substantially concentric bands. The pattern of Figure 9 can be used in relation to both (l)-(4) and (5) of the procedure described above in relation to the fourth treatment pattern. The pattern of Figure 9 can be rotated in either direction when viewing with either the left or right eye. It is preferred that the pattern of Figure 9, as applied to any one of spheres 12, 28 or 32 is rotated at a speed ranging from 2-10 revolutions per second. Patterns of Figures 11 and 12 may be applied to any one of spheres 12, 28 or 32 for the purpose of producing a sixth treatment pattern which is useful for eye exercise and relaxation, tear film maintenance, vision improvement, inducement of lucid dreaming and dream recall, brain cell stimulation for the purpose of brain cell maintenance and treatment of degenerative diseases and/or processes such as Parkinson's Disease wherein the pattern which the user is viewing should be appropriately positioned relative to the user and rotated at a speed ranging from 2-10 revolutions per second such that the viewer views what appears, to the user, to be four substantially concentric bands. The user should follow the program outlined above in relation to the fourth treatment pattern wherein the pattern of Figure 12 should be used in accordance with (l)-(4) and the pattern of Figure 11 should be used in accordance with (5) . It should be noted that the methods described above in relation to treatment patterns 1-6 should be carried out on a daily basis wherein the particular details of the prescribed program or procedure may be modified according to the requirements of the user.
