Abstract

An optical system, for treating dyslexia, comprises a pair of lenses, one 12 of which is clear to be used in association with one eye of a patient, and the other 11, 15 of which has a coloured portion and which is to be used in association with the other eye of the patient. When the patient views a target surface, usually white, through the lens system the image interpreted by the patient's brain changes from an initial colour corresponding with the colour of the coloured lens to the colour of the target surface, and following this treatment the patient is then able to read without the visual disturbance associated with dyslexia. The lens pair may be for spectacles or contact lenses, or a supplementary attachment for spectacles. <IMAGE>

Description

OPTICAL SYSTEM FOR TREATING DYSLEXIA This invention relates to an optical system for treating dyslexia, and particularly to minimise the effects of visual disturbance in reading caused by dyslexia.
The visual defect of dyslexia is well known, and need not be discussed in detail, but is a long standing problem for which at present there are no easily arrived at cures. This is a problem for which an easily carried out treatment would be particularly advantageous for children, who will otherwise suffer in their development by not being able to keep up with other children in the class not having this defect.
The invention is based on the surprising discovery that use of a novel form of lens system can result in a remarkable and unexpected cure of the effects of dyslexia, at least on a temporary basis.
The invention therefore provides, in one aspect, a novel lens system for use in the treatment of dyslexia, and which comprises a pair of lenses, one of which is clear to be used in association with one eye of a patient, and the other of which has a coloured portion and which is to be used in association with the other eye of the patient.
The coloured portion may comprise a filter which is positioned in a central region of the lens, and preferred colour filters are blue, red or green.
The pair of lenses may comprise "contact lenses", but preferably they are incorporated in a pair of spectacles.
Alternatively, the pair of lenses may comprise an attachment which can be connected to a set of spectacles and flipped up when not in use, or flipped down to a position in which each lens overlies a respective one of the existing lenses of the spectacles in the manner of a set of tinted sunglasses which can be flipped up or down as required.
The invention further provides a method of treatment of dyslexia and other optical disorders using a novel lens system according to the invention.
In carrying out a method of treatment according to the invention, it is preferred to first test the patient to find out which eye is the "leading eye". Once this has been determined, a coloured lens is positioned in front of the leading eye, and a clear lens in front of the other eye. The patient is then required to view a target surface which is preferably white, and the surprising result is obtained that, in a fairly short period of time, say up to 30 seconds, the image which the patient's brain interprets is found to change from an initial colour which corresponds with the colour of the coloured lens to the colour (white) of the target surface.
Following this treatment, the patient is then able to read without the visual disturbance associated with dyslexia.
The treatment may be helped by a temporary occlusion of the eye.
The treatment imposes an alteration, at least temporary, in the way in which the patient will be able thereafter to view objects, and the dyslexic effect is overcome and the patient is able to see normally, or certainly in an improved manner.
The coloured lens may be made quite simply by providing a small circular coloured portion which can be located e.g. by simple adhesion to a central region of an otherwise clear lens. The size of the coloured portion should be sufficient to cover the pupil of the leading eye of the patient.
In addition, it may be advantageous for the specialist treating the patient to use different density of colour/tint and/or colour for each eye to suit patient requirements.
Examples of the invention will now be described in detail with reference to the accompanying drawing, in which Figure 1 is a perspective illustration of a set of spectacles provided with a novel lens system according to the invention for use in the treatment of dyslexia or other visual disturbance; and Figure 2 is a diagrammatic illustration of application of the invention to a contact lens for use in the treatment of dyslexia.
Referring now to the drawings, there will be described embodiments of novel lens systems according to the invention for use in the treatment of dyslexia or other visual disorders, and in which each system comprises a pair of lenses, one of which is clear to be used in association with one eye of a patient, and the other of which has a coloured portion which is to be used in association with the other eye of the patient.
The coloured portion comprises a filter which is positioned in a central region of the lens, and preferred colour filters are blue, red or green.
Figure 1 shows an embodiment in which the lens system is applied to a pair of spectacles 10, in which the left hand lens 11 is a tinted lens, and the right hand lens 12 is a clear lens.
Alternatively, the pair of lenses of the lens system may comprise "contact lenses", one of which is shown by reference 13 in Figure 2, which comprises a clear annular periphery 14 and a circular central coloured portion 15 which will be made also to allow colour change to occur, as will be described below.
As an alternative to the incorporation of the lens system in a pair of spectacles 10 as shown in Figure 1, the pair of lenses may comprise an attachment, somewhat similar to a tinted sunglass attachment, which can be connected to a set of spectacles and flipped up when not in use, or flipped down to a position in which each lens overlies a respective one of the existing lenses of the spectacles.
The method of treatment of dyslexia and other optical disorders using the novel lens system according to the invention will now be described.
In carrying out the method of treatment of a patient found to have dyslexia, or similar visual disorder, tests are first carried out on the patient to find out which eye is the "leading eye". Once this has been determined, a coloured lens is positioned in front of the leading eye, and a clear lens in front of the other eye.
The patient is then required to view a target surface e.g. a white painted wall or other white background, and the surprising result is obtained that, in a fairly short period of time the image which the patient's brain interprets is found to change from an initial coloured view which corresponds with the colour of the coloured lens e.g. blue, to the actual white colour of the target surface. This may be helped by a temporary occlusion of the eye.
Following this modification of the behaviour of the patient's eyes, improved reading by the patient can then be carried out.
Usually, the leading eye of most patients is the left eye, which is why Figure 1 shows lens 11 located to cover the left eye of a patient, but evidently in cases in which the patient has a right leading eye, an alternative set of spectacles or lenses will be provided, so that a central coloured portion can cover the pupil of the right eye.
In addition, it may be advantageous for the specialist treating the patient to use different density of colour/tint and/or colour for each eye to suit patient requirements.
