Abstract
There is a need to provide devices and methods which can be used for determining whether or not a subject (and especially a child) under treatment is actually wearing their spectacles. Determining the level of a subjects compliance to wearing their spectacles over a period of time would assist in the treatment of a wide range of ocular diseases and visual defects, such as amblyopia, myopia and hyperopia. Spectacles 4 have a sensor or monitor 10 such as temperature sensing means or contact sensing means, e.g. a switch which is arranged, in use, to detect when the spectacles are being worn by a subject such as a child 2. The sensor may have processing means arranged to receive first and/or second signal respectively indicating âwearingâ ânot wearingâ, and thereby determine when the spectacles are being worn.
Description
SPECTACLES
The present invention relates to spectacles, and to uses thereof for treating a wide range of eye and visual disorders, such as myopia, hyperopia, astigmatism or amblyopia etc. Myopia or "shortsightedness" is a condition of the eye where the light that conies in does not directly focus on the retina, which is in the hack of the eye. Because of this, the image that one sees is out of focus when looking at a distant object but comes into focus when looking at a close object. Hyperopia or "longsightedness", on the other hand, is a defect of vision caused byan imperfection in the eye (often when the eyeball to is too short or the lens cannot become round enough), causing difficulty when focusing on near objects, and in extreme cases causing a sufferer to be unable to focus on objects at any distance. Astigmatism is an optical defect in which vision is blulTed due to the inability of the optics of the eye to focus a point object into a sharp focused image on the retina, which may be because of an irregular or toric curvature of the cornea or lens.
Amblyopia, otherwise known as lazy eye, is a disorder of the visual system that is characterized by poor vision or lack of vision in an eye that is othenvise physically normal. The problematic eye is typically healthy but, due to development issues, the visual information received at the hack of the eye and the neural information interpreted by the brain is not well transmitted or recognized. Amblyopia affects approximately 29/o to 5% of children. Amblyopia can he treated using an occlusive eye patch in a technique known as "patching", which accounts for approximately 90% of work in childrens' eye clinics. Results have also shown that the duration of treatment of amblyopia is long, expensive, with poor outcomes, and may not reach the accepted level of vision at discharge. Hence, the resultant outcome of ineffective treatment is residually amblyopic children who remain residual amblvopic adults with a reduced quality of life.
Myopia, hyperopia, astigmatism and amhlyopia, as well as many other visual disorders, can be treated by the use of spectacles or "glasses", which can be worn by both adults and children. However, the problem with spectacles is that although it is assumed that the subject is wearing them, in reality, some subjects, especially children, do not wear the spectacles at all, while others wear them, but possibly only for short periods during the day and/or at the wrong times. Therefore, the use of spectacles for treating visual defects in children in particular fails in many cases mainly due to the lack of co-operanon from the child to undertake the continual treatment that is needed. Other problems associated with wearing spectacles include victimisadon, poor cosmetic appearance of the spectacles, discomfort during treatment and a lack of confidence caused through treatment.
to There is therefore a need to provide devices and methods which can he used for determining whether or not a subject (and especialiy a child) is actually wearing their spectacles. Determining the level of a subject's compliance to wearing their spectacles over a period of time would assist in the treatment of a wide range of ocular diseases and visual defects, such as amblyopia, myopia and hyperopia.
Thus, according to a first aspect of the invention, there are provided spectacles comprising a sensor, which is arranged, in use, to detect when the spectacles are being Referring to Figure 4, there is shown the data generated front the inventors' own pilot study in which they demonstrated, for the first time ever in children with amblyopia, that there is a proportional relationship between the length of time that a subject wears their spectacles and the percentage improvement in their vision. Indeed, wearing spectacles for approximately 12 hours a day resulted in a 60% improvement in vision compared to subjects who did not wear glasses, and the direct linearity of the response shown, in Figure 4, was unexpected. . The inventors were very surprised to observe such a strong correlation between the improvement in vision and the amount of spectacles wearing. The data demonstrates that wearing spectacles is a significant part of treatment of visual defects (for example amblyopia in addition towearing an occlusive eye patch, and signifies a clear change in therapies that should be used in future Advantageously, since compliance to wea ng spectacles is one of the main hindrances to successful fleatment of many visual or ocular defects, such as amblyopia, the spectacles of the first aspect will have significant applications in a clinical setting by informing clinicians about the compliance of their patients.
The sensor may he integrated inside the frame of the spectacles. Alternatively, the sensor may he attached to the frame of the spectacles, and preferably an arm of the frame of the spectacles. The sensor may be located (either in or on the frame) at a position which, when worn by the subject, corresponds to the bridge of the subject's to nose. Preferably, however, the sensor may be located at a position which, when worn by the subject, corresponds to a side of the subject's head, and preferahiy at least adjacent the subject's temple. The inventors have found that placing the sensor on the side of the spectacles improves wearability, and decreases the chance that the subject may he enibarrassed to wear them. It is makes the spectacles more comfortable to wear and does not restrict vision. Furthermore, by placing the sensor at least adjacent the subject's temple improves the sensitivity of detection of when the spectacles are being The sensor maybe capab'e ofgeneratinga first signal when the spectacles are being worn. The sensor may be capable of generating a second signal when the spectacles are not being worn. The sensor may comprise processing means arranged to receive the first and/mr second signal, and thereby determine when the spectacles are being worn.

Following the period during whch wearing the spectacles has been monitored, the method may comprise downloading the data stored in the memory which corresponds to the first and/or second signal. The clinician may then assess when, and for how long, the subject has been weanng the spectacles. Thus, die methods determine patient compliance in wearing the spectacles.
All of the features described herein (including any accompanying claims, abstract and drawings), and/or all of the steps of any method or process so disclosed, may be to combined with any of the above aspects in any combination, except combinations where at least some of such features and/or steps are mutually exclusive.
Embodiments of the invention \vffl now be further described, by way of example only, with reference to the following Examples, and to the accompanying diagrammatic drawings, in which:-Figure 1 shows a child wearing one embodiment of a pair of spectacles fitted with a dose monitor according to the invention; Figure 2 shows an enlarged view of various components of the dose monitor shown in Figure 1; Figure 3 is a graph illustrating an example of data recorded by the dose monitor. The axis represents time (days) and the y-axis represents temperature difference (°C); and Figure 4 is a graph showing the improvement in vision during an 18 week pilot study in which a subject wore spectacles in relation to dose.
Example
Referring to Figure 1, there is shown a subject 2 (e.g. a child) wearing a pail-of glasses (also known as spectacles) 4 having two lenses 6 and arms 8. Glasses or spectacles wearing is usually prescribed to treat children suffering from various eye and visual disorders, such as short-sightedness, long-sightedness or amblyopia. A first embodiment of a dose monitor 10 is attached to one of the arms 8 of the spectacles 4, by which it is possible to monitor when, and to what extent the subject 2 wears the spectacles 4. For example, the subject 2 can he monitored over a set period of time, for example at least a week. The dose monitor 10 monitors compliance of the subject 2 to wearing the spectacles 4 by detecting and recording the temperature difference between two surfaces.
Referring to Figure 2, there are shown the major components of the dose monitor 10.
The monitor 10 essentially consists ot first and second printed circuit boards (PCB) 12, 14, which are powered by a coin cell battery 20 of voltage 3V. The PCBs 12, 14 are attached together by mutually engaging attachment means 16,18 such that they sandwich one arm 8 of the pair of spectacles 4, with the first PCI-3 12 being disposed on to one side of the arm 8 contacting the skin near the subject's temple, and the second PCB 14 being disposed on the opposite side of the arm 8, and not in contact with the subject's temple. The mutual positioning of the PCBs 12, 14 is such that a temperature differential is created between the two surfaces, with the PCI3 12 contacting the subject's temple being at a higher temperature than the other PCB 14.
The dose monitor 10 detects the temperature difference between the ttvo fiat surfaces of the PCBs 12,14 by means of two digital temperature sensors 22, 24, one being provided in each PCB 12,14. These sensors can allow wireless monitoi-ing of temperature @.e.
without batteries), for example the TSR ASIO wireless SAW temperature sensor (Senseor, France. Temperature measurements are made at five minute intervals for a minimum period of 21 days, and the data is stored on an Electronically Erasable Programmable Read-Only Memon-EEPROM) chip 26, which connected to one of the PCBs 12,14. Tn order to initiate the dose monitor 10, before a subject 2 is tested, it is first connected to a computer (not shown). The subject 2 then wears the spectacles 4 for the 21 day period during which temperature measurements are taken. After the measurements have been taken, the monitor 10 is again connected to the computer in order to download the data from die memory chip 26.
Referring to Figure 3 there is shown an example of a partial data recording derived from the spectacles monitor 10 as a time trace, with time on the x-axis (in days) and difference in temperature (in °C) on the y-axis. The recording shows data over a 21 day period.
Spectacles 4 wearing is determined as a deviation from the baseline 28 (i.e. near 0° on the v-axis). \Vhen the spectacles 4 are being worn, there is a greater temperature difference between the two surfaces of the monitor 10, which appear on the trace as a deflection or peak 30 away from 2ero (approximately 1 degree difference). The temperature difference between the two surfaces also fluctuates, leading to a spiky appearance of the trace during glasses 4 wearing.
Referring to Figure 4, there is shown data generated from the inventors' own pilot study in which they demonstrated, for the first lime, that improvement in vision in a subject 2 is strongly correlated to the amount of the spectacles 4 w'earing. Tndeed, the graph shows to that there is a proportional relationship between the length of lime that a subject 2 wears their spectacles and the percentage improvement in their vision.
In a second embodiment, the dose monitor 10 includes a contact sensor (not shown) or proximity sensor (not shown) instead of temperature sensors 22, 24. The contact sensor is includes a contact-sensitive switch that is in a closed configuration when placed in contact with the subject 2, and in an open configuration when not in contact with the subject 2. When the spectacles 4 are worn by the subject 2, the switch is urged to contact the subject's 2 temple, and closes such that a first signal is generated. however, when the spectacles 4 al-c taken off, the switch is open, thereby generating a second signal. The proximity sensor is capable of detecting where the spectacles 4 are close to the subject 2, hut without the need for any physical contact.
In a third embodiment (not shown), the dose monitor 10 is incorporated inside the arm 8 of the spectacles 4 rather than being attached to the outside of the arm 8. It is envisaged that the spectacles 4 having the dose monitor 10 can be used in combination with other methods, which monitor the amount of patching of the eye by a subject 2, since patching is often used in combination with spectacles wearing to treat amblyopia.
Advantages of the spectacles 4 and dose monitor 10 of the invention reside in the efficient manner by which it can lie used to monitor the frequency and duration that a subject 2 wears their spectacles 4. The monitor lOis, in effect, a way of policing whether or not a subject 2 wears their spectacles 4.
