  Those who blink too little and too tensely — and they comprise a majority of the sufferers from defective vision — must consciously acquire, or re-acquire, the habit of blinking often and easily. This can be done by pausing every now and then to perform a brief blinking-drill — half a dozen light, butterfly-wing blinks; then a few seconds of relaxed closure of the lids; then more blinks, and another closing. And so on for half a minute or a minute. Repeated at frequent intervals (say, every hour or so) these drills will help to build up the habit of frequent blinking during the rest of the day. A person who has become ‘blinkconscious’ will also be conscious of his own tendencies to immobilize the eyes and lids, and will be able to check the incipient stare by frequent and easy closures of the lids. Frequent blinking is especially important for those engaged in any form of difficult and detailed work, requiring close attention. When busy with such tasks, it is fatally easy to fix the eyes and lids, with resulting strain, fatigue, dryness of the cornea, inflammation and impairment of vision. Frequent and easy blinking will often bring a measure of relief that seems out of all proportion to the simplicity of the means employed.

  Besides blinking, one may, with advantage, periodically squeeze the eyes tight shut, reinforcing the action of the lids with that of the other facial muscles. This should be done on all occasions when one is tempted to rub the eyes — a barbarous and brutal method of doing with the knuckles what the beautifully adjusted eyelids can do much more safely and just as effectively. It may also be done occasionally, even when there is no itching or other discomfort in the eyes — merely to increase local circulation and stimulate the secretion of tears.

  Massage of the eyes themselves is always undesirable; but a gentle rubbing of the temples will often be found soothing and refreshing. Eye fatigue may also be relieved by rubbing and kneading the muscles of the upper part of the nape of the neck. (In certain cases of defective vision, appropriate treatment by a capable osteopath will often produce excellent results.) People who are subject to eye-strain may profitably use this rudimentary kind of massage upon themselves two or three times a day and follow it up by a period of palming.

  NORMAL AND ABNORMAL BREATHING HABITS

  As was pointed out in the first section of this book, experimental psychologists have noted a fairly regular correlation between the state of attentiveness and a modification of the normal rate and amplitude of breathing. To put it more simply, they have noticed that, when we look at something attentively, we tend either to hold our breath for many seconds at a stretch, or alternatively, if we do breathe, to breathe less deeply than at ordinary times. The reason for this is that, when we are trying to concentrate our attention, we find that the sounds and the sense of muscular movement, associated with breathing, are sources of distraction. We try to get rid of these distractions, either by breathing less deeply, or by suspending our breathing altogether during relatively prolonged periods of time.

  In their strained effort to see, people with defective vision tend to carry this normal interference with breathing to entirely abnormal extremes. Many of them, when paying close attention to something they are particularly anxious to see, behave almost as if they were diving for pearls, and remain for incredibly long periods without drawing breath. But vision depends-to a remarkable extent upon good circulation; and circulation can be described as good only when it is sufficient in quantity (which it is not when the mind is under strain and the eyes are in a condition of nervous muscular tension), and at the same time of good quality (which it certainly is not when restricted breathing has left the blood imperfectly oxygenated).

  The quantity of circulation in and around the eyes may be increased by means of relaxation, passive and dynamic. The quality can be improved by learning consciously to breathe, even while paying attention. Some of the techniques of relaxation have already been described, and I shall have occasion, later on, to mention several others. In this sub-section our concern is only with breathing.

  In correcting abnormal breathing habits, the first thing to do is to become aware that they are abnormal. Impress upon yourself the fact that, among persons with defective sight, there is a regular correlation between attentive looking and a quite unnecessary, indeed positively harmful, interference with breathing. Kept in the back of the mind, this thought will periodically pop out into consciousness; and if it does this at a time when you are paying close attention to something, the chances are that you will catch yourself behaving as though you were a pearl fisher ten fathoms under the surface of the sea. But you are not a pearl fisher, and the element in which you live is not water, but life-giving air. Therefore, fill your lungs with the stuff — not violently, as though you were doing deep-breathing exercises, but in an easy, effortless way, expiration following inspiration in a natural rhythm. Continue, while breathing in this way, to pay attention to the thing you want to see. (In later chapters of this book I shall describe the proper way of paying attention.) You will find it possible, after a little practice, to be just as concentratedly attentive when breathing normally, or even rather more deeply than at ordinary times, as it is when behaving like a pearl fisher. In a little while, you will find that breathing while paying attention has become habitual and automatic. Any improvement in the quality of circulation is reflected immediately in better vision; and when, through relaxation, quantity has also been increased, this improvement in vision will be even greater.

  In cases of failing sight, due to old age or other causes, and in certain pathological conditions of the eye, some doctors, particularly those of the Viennese school, make successful use of mechanical methods for increasing local circulation. Temporary hyperaemia of the regions round the eye is produced by dry cupping of the temples, or by the application of leeches, or sometimes by fastening round the neck a specially made elastic collar, so adjusted as to permit the blood to flow freely into the head through the arteries, while reducing the amount to return by slightly constricting the veins. None of these procedures should be tried out, except under expert medical advice; nor, indeed, is it necessary in most cases that they should be tried. Relaxation and proper breathing will bring about an equal improvement in circulation, more slowly indeed, but more safely and naturally, and by methods which are entirely under the control of the person employing them. Moreover, the resulting improvement in visual functioning and in the organic condition of the eyes will be the same, whichever means of increasing circulation are employed. The mechanical methods are no better than the self-directed, psycho-physical methods here described. Indeed, in so far as they are mechanical, they are intrinsically less satisfactory. If I mention them at all, it is merely in order to corroborate the assertion that vision and the organic health of the eyes depend upon adequate circulation.

  The extent of this dependence can be demonstrated in a very simple way. As you read, draw a deep breath and then exhale. While the air is being breathed out, you will notice that the print before your eyes becomes perceptibly clearer, blacker and more distinct. This temporary improvement of vision is due to a slight temporary hyperaemia in the head; and this, in turn, is due to the slight constriction of the veins in the neck caused by the act of expiration. More than the usual amount of blood is present in and around the eyes — with the result that the sensing-apparatus does its work more efficiently, and the mind is given better material with which to do its perceiving and seeing.

  CHAPTER VIII

  The Eye, Organ of Light

  IN INSECTS AND fishes, in birds and beasts and men, eyes have been developed with the express purpose of responding to light waves. Light is their element; and when they are deprived of light, either wholly or in part, they lose their power and even develop serious diseases, such as the nystagmus of coal miners. This does not mean, of course, that eyes must be perpetually exposed to light. Sleep is necessary to the mind that perceives, and for seven or eight hours at least out of the twenty-four, darkness is necessary to the sensing-apparatus. The eyes do their work most easily and efficie
ntly when they are allowed to alternate between good solid darkness and good bright light.

  THE CURRENT FEAR OF LIGHT

  In recent years there has grown up a most pernicious and entirely unfounded belief that light is bad for the eyes. An organ which, for some scores of millions of years, has been adapting itself very successfully to sunshine of all degrees of intensity, is now supposed to be incapable of tolerating daylight without the mitigating intervention of tinted goggles, or lamplight, except when diffused through ground glass or reflected from the ceiling. This extraordinary notion that the organ of light perception is unfitted to stand light has become popular only in the last twenty years or so. Before the war of 1914 it was, I remember, the rarest thing to see anyone wearing dark glasses. As a small boy, I would look at a be-goggled man or woman with that mixture of awed sympathy and rather macabre curiosity which children reserve for those afflicted with any kind of unusual or disfiguring physical handicap. Today, all that is changed. The wearing of black spectacles has become not merely common, but creditable.

  Just how creditable is proved by the fact that the girls in bathing suits, represented on the covers of fashion magazines in summer time, invariably wear goggles. Black glasses have ceased to be the badge of the afflicted, and are now compatible with youth, smartness and sex appeal.

  This fantastic craze for blacking out the eyes had its origin in certain medical circles, where a panic terror of the ultra-violet radiations in ordinary sunlight developed about a generation back; it has been fostered and popularized by the manufacturers and vendors of coloured glass and celluloid spectacle frames. Their propaganda has been effective. In the Western world, millions of people now wear dark glasses, not merely on the beach, or when driving their cars, but even at dusk, or in the dim-lit corridors of public buildings. Needless to say, the more they wear them, the weaker their eyes become and the greater their need for ‘protection’ from the light. One can acquire an addiction to goggles, just as one can acquire an addiction to tobacco or alcohol.

  This addiction has its origin in the fear of light — a fear which those who have it feel to be justified by the discomfort they experience when their eyes are exposed to too intense a brightness. The question arises: why this fear and this discomfort? Animals get on very happily without goggles; so do primitive men. And even in civilized societies, even in these days when the virtues of coloured glass are everywhere persuasively advertised, millions of people face the sunlight without goggles and, so far from suffering any ill effects, see all the better for it. There is every reason to suppose that, physiologically, the eyes are so constructed that they can tolerate illuminations of very high intensity. Why, then, do so many people in the contemporary world experience discomfort when exposed to light even of relatively low intensity?

  REASONS FOR THE FEAR OF LIGHT

  There seem to be two main reasons for this state of things. The first is connected with the silly craze for shutting out the light, described in an earlier paragraph. Medical alarmists and the advertisers, who exploit the opinions of these learned gentlemen for their own profit, have convinced large sections of the public that light is harmful to the eyes. This is not true; but the belief that it is true can cause a great deal of harm to those who entertain it. If faith can move mountains, it can also ruin vision — as anyone may see for himself who has watched the behaviour of light-fearing people when suddenly exposed to sunshine. They know that light is’ bad for them. Consequently, what grimaces! What frowns! What narrowings of the lids! What screwings-up of the eyes! In a word, what manifest symptoms of strain and tension! Originating in a false belief, the purely mental terror of light expresses itself physically in terms of a strained and thoroughly abnormal condition of the sensing-apparatus. Eyes in such a condition are no longer capable of reacting as they should to the external environment. Instead of accepting the sunlight easily and as a blessing, they suffer discomfort and even develop an inflammation of the tissues. Hence more pain and a heightening of fear, a confirmation of the false faith that light is harmful.

  There is also another reason for the discomfort which so many people now experience when exposed to light. They may not start with any a priori terror of light; but because their seeing organs are strained and defective, owing to habits of wrong use, their eyes and mind may be incapable of reacting normally to the external environment. Strong light is painful to the tense, strained seeing organs. Because it is painful, a fear of light develops in the mind; and this fear becomes, in its turn, a cause of further strain and discomfort.

  CASTING OUT FEAR

  The fear of light, like all other kinds of fear, can be cast out of the mind; and the physical discomfort experienced when the sensing-apparatus is exposed to light can be prevented by means of suitable techniques. When this has been done, it will no longer be necessary to black out the eyes with tinted goggles.

  Nor is this all. In the process of learning to react to light in a normal and natural way, defective seeing organs can do much to relieve the strain that impairs their visual power. Acquiring normal reactions to light is one of the essential procedures in the art of seeing. Appropriate drill in connection with sunlight will produce a valuable kind of passive relaxation; and the power so acquired of dealing easily and effortlessly with the strongest illuminations can be carried over into active life, to become an element in that dynamic relaxation of the seeing organs, without which there can never be perfect vision.

  In all cases where light causes discomfort, the first thing to do is to cultivate an attitude of confidence. We must bear steadily in mind that light is not harmful, at least in any degree of intensity we are ever likely to meet with; and that, if in fact it produces discomfort, the fault is ours for being afraid of it, or for having habitually used our eyes in the wrong way.

  PRACTICAL TECHNIQUES

  Confidence in the harmlessness of light should be translated into practice by a process of gradual habituation. If the eyes shrink from sunlight when open, start by accustoming them to sunlight when they are closed. Sitting comfortably, lean back and, ‘letting go and thinking looseness,’ close the eyes and turn them towards the sun. To avoid internal staring and the possibility of too prolonged an exposure to the light of any given portion of the retina, move the head gently but fairly rapidly from side to side. A lateral swing of a few inches will be quite sufficient, so long as it is kept up continuously.

  In some persons sunning of the eyes will produce discomfort even when the lids are closed. Where this is the case, it will be as well to start by directing the eyes at the sky, and not directly at the sun. When the light of the sky seems tolerable, one may turn for short periods to the sun. As soon as any discomfort is felt, one should turn away, palm the eyes for a little, and then start again. The closed lids may be sunned for several minutes at a stretch (with brief interruptions for palming, if the need of it is felt); and the process should be repeated several times in the course of the day.

  After a very little while most people will find that they can, without discomfort, take the sunlight upon the open eyes. The most satisfactory procedure is as follows. Cover one eye with the palm of the hand and, taking care to swing the head from side to side as before, allow the other eye to travel back and forth three or four times across the sun, blinking rapidly, lightly and easily as you do so. Then cover the eye that has been exposed to the sunlight and repeat the same process with the other eye. Alternate for a minute or so; then palm until the after-images disappear. When the eyes are uncovered, it will generally be found that vision has distinctly improved, while the organs feel relaxed and suffused with a warm sense of well-being.

  When the open eyes are sunned one at a time, in the manner described above, the light seems far less dazzling than when both are sunned simultaneously. Because the illumination seems more intense, simultaneous sunning of both eyes may result in involuntary shrinking, which is then overcome by an effort of will that results, in its turn, in a state of tension. This condition may
postpone the achievement of the complete relaxation which should normally follow the process of sunning. Nevertheless, those who wish to sun both eyes simultaneously may do so in moderation without any fear of harm. It may be noted that the process is accompanied, at first, by a copious discharge of tears and followed by after-images brighter and more lasting than those which attend the sunning of each eye separately. The tears are refreshing, and the after-images soon disappear with palming. On the whole, however, the method of sunning one eye at a time is to be preferred.

  HARMLESSNESS OF SUNNING

  The enemies of Dr. Bates’s method are fond of telling hair-raising stories about the effects of sunning the eyes. Those who do it are solemnly warned that they will go blind, either at once or (when in fact this doesn’t happen) at some future date. From personal experience, as well as from fairly extensive enquiries among people who have taught and practised the technique, I am convinced that these stories are wholly untrue. When the eyes are sunned in the manner described in the preceding paragraphs, no harmful effects ever follow. On the contrary, the organs are agreeably relaxed, circulation is speeded up, and the vision is improved. Moreover, many forms of inflammation, both of the eye and its lids, tend to clear up very rapidly when the eyes are sunned. There is nothing particularly surprising about these facts. Sunlight is a powerful germicide and, used in moderation, it acts as a valuable therapeutic agent when directed on the human body. There is no reason why it should not act upon the eyes in the same beneficial way as it acts on other external organs.
