More Imagination Insights
However, we don’t really see any "pixels" or any undigested lights and shadows. In fact, we are unable to see anything at all until our mind recognizes or makes the best guess about what we are actually looking at, basing on what the mind has learned through its entire lifetime. If it’s an unfamiliar object, the mind will analyze the smaller parts of it to see if they are familiar. In this way the mind will learn the new object and recognize it in the future.
In other words, to see means to perceive interpreted, already meaningful information about real objects based on your mind’s past experience. We see a tree with leaves and apples, but not a colorful patchwork of lights and shadows. We know what an apple tree is.
We see an object with the visual center of our mind and by imagining the object. Imagination, that is, building images from the raw data, be it eyes or memory, is a wonderfully accurate word for the process.
Imagination as a mental activity is the driving force of the visual system, not another way around. Without imagination you’d be totally blind even if the eyes still provided raw electric signals – they just wouldn’t be used by the mind. When imagination is at work, it also directs mind's attention to interesting details and drives the muscles of the eyes to shift and focus them accordingly, all happening automatically and unconsciously.
It’s clear now that lowered eyesight occurs when you underuse or suppress imagination, usually by replacing it with an abusive fixation of attention on the eyes as physical organs, in vain attempts to command them "to see better". You can feel it as strain and it causes all sorts of trouble. The attention is no longer properly directed by the imagination process, and tends to see all (and nothing) at once. The eyes become misfocused and their shifting stops because the eye muscles no longer receive meaningful commands.
It’s hard to tell what is the cause and effect of this condition, we have a bit of "chicken and egg" problem here. Perhaps somewhere on the edge, where imagination fails due to actual lack of information, like too far or too dim, the mind may happen to insist on seeing the impossible and instead of imagining finer detail, somehow turns its attention to the eyes. The vision lowers, so the imagination works further worse, and thus the vicious cycle is born, which becomes permanent if the abuse is practiced long enough.
Fortunately, it’s not likely that the visual mind completely stops imagining. We are still able to recognize most objects, even though the image is blurry. The blur is in fact only a failure to imagine finer details and textures of objects. The mind imagines objects in large strokes, ignoring details and thereby not producing the finer attention and shifting and focusing commands to the muscles of the eyes.
Therefore, to cure imperfect sight, you should use all means to divert attention from the eyes and wholeheartedly relinquish the control to imagination. It is important to realize that vision is an involuntary process happening in the mind, not in the eyes. The eyes should be ruthlessly left alone, and then imagination of finer details instantly becomes possible again.
One technique that recently helps me leave my eyes alone is to imagine that the image I see doesn't come through the eyes but is already in my mind. Like if there was no bone dome over the brain an the image projected directly on the visual mind. It takes me several seconds to believe, and when I get it, it's usually an instant relief. Also, that funny calm feeling that the image is "already there" and should not be made out, is exactly the one that previously accompanied all my clear flashes.

Why Imagination Works
I agree that imagination is perhaps the most important technique. Or it's memory. (I can't really tell the difference between memory and imagination. You can't imagine anything you never saw, so even though formally imagination is defined as visualizing things that you didn't see, it is still composed of things that you did see. At least, imagination and memory feel the same to me, so far. But Dr. Bates did discriminate imagination and memory.)
It turns out the imagination is as essential as vision itself. People with normal sight continuously imagine what they're looking at, and in this way they see it. The normal mind is focused on imagining the regarded object, and vision just follows it, filling the imagined detail with real data. The strained mind is focused on the vision — blurry vision, and imagination is suppressed. David is right in saying that imperfect sight is a disorder of attention. Imagination drives attention and shifting from one detail to another. Without concurrent imagining the object you're looking at, you cannot shift and therefore cannot see.
I have been ignoring imagination techniques for a long time. I found it kind of boring and childish. There seemed nothing interesting to remember or imagine. Besides, when I tried to imagine anything I began to conjure up words. Pictures didn't really come to my mind, and I was wondering if I understood imagination the right way at all. I couldn't understand how much really vivid and visual the pictures should be.
It turns out that the imagined pictures should be just as vivid as vision, and getting them is easy. You should just want to imagine something, let it come to you and stop preventing it.
I recently watched an old series "My name is Earl", where Earl tried to compose an essay, but couldn't imagine anything. His imagination was screened as a plain white space with no objects around, except Earl himself, and a black-eyed gymnast, a haunting image from another guy's essay, about whom Earl didn't want to write. The gymnast kept popping up driving Earl crazy and then he (the gymnast) said "I won't go away until you stop thinking about me!" Then Earl somehow managed to let go of the fixed idea and his imagination immediately fountained.
After a good laugh I thought that the gymnast is exactly what happens to me when I try to imagine anything, where by gymnast this time I mean the focus on vision. My mind cannot imagine anything until it's locked on seeing, even with my eyes closed. When I somehow manage to stop worrying about seeing just for a second, I am immediately flooded with a bunch of shockingly vivid images and memories. So far it doesn't last longer than a second, because it's just overwhelming, and my scared mind jumps off to habitual "seeing" again. But I am sure that with practice, it's possible to persuade the mind that it's okay to keep imagining.
Even glimpses of imagination do wonders to vision. All tension and pulling sensations around eyes disappear, redness of sclera clears up in few minutes, and clear flashes begin immediately. And what's great about imagination-induced clear flashes, is that it feels different, like if you already have the detail, you're no longer making it out.
So I'm now a big fan of imagination techniques. It is important to find inspiring images to imagine. Personally I find it good to imagine well-lit objects like rocks, trees, sea shore on bright sunny days, surrounded with bright blue sky.
One other technique I currently use is to keep telling myself to not try to see under any circumstances, even when I "need" to see. Trying to see always fails and is therefore useless, but the habit is deeply ingrained, an it increases the strain to the degree when you can no longer imagine anything. So take a couple relaxed breaths, stop trying to see and then imagine. Swinging the head slightly, noticing the movement relative to stationary shoulder or feet is another good way to stop trying to see. Keep repeating like that all the time. We need to persuade our minds that not trying to see is okay, and go for imagination. Gradually.

Figure out what you're doing to make it not work
I like the idea of observing myself carefully and figuring out what exactly I'm doing to sabotage my vision. I guess it's the habit of resisting the strain, which makes the things worse. When strain occurs, I unconsciously perform some counter-work to compensate the disagreeable state. I think this counter-work establishes the balance of forces that makes eye disorders so unbelievably persistent.
My mind constantly fools me by trying to hide the strain and the counter-work I'm doing, letting it slip habitually into the subconscious area. It takes some attention and patience to not let it happen, and keep it within conscious field. Interesting...

Practice with Sunlight: Mistakes and Lessons
All newbies seem to make the same mistake. They think the sun has some magic power to cure their eyesight and all they have to do is to let as much light as possible in their eyes for as long as they can. With neophyte's ardor they look directly at the sun only to produce lasting scotomas and other disagreeable symptoms, to no benefit whatsoever. My own scotoma (the worst part of it) lasted for several weeks, and its remnants continued for months, after looking just once at a winter sun for 40 mins. After that I elaborated some safety rules that allowed me to look at the sun without unpleasant consequences, but still I didn't have any real benefit from sun gazing.
The truth is that all "magic" happens inside your mind, and not through any external object or influence, be it sunlight or whatever. When you know mental relaxation, you can use bright light as an aid to that magic, to let it come easier and seep deeper. But there's absolutely no recommendation to sungaze otherwise. You will do it wrong and only make your strain worse.
As you know, I have recently become an advocate of deep body relaxation as the first step in the Bates practice. It really gave me some knowledge of how my mind actually works and what is mental relaxation at all, how it feels. Now I am applying that experience to relearn all Bates practices, including sun treatment. Here is how I do it now.
First, I look at the sun with my eyes closed and imagine/remember a "rest point" in some part of my body, e.g. in my foot, or in a shoulder. Then I carefully open my eyes and look at the sky, still keeping my attention on the rest point. When I do it wrong and lose the memory of the rest point, the sky appears intolerably bright, not to mention the sun; I begin to squint, frown and blink nervously. In this case I close the eyes and remember the rest point again. When I do it right, the sky and the sun do not seem too bright at all; the eyes open wide all by themselves, and blink easily and comfortably. So far I've been able to stay in this state for few seconds. To make it longer, I swing my head and eyes slightly from side to side and notice the opposite movement relative to the rest point.
The point of this practice is to learn to stay comfortable with eyes opened in bright light, but not to just let as much light as possible into the eyes. It's not even necessary to look directly in the sun. In fact, I avoid looking directly at the sun for longer than a fraction of second, as I swing my head and eyes from side to side, because when I look longer, I can feel and identify that I'm immediately beginning to stare.
After such practice vision is improved and no disagreeble symptoms appear.
P.S. If you have white skin, it can age quickly when exposed to much sun. Consider wearing some protecting mask on your face.

My Recent Progress & Body Relaxation Technique
I think we should never give up our Bates practice, but I also think we should be smart, and move on to try different ways until we find what works best for us. In my case, the thing I've been looking for was effortlessness of the mind. I could never discern this feeling, as it was almost otherworldly to my mind, habitually strained and always whirling with thoughts. So whatever I practiced, it was still with effort, and I couldn't even tell.
Then I remembered what Dr. Bates wrote that when the mind is perfectly relaxed, the entire body and all nerves are relaxed too. So I looked around and found a technique for deep body relaxation. This technique was recommended to me by one Bates teacher, but it's also well known in yoga and other practices. It's very simple. I lie down on my back, close my eyes, and scan my body, shifting my attention from one part of the body to another, relaxing each muscle and imagining that part heavy and warm. I spend one breath on each part. I breathe with my belly and notice that the peak of relaxation in each part is reached in the pause after breathing out. The point of this exercise is to divert the mind from thoughts and follow your shifting inside the body. Even a few minutes spent inside the body has a miraculous effect on the mind. The whirl of thoughts dismisses and the effortlessness and calmness come out. Complete silence and relaxation comes to all parts of the body. When you stand up, you find all symptoms of strain quickly and efficiently relieved.
I practiced this exercise three times a day for a few months, and I really liked it, because it's always a rest. Quite soon I began noticing that I can consciously remember that indescribable feeling of effortlessness, comfort and calmness of the mind at any time of the day, and when I do, my vision instantly improves. Any Bates technique works like a charm in such moments. And in reverse, in the days when I can't remember this state, all methods fail. I've practiced this long enough to become convinced that this has the decisive influence on all my Bates practice.
The funniest thing is that when I think about it, I see that my discovery is nothing else but what Dr. Bates already wrote. This body scanning is actually a modification of palming. I'm sure clever Dr. Bates was very well aware about this state of effortlessness, and that's why he started with palming with almost every patient. He could then take a look at the patient and clearly tell if the patient made it or not. That's the secret of his success. As I re-read the book again, the words resonate with my own experience with a new wave.
I keep exploring this state and feeling of effortlessness of the mind, how it can be brought about and what it depends on, and refining my skills. It's such an exciting adventure! :) I'm giving more trust to my body and intuition, and hoping it will bring me to the right path.
P.S. I'm going to change the format of this blog. Instead of lengthy posts that make it hard keep up regular posting, I'd rather write short thoughts and observations quickly as they come.

Reminders for Summer Eye Practice
By KATHLEEN E. HURTY
Miss Hurty distributed these instructions to her patients for use during the summer. These are the fundamentals of Dr. Bates' method and are important to bear in mind at all seasons.
Palming—Do this at least three times a day for not less than five minutes each time. Always palm a few minutes just before going to sleep.
In palming best results are obtained when the whole body is comfortable and relaxed. While palming let the imagination play with pleasant scenes and let your mind drift laxly. Never follow a definite train of thought.
Long Swing—Practice this as often as possible. Keep an easy, lazy, rhythmical motion. Things should appear to move in the opposite direction.
Snellen Card—Practice with the card at least twice daily, using the fine print, your memory of a letter, a short swing, blinking, etc., to help you see the letters on the card.
Sun—Let the sun shine on your closed eyelids for short intervals. Choose preferably the early morning sunlight. It is the light rays which benefit the eyes rather than the heat rays. The sun loses some of its effect when it comes through glass.
Blinking—Normal eyes blink constantly. If you have unconsciously formed the habit of staring, practice the quick blinking exercise in order to overcome this tendency. Practice it often.
General Directions—Try to see things moving all day long.
Never make an effort to focus. Let things come to you.
Do not make a task of your eyes exercises. Make a game out of improving your vision.
If you get a chance, teach someone else. It will help you.
Never let a feeling of strain continue. Stop and practice one of the methods of relaxation. Let me hear from you at least once during the summer.

Great Progress with the Universal Swing!
I discovered it by accident. I was in my country house doing some physical work, and I pulled a muscle in my back causing myself acute pain. That day I practiced a lot of long swing (swinging my head from side to side) and I decided to use it to try to alleviate the pain. To my surprise, the pain momentarily disappeared after just a few swings, and also I noticed at that moment my mind felt different, like if I suddenly woke up!
In few days after that I've been studying that state of the mind and I've learned that it's the universal swing that I've been looking for, and that now I am able to enter that state consciously! Not always, but often times I can, and these times are coming more and more often recently.
Here is what it feels like:
- I suddenly feel like I'm awake from "sleepiness". This is a kind of pseudo-sleepiness caused by stare, when the eyes want to close and roll up and you feel discomfort. This "sleepiness" can be taken to its extreme when one looks at the sun with stare. (That's why I think sun treatment is useful -- it demonstrates people what is stare, how it feels, and then how it feels when the stare is gone and replaced with the universal swing.) BTW, it seems that the association of the feeling of stare with "sleepiness" is pretty personal to me, other people do not seem to use the word "sleepiness".
- The entire world seems to be moving in slow, short and easy motion. Sometimes this motion is so subtle that it's almost unnoticeable.
- The entire vision becomes deeper, more vibrant and transparent
- The state is fueled by motion. When I move my head, even a small bit, my mind resonates to the movement and a new wave of awakeness and swing is produced.
- Photophobia goes away entirely. The eyes suddenly open up wide and blink freely, feeling very light and easy, no need to squint at the bright day. I can look at the sun at such moment, without any discomfort and scotomata.
- Flashes of improved vision follow in few seconds, unless I lose the swing.
- When the swing stops, the stare returns immediately. I realized there are only two states: stare and swing, there are no other states. The movement should never stop.
I learned how to enter the state using long swing. I sway my head from side to side for a few minutes, noticing how my shoulders, window frame and the entire world is moving in opposite direction. Recently I've been able to remember the universal swing with only a couple swings of my head. I keep going and swing my head from time to time pretty much all the time, like a Chinese statuette, checking if I still have the swing, and renewing it.
When I lose the swing, it always happens very surreptitiously, so it's easy to miss. It feels like you forget again what is universal swing, and fall into the unconscious sleep. It requires and will require much awareness from me not to lose the moment when it happens and to renew the swing to keep it permanent. But I think it's now just a matter of time to learn to do it under all conditions.
My vision has also greatly improved. In favorable conditions (sunny days which are plenty recently) I have lots of long-lasting flashes, some of them close to 20/20, all through the day.
P.S. My blog has been quite silent recently. That's because I am participating actively in a Russian-speaking community "TRUE BATES METHOD или как ПРАВИЛЬНО восстанавливать зрение по Бейтсу".

Seeing the Sun in the Deep Sky
And I have discovered a beautiful thing I'd like to share. Usually at the beginning of sun-gazing, it's hard to look at the sky and the sun, without squinting and blinking too frequently and hardly. Also I often have attacks of sudden sleepiness that forcefully shuts my eyelids and rolls up my eyes. I already know these are symptoms of mental strain. I keep sitting in the sun rays doing nothing, just relaxing and enjoying. Suddenly it feels like a fresh breeze touches my face and I become fully awake. I open my eyes easily and widely, no longer feeling the urge to blink, and see the sun with perfect comfort and joy. The entire sky appears different. It becomes so deep and so blue, and the air seems so clear. When there are white clouds or a tree branch in the field of view, they appear unusually deep, three-dimensional and clear. I also notice the universal swing. This state lasts for few seconds, 5-10. Then I have the attacks of strain again, but they tend to be shorter and less with each time. Needless to say that my sight is greatly improved after this sun-gazing, temporarily.
I hope I have found the right way of sun-gazing. Or at least the right result of it. I think this is what Rishi meant when he said he could sun-gaze without discomfort for 45 seconds and more. At that time I was confused to hear it, because I could spend much more time in the sun, without scotomata. But this "full depth" state really lasts only few seconds, and I will be looking to make it longer.
Routine Failure
Because the routine failed, for a couple of weeks afterward I tried doing the opposite -- did not practice at all and watched myself. My vision did not worsen and at the beginning was even better than at the end of the routine month. So, the other lesson I have learned was that one should continuously change and try different things, as soon as the previous things stop working. Boredom and tiredness are forms of strain.
The best environment for successful practice, at least for me, appears when I know that I don't have to do anything "Bates", and there are no limits in time. I can do it just for fun to explore how my mind works, or just to entertain myself.

"Practice Time": The Routine of the Bates Method Given by Dr. Bates Himself!
Practice Time
A large number of people have bought the book "Perfect Sight Without Glasses" but do not derive as much benefit from it as they should because they do not know how long they should practice.
Rest: The eyes are rested in various ways. One of the best methods is to close the eyes for half an hour after testing the sight. This usually improves the vision.
Palming: With the eyes closed and covered with the palms of both hands the vision is usually benefited. The patient should do this five minutes hourly.
Shifting: The patient looks from one side of the room to the other, alternately resting the eyes. This may be done three times daily for half an hour at a time. The head should move with the eyes and the patient should blink.
Swinging: When the shifting is slow, stationary objects appear to move from side to side. This should be observed whenever the head and eyes move.
Long Swing: Nearly all persons should practice the long swing one hundred times daily.
Memory: When the vision is perfect, it is impossible for the memory to be imperfect. One can improve the memory by alternately remembering a letter with the eyes open and closed. This should be practiced for half an hour twice daily.
Imagination: It has been frequently demonstrated and published in this magazine that the vision is only what we imagine it to be. Imagination should be practiced whenever the vision is tested. Imagine a known letter with the eyes open and with the eyes closed. This should be practiced for ten minutes twice daily.
Repetition: When one method is found which improves the vision more than any other method, it should be practiced until the vision is continuously improved.

How I Enter the State of the Universal Swing
Nothing Is Straining, Nothing Is Relaxing
Two Years of Bates Practice
The Cause of Scotoma
Update: I no longer practice and/or recommend sun gazing with opened eyes, because there are much less intrusive techniques of relaxation in the Bates method, and the risk of acquiring additional strain and scotomas during sun gazing is simply not justified. Exposing your eyes with closed eyelids to direct sun is enough. Just take care to cover your face to protect your skin from sun burns and premature forming of wrinkles, don't do it in the middle of summer day, don't do it for more than 5-15 minutes. Also you can use powerful (~1000 lumens) LED flashlights on your closed eyes with nearly the same effect but without the risk of a UV burn.

The Wrongest Idea about Eyesight
Wednesday, May 28, 2008
The Best Bates Teacher in the World
People who teach Bates method may be wrong. They may be just earning their living by telling you things that resemble Bates method but actually are against it. They may have been taught by wrong people too. They may not even have perfect sight. There is no guarantee that they completely understand the fundamental principles set forth by Dr. Bates. The reality is that most of them do not.
But even if you find a good teacher, he or she won't tell you the feelings and experiences of your own mind and body you should look for. Human language is just not capable to carry such things. So, the best you can get from a human teacher is just encouragement and a guard from obvious blunders.
The sun is totally different. The sun punishes you immediately with the intolerable discomfort, afterimages and other ill effects when you treat it in the wrong and strained way. And it encourages you with pleasant comfort and improved vision when you find the right way. All this happens directly in your mind, without mediation of words. I often thought that if I only could have a perfect indicator of strain, I would cure myself very quickly. I have finally found it. The discomfort from bright light is a direct manifestation of strain. It IS strain, in a sense.
The next step I have found is a fun game of provoking more discomfort when you reach a certain level of comfort in the bright light. For example, I look at the sky near the sun and notice the sun is seen worse in the eccentric field, look to the earth than back to the sun, swing the sun etc. This all usually breaks my balance, I begin straining and a wave of discomfort returns. Then I dissolve it again, and my comfortable relaxation becomes deeper and more stable.
After successfully learning to obtain comfort in bright light, I began to notice the same discomfort as from looking at the sun with strain, in many other situations, when there is no bright light. It's just too subtle, and that's why I wasn't able to notice it before the sun amplified it hundred times. Now when I am able to sense the discomfort in other situations, I can also apply the same techniques that I use to get accustomed to the bright light. The results are very encouraging.
Right Words and Wrong Words
Because vision problems are entirely in the mind, it is important to be careful with words, because the ideas behind them may be wrong and thereby retard the cure of imperfect sight. Dr. Bates was EXTREMELY careful with words. Every his word is a gem. I tried to translate Dr. Bates' texts to other languages and I tell you it's very difficult to do so without losing part of the meaning, or using too much words to deliver the full meaning. English is the perfect language for Bates method.
Here is the list of words that Dr. Bates didn't use, and I avoid using myself, in context of eyesight and Bates method:
WRONG: sunning, solarization
RIGHT: sun treatment, sun gazing
WRONG: centralization (I would kill for that! :) )
RIGHT: central fixation
WRONG: clear flash
RIGHT: a flash of improved vision, a flash of perfect vision
There may be others that I will remember and post later
Also, I'd recommend to avoid the following words:
to focus, to concentrate, to try hard, to do my best, to make an effort
And of course stay away from the following optician's words, because the phenomenons meant by them are non-existent but have been brought into your mind by compulsion:
prescription, diopter, myopia, astigmatism, hypermetropia etc.

Imperfect Sight Is Mostly an Illusion
It is however accepted even by the optometrists that eyesight cannot be measured in diopters, as it should have been if imperfect sight was really strictly due to eyeball deformation. That's why the Snellen card X/Y numbers are used, meaning that two persons with the same Snellen reading without glasses may require different glasses for the same correction. Consequently, there's something else that contributes to imperfect sight than eyeball deformation, and it is the illusions caused by mental strain.
It took me quite a long time to demonstrate myself this fact. I learned it from my flashes of improved vision. When a flash occurs, the image does not gradually reduce the blur to the point when it fully converges, as it would be for a focusing camera. During the flash, first a multitude of sharp double-images appear out of the blur, surrounded with a cloud of blur. Then the images line up horizontally. Next, most of the images fade out and only two stay, on quite a big distance from each other, one more vivid than the other. At this point, the fog of blur disappears and the two images appears amazingly clear and three-dimensional. Finally, the less vivid image gradually fades out and the perfect sight arrives. What a weird play of mental illusions! You will never obtain this with just optical systems. I believe my eyeballs come into the right shape quite early, when I begin to see the multiple sharp images, and the rest of time I am observing only mental illusions, when I could already have perfect sight.
The conclusion is: stop trying to do something with your eyes. Switch entirely to practicing with your mind. Don't underestimate memory and imagination techniques.
Sun-Gazing Experience
Previously, I was only able to look at the sun without discomfort for a few seconds, then the wave of sleepiness and discomfort returned and I had to look away or close my eyes. This time it was different. By using the burning glass, doing long swing with my eyes up to the sky and getting accustomed to the sky near the sun, in about 10-15 minutes I became able to look at the sun, anywhere at the sky near the sun, and anywhere on earth and then back onto the sun, without losing the comfort and without any afterimages or color changes. I blinked at the normal rate. I even saw the edges of the sun sharp for few moments, although as a rule I see sun in blur. (so, obviously my sun gazing is still not perfect and I still have room to develop). The sun was swinging slowly and I was able to easily remember the swinging black period.
Because I was a bit bewildered with the fact that I no longer have to fight discomfort, I didn't know what to do next :) and decided this time to take a longer session of sun gazing than I normally do. The same day I had unusually sharp flashes of improved vision whenever I looked to the window. The next day the weather was overcast and I had a bad relapse, one like I haven't had for a long time already. I couldn't look even at the clouds without discomfort, and nothing seemed to give me relief. It is however known that relapses often take place the next day after sun gazing, but after they go, the eyesight improves further. Now it's the third day and the relapse is gone, and my vision feels like somewhere on the edge of a flash all the time. I am very intrigued with the power of more lengthy sun treatment, when I am comfortable with it, and look forward to try it again. To be honest, previously I was afraid to try it because of my first bad experience of sun treatment, when I did it wrong and developed a scotoma that lasted for two months.

Universal Swing and Variable Swing
Looking to reproduce this feeling after few attempts I have found, guess what, that it is the same thing that is described by Dr. Bates as "universal swing" and "variable swing". It feels like realizing that the space is not flat and objects are located in different planes. Even if you can't see the detail, you can always see that objects change their relative positions to each other as you move your body, head or eyes. The easiest it is to notice when doing the long swing. Then, you can make the movement shorter and still notice that the perspective on objects slightly changes. You can also remember this feeling with the eyes closed.
An important point is that you do not pay attention to the blur and not try to clear it away, but instead only pay attention to the swing.
When successful, the strain decreases so that I become able to stop physically moving my head and then keep the swing purely imaginary. It is slow and short, as it should be.
If I am aware of the universal swing for long enough - a couple of minutes, my eyesight improves automatically. So I now remember to practice it all the time. It is easy when you walk outdoors. The challenge is however to practice it while working at the computer screen or book, where the view field is mostly flat.
