Are Glasses or Contacts destroying your vision?
Few optometrists will admit and the greatest majority are unaware that glasses and contacts are almost guaranteed to destroy your eyesight over time. Unfortunately, they’re not trained on natural and preventative solutions that improve vision in the long-term because they simply do not understand the way the eye works. Contrary to popular belief, your vision doesn’t have to decline over time. With regular exercise of the muscles that control your eye movements and visual acuity, you can reduce eyestrain and maintain or even improve your vision without any destructive correctional conventions such as laser surgery, glasses or contact lenses.
Most writers on ophthalmology appear to believe that the last word about problems of refraction has been spoken, and from their viewpoint the last word is a very depressing one. Practically everyone in these days suffers from some form of refractive error. Yet we are told that for these ills, which are not only so inconvenient, but often so distressing and dangerous, there is not only no cure, and no palliatives save those optic crutches known as eyeglasses or contacts, but, under modern conditions of life, practically no prevention.
The Primal need for distant vision
With one accord ophthalmologists tell us that the visual organ of man was never intended for the uses to which it is now put. Eons before there were any schools or printing presses, electric lights or moving pictures, its evolution was complete. In those days it served the needs of the human animal perfectly. Man was a hunter, a herdsman, a farmer, a fighter. He needed, we are told, mainly distant vision; and since the eye at rest is adjusted for distant vision, sight is supposed to have been ordinarily as passive as the perception of sound, requiring no muscular action whatever. Near vision, it is assumed, was the exception, necessitating a muscular adjustment of such short duration that it was accomplished without placing any appreciable burden upon the mechanism of accommodation.
While primitive man appears to have suffered little from defects of vision, it is safe to say that of persons over twenty-one living under civilized conditions nine out of every ten have imperfect sight, and as the age increases the proportion increases, until at forty it is almost impossible to find a person free from visual defects. Voluminous statistics are available to prove these assertions.
What Glasses and Contacts Do To Us
All glasses contract the field of vision to a greater or less degree.
Perception of Color:
The fact that glasses or contact lenses cannot improve sight to normal can be very simply demonstrated by looking at any color through a strong convex or concave glass. It will be noted that the color is always less intense than when seen with the naked eye; and since the perception of form depends upon the perception of color, it follows that both color and form must be less distinctly seen with glasses than without them. Even plane glass lowers the vision both for color and form, as everyone knows who has ever looked out of a window. Women who wear glasses for minor defects of vision often observe that they are made more or less color-blind by them, and in a shop one may note that they remove them when they want to match samples. If the sight is seriously defective, the color may be seen better with glasses than without them. That glasses or contact lenses must injure the eye is evident from the facts given in the preceding chapter.
One cannot see through them unless one produces the degree of refractive error which they are designed to correct. But refractive errors, in the eye which is left to itself, are never constant. If one secures good vision by the aid of concave, or convex, or astigmatic lenses, therefore, it means that one is maintaining constantly a degree of refractive error which otherwise would not be maintained constantly. It is only to be expected that this should make the condition worse, and it is a matter of common experience that it does. After people once begin to wear glasses their strength, in most cases, has to be steadily increased in order to maintain the degree of visual acuity secured by the aid of the first pair.
Ruining proper vision:
Persons with presbyopia who put on glasses because they cannot read fine print too often find that after they have worn them for a time they cannot, without their aid, read the larger print that was perfectly plain to them before. A person with myopia of 20/70 who puts on glasses giving him a vision of 20/20 may find that in a week’s time his unaided vision has declined to 20/200, and we have the testimony of Dr. Sidler-Huguenin, of Zurich that of the thousands of myopes treated by him the majority grew steadily worse, in spite of all the skill he could apply to the fitting of glasses for them. When people break their glasses and go without them for a week or two, they frequently observe that their sight has improved. As a matter of fact the sight always improves, to a greater or less degree, when glasses are discarded, although the fact may not always be noted.
That the human eye resents glasses is a fact which no one would attempt to deny. Every oculist knows that patients have to “get used” to them, and that sometimes they never succeed in doing so. Patients with high degrees of myopia and hypermetropia have great difficulty in accustoming themselves to the full correction, and often are never able to do so. The strong concave glasses required by myopes of high degree make all objects seem much smaller than they really are, while convex glasses enlarge them. – These are unpleasantnesses that cannot be overcome.
Patients with high degrees of astigmatism suffer some very disagreeable sensations when they first put on glasses, for which reason they are warned by one of the “Conservation of Vision” leaflets published by the Council on Health and Public Instruction of the American Medical Association to “get used to them at home before venturing where a misstep might cause a serious accident.” Usually these difficulties are overcome, but often they are not, and it sometimes happens that those who get on fairly well with their glasses in the daytime never succeeded in getting used to them at night.
Even with very weak glasses patients are unable to see distinctly unless they look through the center of the lenses with the frames at right angles to the line of vision and not only are their vision lowered if they fail to do this, but annoying nervous symptoms, such as dizziness and headache, are sometimes produced. Therefore they are unable to turn their eyes freely in different directions. It is true that glasses are now ground in such a way that it is theoretically possible to look through them at any angle, but practically they seldom accomplish the desired result.
How To Keep Your Eyes Naturally Healthy
Perhaps the single greatest reason why people in today’s society suffer from chronic eyestrain and deteriorating vision is the amount of time that is spent staring at computer monitors and television screens. Your eyes are designed to move regularly. Frequent movement of your eyes is what promotes optimal blood flow and nerve tone to your eyes and the six muscles that control your eye movements.
What follows are several simple eye exercises that you can do on a regular basis to keep your eyes and vision as healthy as possible:
– Look as far to your right as possible for 3-5 seconds, then as far to your left as possible for 3-5 seconds. Rest for a few seconds, then repeat this sequence several times.
– Look as far up as possible for 3-5 seconds, then look as far down as possible for 3-5 seconds. Rest for a few seconds, then repeat this sequence several times.
– Slowly roll your eyes in a circle, first clockwise, then counter-clockwise. Rest for a few seconds, then repeat this sequence several times. Be sure to roll slowly – it should take at least 3 seconds for you to roll your eyes in a full circle.
– Hold a pen in front of you, about an arm’s length away. Focus your vision on the tip of your pen for 3-5 seconds, then shift the focus of your vision to an object that is farther away for 3-5 seconds. The greater the distance between your pen and the distant object, the better. If you are indoors, look out a window to find a distant object to focus your vision on. Repeat this sequence of going back and forth between your pen and a distant object several times.
– Just for interest’s sake, this exercise is used by some professional baseball players to optimize visual acuity, which is essential for the hand-eye coordination that is needed to play pro ball.
Please note that all of these exercises should be done with your eyes, not your head and neck. With this in mind, keep your head and neck still while you take your eyes through the movements described above.
Relearning to See: Improve Your Eyesight
Naturally! is an outstanding book that offers a comprehensive array of exercises and information that can help you support your vision. And if you wear eyeglasses or contacts, following the guidance provided in this book may actually help you do away with your prescription eye wear or at the very least, help prevent deterioration of your visual acuity as you age.
Beyond doing the exercises described above on a regular basis, another way to reduce eyestrain and promote your best vision is to use your fingers to apply gentle pressure to three acupressure points that can help promote healthy blood flow to your eyes and the muscles that surround your eyes.
