The four most common eye disorders, or "refractive errors" are nearsightedness, farsightedness, astigmatism and presbyopia. They are not diseases, but simply minor flaws in the construction of the eyes. The human eye reaches its adult size and shape when a person reaches their twenties. At that time, myopia, astigmatism and, eyeglasses, farsightedness usually stabilize. Nearsightedness, known scientifically as myopia, a person close objects clearly see distant objects. This does not mean that a nearsighted person has a near vision and poor distance vision excellent. The extremely short-sighted people can not see anything clearly. In the normal eye, parallel rays of light through the cornea and then bend slightly bend when they enter the objective of focusing on a small site in the retina. In the myopic eye, a highly curved cornea or elongated eye, or both, of the light rays focus before reaching the retina. From this focus, eyeglasses, of light rays start to diverge. At the time the light reaches the retina, the image is blurred. Vision, known as vision, is the opposite of myopia. It is not necessarily the ability to see objects clearly at a distance and close-up of the poor, although this may be the case. In the hyperopic eye, light rays coming through the cornea and lens before reaching the retina at the photo, causing a blurred image. In a way, the eyeball is too short for the refractive power of its own optical system. Sometimes people look mild refractive error is not discovered until middle age, they begin to have trouble seeing clearly at close range. This explains the common need for reading glasses among our people in middle age. An astigmatic eye cornea due to malfunctioning. The cornea of the eye astigmatism can be bad inclined from top to bottom or left to right. This error shows the design of several refractory corneal powers over its entire length and width and sight disturbing. Some focus on the light rays in front of the retina and others behind. As a result, the retina never get a single clear image. Presbyopia is an optical illusion that eventually affects nearly everyone. As eyes age, the powers of the housing decline. It is increasingly difficult to see close objects in sight. A person with presbyopia can be sighted, myopia or astigmatism at the same time. If this is the case, can give extra help with bifocal eyes on nearby objects, no matter what other errors of refraction in the eye may have. By M Adley http://www.eyes-and-vision.com

My mother took me to the optometrist when he was 8 years old. I do not know why he was there or what it was all. The optometrist in this strange machine target for my eyes and I had to read the letters on the screen. The study was not long and one weeks later I returned and gave me the glasses optometrist to use. I did not like at all. My eyes and vision is felt strange, disoriented and waist. But I brought home. Na, I never wore my glasses, but my mother told me at home. But outside of my house, away from my mother, my glasses in the case of my pocket and did not use them. I do not need glasses. All I could see perfectly without glasses. Perhaps I looked a little when I looked at the school board, but that was all. I did not like the glasses, I need not, and never took them away from my mother. But soon after my teacher sent me to the school nurse and she told me to wear glasses all the time. I've worn glasses since then – all day every day for over 30 years. I'm sure you do not need glasses in the beginning. I was much better before you start to wear what I saw after wearing glasses. What happened? After glasses for a while I could not do anything without my glasses, totally dependent on glasses. Without my glasses I could not see clearly beyond 15 meters. The world was a complete blur. I could not function without glasses. I could not drive my car without my glasses. I could not see the letters on street signs without the glasses. I could see written on the board without my glasses. I could not participate in sports without my glasses. I could not watch TV without glasses. Most disturbing, without my glasses, I could see the faces of people of all. I could see that the human form quite well, but the face was completely blank as a fuzzy spot on the face. I was totally dependent on glasses and my eyes were getting worse all the time. One eye was much weaker than the other eye. I had night blindness. I saw halos around lights and stripes he was deeply concerned about my eyesight is deteriorating. When I arrived all was optometrist. He looked at my eyes, gave me a stronger prescription glasses and sent me on my way without much to say. All research was conducted in almost total silence. The optometrist gave no explanation of what he did and why. Everything was fine. The sun was shining, the birds sang as they took me by the garden path to blindness. There was something wrong. I was blind and the optometrist was not involved at all – incredible. What kind of medical treatment is this? I'm supposed to be better, not worse. The main problem is that optometrists believe that vision problems can not be prevented or cured. They believe that in addition to glasses, contact lenses or laser surgery, nothing can be done to focusing errors in the eye to correct. We say, "You must wear goggles for the rest of his life." Optometrists do not have vision loss prevention program. If your eyes worse, that only require stronger prescription glasses and oversee the development of eye diseases such as cataracts, glaucoma and macular degeneration, then wash their hands for you and send you an ophthalmologist. For normal health, doctors prescribe: exercise, eat well, watch your weight, avoid stress, not smoking, limiting alcohol, get eight hours of sleep, various, eyeglasses, physical therapies, and a healthy lifestyle. These are also good for the eyes. Doctors acknowledge that the body can heal itself. Our eyes can heal itself, like the, eyeglasses, rest of our body.
