Myths about vision: nothing worth believing

 Myths about vision: nothing worth believing  There is a genetic susceptibility to eye diseases, although some diseases can also affect the health of your eyes.


Myth 1: The old vision of the port is not at all


Eye - optical system that allows you to focus images on the retina. Through the pupil light beam hits the lens, which acts as a lens and flattening or thickening transmits an image on the retina.


Over the years, the muscles of the lens become less elastic, the lens hardens, almost ceases to thicken, and we're starting to see bad close. Make the lens more flexible by exercises for the eyes possible. It is an irreversible process, and presbyopia (age farsightedness) threatened all people without exception.


Myth 2. Myopia in children arises from the load at school


In a normal eye has a spherical shape, and is projected on the retina clear picture. In myopic child's eyeball is more elongated, and the picture is not projected on the retina. The image projected on the retina severely, kids have to hold the book close to his eyes and lean over it. When the child grows, the eyeball is too varies in size and myopia progression. To load the eye myopia has nothing, is a hereditary disease.


Myopic child needs to wear glasses, so he formed the ability to perceive the image correctly. And to do exercises to strengthen the eye muscles.


When the child grows up, stops the growth of the eyeball, and you can make a simple vision correction surgery. But if nearsighted child will not wear glasses, his brain did not learn to see the world clearly, and the operation will not help.


Myth 3. Eye diseases are inherited


There is a genetic susceptibility to eye diseases, although some diseases can also affect the health of your eyes.


In particular, diabetes and atherosclerosis - causes of glaucoma. Normally inside the eye contains aqueous humor, which constantly flows off and is absorbed into the blood vessels. If a person has diabetes, atherosclerosis, high blood cholesterol level, the outflow of intraocular fluid is disturbed. Intraocular pressure increases, squeezes the optic nerve, which may lead to blindness. And this occurs without symptoms, you do not even feel it.


People with diabetes, atherosclerosis, obesity, as well as all who are over 50, every year should measure your intraocular pressure, monitor the level of sugar and cholesterol in the blood.


Practising eye muscles

With this simple charging train muscles, making the lens convex or flat.


1. Become the window. Close one eye hand. The second eye locate the subject beyond the window.


2. Move the view from a distant targets on pre-painted dot on the glass window. Again, look at the target distance.


3. Repeat the exercise 10 times. It is best to do this complex several times a day - the time it does not take a lot, but the benefits will be tangible.
