Kurdish sighs, which is a common optical disease, where those can see things nearly near, while the distant things look vague. It occurs when the shape of the eye, or rather the shape of certain parts of it, causes an inaccurate light light, as light rays that should focus on nerve in the back of the eye (retina) are concentrated before the retina. The palace usually appears during the child and adolescence phases, and then it usually becomes more stable between the ages of twenty and forty years. A basic examination of the eye can emphasize the extent of short visibility. You can compensate a foggy vision using medical glasses, adhesive lenses or a break operation. Symptoms of vision -shortage may include the indications and symptoms of myopia: confusion of vision as you look at distant things. The need to close the eyes, or partially apply the eyelids to see clearly. Headache. Eye tension. Children may find it difficult to see things on the whiteboard, or display screens in the classroom. However, younger children cannot see their trouble to see, but they can take on the following behavior that indicates the problems of vision: They constantly close their eyes. They do not seem to realize the presence of far things. They throw their eyes excessively. They save their eyes a lot. They sit near TV. Regular investigation tips can be ignorant of children and adults, the presence of problems or changes in their vision gradually, so the American Academy of Eyaway regularly recommends to make eye exams to ensure a timely diagnosis and treatment. The causes of myopia. Your eyes contain two parts that focus images: the cornea: it is the transparent front surface of your eyes and takes the shape of the dome. The lens: It is a transparent body in the size of the MD and EMS Candy Grain and its shape. In order to see, light rays must go through both cornea and lens, and these two molecules (breaks) light radiation, and thus light radiation is concentrated directly on the nerve tissues (retinal) in the back, and then this light radiation tissue is in signals sent to the brain, enabling you to observe images. Disorges are a breakdown error, and this problem occurs when the shape or state of the cornea – or the shape of the eye itself – leads to an inaccurate light concentration, and then the light goes to the eye. The nearby is usually caused by the excessive length of the eye, or it takes an oval shape, not circular. This can also happen due to the severe calibration of the cornea. These changes lead to light rays to a certain point before the retina and their passage to the eye. The messages sent from the retina to the brain are therefore considered fog and confused. Another refraction errors include the following: Sig (visual expansion): It occurs when the eyeball is shorter than normal, or if the corneal conventional is less than it is. Some people may see somewhat far things, while the nearby things look confused when they see them. Some people who have neglected are vague when they see them from all distances. Departure: It occurs when the cornea or lens concept is more about the direction more than the others. The vision looks confused or vague from all distances. Diagnosis of myopia is diagnosed with a prerequisite with a basic examination of the eyes. The ophthalmologist will probably ask you about the satisfying history for you, or for your child, and for any medication he takes. Treatment of myopia focuses the usual target to treat myopia on improving vision by helping to focus light on the retina by using corrective lenses or refraction operations. Methods of concession also include periodic follow -up to detect the complications of the disease, such as blue water, eye lens and retinal separation. Medical described lenses treat corrective lenses by adjusting almost visibility by adjusting the excess corneal curvature or the excessive length of the eye. Types of lenses described medically include: The medical glasses are a simple and safe way to sharpen the vision by treating their imbalance due to the vision. Lenses of eye glasses can also be designed to correct a set of refraction errors, such as visual brevity, departure from vision and aging vision. Contact lenses are small plastic tablets that are placed directly on the cornea. A single adhesive lens can be more correct than a breakdown error. These lenses are made of different materials and have different care requirements. An eye specialist may recommend using contact lenses that best suits the prescribed medication for you and your lifestyle. Occupational surgery reduces the refraction surgery of the need to use glasses and contact lenses. Laser -eye surgeon is used to form the cornea, thus reducing the need to carry the vision of short lenses prescribed by the doctor. It should be noted that the patient may have to use medical glasses for some time, even after surgery. Correct corneals in place with laser assistance in this medical procedure, the ophthalmologist is made with a thin, moving increase within your presidency. Then the laser is used to remove some corneal tissues to flatten the curved shape. Usually, the recovery of the local corneal correction surgery is faster and less disturbing to the patient than other corneal operations. The cornea pulls off under the epithelium with laser help (Lasek) only makes a very thin eye surgeon in the outer lid (epithelium) in the corneal. Then the laser is used to reform the cornea to flatten its siphon and then apply the epithelium to its place again. The laser cornea (PRK) is similar to this medical procedure to subtract the cornea under the epithelium using the laser, except that the surgeon removes the external protection cover for the entire cornea and then uses the laser to form the cornea. The cornea is covered with a protective adhesive that is temporarily placed until the epithelium forms formally, in accordance with the form of your new angle. Smile’s nominal removal does not make the surgeon in this medical procedure, that is, nor remove the epithelium. But it rather uses the laser to cut a small part in the form of a tablet (an enlarged) of the cornea, then this part is then removed by a small incision in the cornea. It should be noted that surgical procedures are not a suitable option for anyone injured. But it is recommended to use only a surgery in the event that the sight level does not decline, and its stability on a certain limit. The ophthalmology will show you the benefits of each surgical treatment option. By satisfying the nobles, researchers and clinical experiences are still seeking more effective ways to delay the progress of the warning in children and adolescents. The most important promising treatments include the following: Atropine usually uses the atropine drops to expand the pupils, as part of the eye examination, or before and after eye surgery. Low doses of Erubin drops of the eye can help slow the progress of the bee. If you spend more time abroad, it can reduce time abroad during childhood, adolescence and early adulthood years of a risk of short -term visibility. Contact lenses with dual concentration are a type of contact lens that has shown that it has an effect to delay the progress of myopia. Correct corneal correction where a solid adhesive can be placed during the night for a temporary period for the purpose of reforming the cornea. This lens is not meant to wear during the day. Studies have shown that this treatment can delay the progress of the booth. This content of Mayo Clinic.
