Every day we meet people who could not help push the book out of sight.It is possible that over time, and we ourselves become also come.It speaks of such eye diseases as farsightedness.Farsightedness or hyperopia is a vision defect, which is as far back as the fifteenth century glasses owe their existence.It was then with the advent of printing was the first person to notice that near spreads, it is easier to distinguish between letters, if they are at a distance.It was then that were invented by removing special glasses.Interestingly, for myopic lenses were only a hundred years.

farsightedness reason lies in the violation of refractive eye when the image is formed behind the retina.Usually eye axis is shortened, less than twenty-three and a half millimeters, or the fact that the refractive power of the cornea is weak.

Usually patients suffering from hyperopia, a doctor does not treat, especially if the disease is mild degree.Often in this case, vision hardly broken.The only thing that worr

ied man - a headache at long visual loading.When the average degree of farsightedness person sees something that is far from good, but near vision is difficult.The high degree of hyperopia is characterized by the fact that the bad man sees how far or close, because the eyes have been exhausted completely.

reasons farsightedness

Experts identifyonly two possible reasons for hyperopia, but in some cases a combination of both mentioned reasons.Farsightedness can occur with shortened eyeball or in the event that the optical system of the eye refractive power is insufficient.In the first case, often there is a family history - such farsightedness is transmitted genetically.In the second case, the eye lens refracting ability weakens over the years, so this type of hyperopia usually occurs in people over forty, forty-five years, and is driven, usually age-related changes in an organism.This is also called senile hyperopia.

hyperopia Symptoms Symptoms

farsightedness apparent - poor people see near, but when considering distant objects, depending on the degree of farsightedness, people may see them as clear and blurry.At a young age the lens of the eye is able to adapt to and accommodate the resources of the eye in order to increase the optical power.At older ages, this is not possible, because the resources are gradually exhausted eyes, therefore, hyperopia symptoms progress.

In addition, the symptoms of hyperopia include eyestrain when reading, as well as overvoltage during their long hours of work.In addition, the eyes of people suffering from hyperopia often inflamed, and the children can develop a squint and a symptom of the so-called "lazy eye."

Based hyperopia symptoms are classified by severity.Weak sightedness - is to +2 diopters, farsightedness average - it's up to +5 diopters, farsightedness and strong - more than 5 diopters.

disease is difficult, it may manifest in childhood symptoms uncharacteristic of eye diseases.This symptoms such as fatigue, moods, reluctant homework, and sleep disorders.Such asthenic complaints point to eyestrain, visual apparatus.If you pay attention to it and farsightedness diagnosed at an early stage, it is possible to avoid complications such as lazy eye syndrome, or amblyopia, strabismus, violations of the outflow of intraocular fluid, raising the intraocular pressure and glaucoma.

With the emergence of the earliest symptoms of hyperopia can not be ignored, ride the disease, because the complications that result from hyperopia, can be very unpleasant and dangerous.

As soon as you notice that the worse began to see those items that are located near, immediately consult an eye specialist.You need to check visual acuity on a special table.Expert examines the fundus, will ultrasonography.With phoropter you to pick up the individual lenses.Keep in mind that the usual routine inspection of hyperopia can not be identified, as well as can not be established and its degree.So do not be complacent, if not a regular medical examination the doctor said you departures: if you feel that you have become less visible, - consult your doctor.

correction of farsightedness include, above all, the correct selection of glasses and contact lenses.The ophthalmologist will advise you how to properly train the muscles that are responsible for the accommodation of the eye.Usually, in the range of coaching activities they include laser stimulation, special gymnastics courses, instillation of drugs in the eye, as well as computer vision correction.All these activities should be carried out only under the supervision of the attending physician.

recommended actions restorative - a contrast shower or swimming, as well as a balanced diet, which are present in the right proportions protein, vitamins and trace elements zinc, iron, magnesium.

farsightedness correction is carried out by means of glasses, contact lenses and laser correction.Points are distributed mainly on the territory of our country, while the West has been using contact lenses and glasses are used only for vision correction in children.Contact lenses in this sense it is more convenient, but get used to it is far from all.Also, wearing lenses danger of allergic reactions.For adults over the age of eighteen years, modern medicine offers laser correction of hyperopia, which has consistently achieves amazing results.When choosing a method of eye doctor takes into account all the features of your vision, its flow and calculates the possible risks.For this reason alone it is not recommended to choose the methods of correction without the participation of a physician.
