farsightedness or in medical terminology, hyperopia is a type of refractive eye.When farsighted focus optics of the human eye is beyond the retina.That is, parallel rays emanating from objects in the field of view, converge behind the retina.The cause of hyperopia is a weak refractive power of the optical media of the eye.It may also be due to the small length of the eyeball.
farsightedness in children at an early age - this is quite normal.Kids are born with hyperopia eyeballs.Therefore, far-sightedness in children under one year of 2-4 diopter is not a violation, and should not cause undue concern.
farsightedness in children up to three years, according to the Medical Research found more than 90% of cases.As a rule, it remains at an early age, gradually decreasing in the direction of the normal eye refraction, and 1 diopter to school age.There is a change because the eyeball baby grows.However, there are cases when long-sightedness in children is still evident, the reason for this may be a delay of growth of the eyeball.Children having this optical defect, have to strain your eyes.Since in order to see well and have a clear image of objects, you need a constant voltage of accommodation.At first, the baby's eyes, as it were adjusted to compensate for the existing slight degree of farsightedness.But in the future this may lead to various eye diseases, for example, often such "compensation" turns spasm of accommodation (prolonged overstrain ocular muscles).In addition, it may lead to the appearance of strabismus in children.
Based on the degree of deviation from the normal state of the optical system of the eye,
sightedness in children can be divided into three types:
- weak hyperopia up to 2 diopters
- average - up to 5 diopters
- and high hyperopia, more than 5 diopters
reveal the degree of impairment and to conduct proper diagnosis is possible only by means of special medical examinations.In order to prevent, we advise you not to neglect a visit to an ophthalmologist at least once a year.This will help you quickly identify visual impairment and to develop the right method of treatment.Children may not themselves determine that they have a visual impairment.Therefore it is very important to get regular check-ups by a specialist.As the symptoms that can point out to you that your child may develop long-sightedness, are the following.Kid after visual work may complain of eye pain, headache.When reading the child gets tired quickly, experiencing visual discomfort, perhaps even may become irritable, and, of course, there is a loss of vision.
If your child is identified farsightedness, correction of this disorder may have a few options.
At preschool age recommend the use of positive lenses for the correction of even a small degree of farsightedness.Children older than 7 years, the doctor prescribes glasses with collecting lenses or contact lenses.If the degree of farsightedness is weak, then wear glasses should be only at long visual work, such as reading the lessons at school, homework.If in addition to the development of far-sightedness, the child has a squint, is appointed full optical correction of the visual system.Of course, the sooner you will be able to identify violations of the visual device of your child and start the appropriate treatment, the better the chances to prevent complications.
