Age-related farsightedness: causes and treatment
Age-related farsightedness or presbyopia develops in every elderly person. This is because the lens forms various sclerotic changes, in the process of development of which the ocular nucleus thickens, provoking a violation of accommodation. Accomodation is called the ability of the eyeball to strengthen the refraction of light rays, when the view is translated from distant objects to those that are located near.
A normal accommodation process makes it possible to clearly see both near and distant objects. When senile hyperopia starts its progression, the person notices that the outlines of closely located objects become as if slightly blurred. After a certain time, hyperopia increases and sooner or later there comes a time when a person with great difficulty can distinguish an inscription in a book or newspaper at a short distance from the eyes.
Symptoms of the disease
Hyperopia is considered a common pathology, which affects one in two people on earth after 30 years to some extent.
As a rule, hyperopia is formed due to systematic overstrain in the muscles, therefore, the main symptoms of the disease should include headache and rapid visual fatigue. In the formation of hyperopia, the eyes quickly become tired during reading, and the patient feels a burning sensation in the eyes. With prolonged examination of objects near the eyes, tingling and tearing may occur. Another symptom of eye damage is intolerance to bright light.
Farsightedness is classified into three degrees of severity:
- Weak degree.
- Average degree.
- High degree.
The weak degree of farsightedness is characterized by the normal operation of the visual organs, thanks to the accommodation process. With the development of medium or high farsightedness, both near and far distance vision deteriorates.
The main manifestations of pathology, in which the treatment of hyperopia in adults, are:
- Difficult discrimination of small items.
- Reducing the contrast of vision while reading text written in small print.
- To read the text, it is necessary to position it at a great distance from the eyes.
- The manifestation of tension and rapid fatigue of the eyes from reading.
- There is a need to read in bright and direct light.
In people with a congenital form of hyperopia, the work of the visual organs worsens with age, both in the distance and in the distance, and in patients with myopia the process of pathology development remains practically unnoticed.
The process of treating hyperopia
Correction of hyperopia largely correlates not only with the state of the visual organs, but also with the way of life. Age characteristics and the nature of the activity of a particular person, so the treatment of age-long-sightedness must be built taking into account the above nuances.
For those people who do not see only close, the best way to correct them is wearing glasses. This is the simplest and most accessible method. But with the simultaneous development of myopia, the patient will need to use bifocal glasses, which have two zones - one of them is designed to correct vision in the distance, and the other - to correct the vision at close range.
Among the effective methods of treating pathology are also mentioned exercises in the farsightedness, which can be performed whenever and wherever. In this gymnastics should be carried out only before meals and preferably several times a day. It is important to ensure that when performing exercise movements the eyes remain smooth.
In modern medicine for patients with age-long-sightedness, a variety of methods for contact correction of the visual organs work.
Recently, the use of multifocal contact lenses, which have a central and peripheral zone and is responsible for the clarity of vision, is very popular. This kind of lens helps to expand the field of view without deforming the visible objects. Thanks to the innovative material for making lenses, they allow the eyes to breathe, so with such lenses a person will not need to use glasses either near or far.
Correction of farsightedness according to the "monozyrenia" method assumes that one eye is adjusted for functioning near, and the second - for functioning in the distance, so a person will not need to wear glasses. But this kind of correction takes time for habituation and has a significant disadvantage, namely - the absence of binocular vision.
Treatment of senile farsightedness through surgery is carried out by replacing the lens of the eye, which has already lost its elasticity. Such an operation is organized in one day and takes only 15 - 20 minutes. The operation is performed under local anesthesia, changing the worn lens to the intraocular lens. All the operations of the surgeon ophthalmologist are performed through a pre-made self-sealing microsection of a length of 1.6 mm. After the completion of such an operation, it will not be necessary to impose seams. At present, with the goal of correcting the eyesight with the development of age-long-sightedness, accommodating or multifocal lenses are used.
Prevention of the development of the pathology of
It is impossible to completely prevent the development of age-long-sightedness, as the lens of the eye still loses its original properties with age. To increase the life of the lens and delay the development of hyperopia, as well as to slow the process of progressive deterioration in the work of the eye, it is necessary to prevent excessive eye strain, to choose the right lighting for a particular activity, to conduct eye gymnastics and take vitamin and microelements.
It is equally important to visit an ophthalmologist every year for a prophylactic examination, which, if revealed, can make a timely correction of vision, develop a suitable treatment for the eyes and emerging vascular pathology.
