Presbyopia Treatment Surgery Symptoms Signs Causes

The presbyopia also known as illness of short hands, is the term describing an eye in which the natural crystalline lens does not accommodate. Accommodation is an ability of an eye to change the focal length. In its basis ability of a crystalline lens to change the optical force by change of the geometry - thickness in the central part, curvature of forward and back surfaces, position in an eye lays. Approximately at 40-year-old age the crystalline lens becomes less flexible, loses the ability to change the form and position, and accommodation is gradually lost. It is normal process which tests everyone.

The majority of people with normal sight in a youth is closer by 40 years starts to pay attention to difficulties at reading of the texts, printed small a font. The font seems low-contrast, blurring. Eyes quickly get tired. First text removal on more distance from eyes helps the majority of people. But as a result it appears, that without points or contact lenses not to manage any more. This process can proceed up to 65 - 70 years that will be shown in necessity to wear more and more strong plus glasses or lenses. At some people, with the latent far-sightedness, sight afar after 40 years too worsens. Laser or surgical correction Here can already be necessary. However, people with short-sightedness of weak and average degree do not notice influence presbyopia as well see close.

Signs symptoms

It is difficult to make out details at work close

The small text looks low-contrast

For reading brighter and direct illumination is required

To read the text, it is necessary to take away it on the big distance

Weariness and pressure of eyes at reading

The presbyopia is found out at sight and refraction check.

Treatment

Treatment presbyopia is simple, but the hobby completely depends on age of the patient, style of a life, a trade. If sight afar good, also there are problems only with sight close, most easier to choose glasses. In other situation (with correction bifocals will be necessary for a distance) or two pairs points - one for a distance. Other variant is a so-called sight: one eye is adjusted on sight afar, another - on sight close. It can be spent contact lenses or surgery.

The presbyopia (age far-sightedness) is a pathology of a refraction of an eye connected with the years. Approximately by 40 years of a life the person has sclerous changes in a crystalline lens that leads to consolidation of its kernel so, ability of an eye to accommodation is broken. Therefore to the person points for reading are required. This process progresses with the years, that plus of dioptries for reading leads to increase, and approximately by 60-70 years the crystalline lens absolutely loses ability to change the radius of curvature and people should dress points about plus lenses and separate points for "distance" (for example, for reading of a dioptry and for a distance - for people not suffering neither short-sightedness, nor a far-sightedness). It is inevitable age process which to stop it is impossible. Age changes differently pass for people with different pathologies of a refraction.

The presbyopia with a congenital far-sightedness is shown more often in sight decrease, both for reading, and for a distance, practically simultaneously. Thus, presbyopia aggravates a congenital (axial) far-sightedness.

Presbyopia at people with short-sightedness, especially with small, are in the most favourable if it is possible so to say, position. This minus compensates loss of accommodation and removes the moment of putting on of points. Patients with short-sightedness, most likely, will not require at all similar points. People with such degree of short-sightedness wear glasses for a distance and remove points for work close.



The presbyopia, or as her often name, senile sight traps the person, as a rule, on the middle of its course of life, is elderly about forty years. There is inconvenient a reading, especially in the evening. Sight afar usually remains normal. As a rule, presbyopia at comes earlier, rather than miopia. Many people perceive sight worsening with the years as natural result of ageing. "I am already old, they and consequently sight quite often brings me speak." It is considered, that with the years crystalline lens fabrics are condensed also it ostensibly does not allow a muscle to change curvature of a crystalline lens to focus an eye on nearby object. Followers have visually proved, that widespread opinion on inevitable deterioration of sight with the years, wrongly. It was neatly expressed in P.Bregg's this occasion: " The age does not weaken eyes. The age is a measure, instead of force. The age is the best pretext which they can find to justify the wrong vital habits which were the reason of deterioration of sight. ".

Presbyopia considered as one of forms. In the theory he, as is known, did not consider a crystalline lens as the accommodation factor, therefore its hardening should not affect with the years accommodation in any way. The reason of deterioration of sight at presbyopia sees in the mental pressure caused by effort to make out nearby objects. Some other opinion adheres one of followers. He considers, that the unique reason of approach presbyopia is a wrong food. "Up to today, he writes, it was supposed, that with achievement by the person of middle age of an eye naturally change the form (being slightly compressed), doing thus inconvenient vision of NEARBY objects and causing presbyopia.

It is considered as causing inconvenience, but a necessary payment which we should bring for so long existence in this world! This problem dares a glasses wearing with convex lenses. Very much few of millions suffering senile sight (or their medical advisers) realise, that for this change in visual possibilities their WRONG HABITS of a FOOD within 45-50 years of their life answer; but it, undoubtedly, illness, and sight of many suffering from presbyopia can be restored simple introduction of a reasonable diet and performance of several simple exercises on eyes. To underline vital communication between food and sight, it is enough to inform, that there are data on set of authentic cases of the bad sight cured by simple STARVATION. The clarification which has improved at starvation leads the collected stocks of products of ability to live which hammered in muscles and the blood vessels surrounding eyes. As result, muscles relax, and sight improves ".

To the book "System Bregg for sight improvement" pays attention to importance of receipt of enough of vitamins in an organism of people of an average and advanced age. She writes: "Senile sight is in most cases directly connected with a vitamin C lack, and there where there is a lack of one vitamin, deficiency of other important vitamins" is always observed. Last phrase of the author should be understood so: by special researches it has been established, that efficiency duty of vitamins can increase or decrease depending on presence of certain substances, for example, other vitamins. So, it has been defined, that efficiency of some vitamins of group In and vitamin C at their combinative reception. In more details you can familiarise with questions of the correct organisation of a diet in section.
System Bejtsa recommends at presbyopia:

1. Daily to read a small font at good and at dim illumination. Reading can be spent as without points (if it is possible), and to them. The Same measure is considered an effective prophylactic against presbyopia if it to spend daily, since 35 years.

2. To use correctly organised diet. It is recommended to reduce a share of sweet and fat dishes in a diet and to increase a share bitter by taste and fresh vegetables.

3. As considers presbyopia as one of forms (far-sightedness), you should follow all volume that is written in the previous section for the exercise, intended for them.
