Vision changes in the elderly the causes

After 40 years, there are gradual changes in the visibility of small objects, reading and writing at close range, a person begins to move the text further away from the eyes, while they quickly get tired, and the letters lose clarity, merge. As a natural factor of the body’s wear and tear, micro-changes affect many eye structures.

Clear visual interaction at close range is hampered by age-related changes in the lens associated with the densification of the nucleus, loss of elasticity, refractive ability.

Pupils narrow with the weakening of the muscles responsible for their size, as a result, the timeliness of the reaction to light is lost, the necessary degree of illumination when reading increases at times, the feeling of blinding when going out into the daytime sun.

Frequent age-related complaints are caused by watery eyes or excessive dryness, causing unpleasant sensations of pain, burning. There may be several reasons:

  • reduction of lacrimal gland production and accelerated evaporation of tears;
  • protective response to the harmful effects of adverse external factors;
  • reduction of control of lacrimation as a result of weakening of the motor skills of the eyelids;
  • increased lacrimation due to blocking of tear ducts;
  • the symptom of “wet eyes” is caused by some serious diseases – cataracts and others.

Peripheral vision narrows by several degrees every 10 years, which makes up a significant part of the visual field by the age of 70-80, increasing the risk of injuries and emergencies.

Significant inconveniences, especially for elderly people of artistic professions, are caused by a decrease in the main parameters of color sensation – brightness and contrast, due to the age-related reduction of retinal cells responsible for color perception.

At first glance, harmless sensations in the form of flies, floating opacities, shrouds or microflares can portend serious pathologies – detachment of the vitreous body or retina, the onset of cataracts and other diseases.

Degradation of the macula or the most light-sensitive part of the retina due to impaired blood supply to the nervous tissue is accompanied by loss of the ability to distinguish images, a noticeable weakening of vision.

The use of many medications, which elderly people often need, causes side effects associated with the state of visual function. Correct diagnosis and selection of drugs, accurate compliance with the conditions of admission allow you to cope with ailments and avoid possible deterioration of the visual system, exacerbation of existing eye diseases.

The natural aging of the eyelid skin leads to their flabbiness, the displacement of eyelashes in any direction, which provokes a stable state of corneal irritation, drooping eyelid or ptosis, which can turn from a cosmetic problem into a functional one, preventing the normal vision of objects and images.

DISEASES AND THEIR CONSEQUENCES FOR VISION

All known visual pathologies are considered by specialists as very serious. In the absence of adequate timely treatment, any violation of visual function can lead to loss of visual acuity and, in extreme cases, to senile visual disability.

A large list of symptoms of visual impairment, one way or another, is associated with diseases characteristic of the elderly. The most common of them are:

PRESBYOPIA OR AGE-RELATED HYPEROPIA

Pathology is associated with a violation of accommodation, which is noticed in most people by about 40 years, although some processes of a dystrophic nature involving the ciliary muscles, the internal environment of the eye occur even earlier. As a result, the compaction of the lens structures causes visual impairment during work, reading, and any action near.

There are effective measures for the treatment and correction of presbyopia, including surgical ones. Modern laser methods of thermokeratoplasty change the curvature of the cornea, modulating new shapes and vision capabilities. A more radical way is to replace the transparent lens, it optimally solves the problem in case of occurrence and joint elimination of cataracts.

It is possible to create comfortable conditions for visual work at a short distance by wearing glasses with positive glasses that compensate for the lack of accommodation. After the selection of glasses every 10 years, the strength indicators increase by about one diopter, the need for glasses depends on the degree of farsightedness. Contact lenses are also used, special spectral glasses have been developed for driving, long-term work at the computer,

CATARACT

Clouding of the lens causes the appearance of age-related cataracts, among the varieties of which nuclear, cortical and mixed forms are more common than others. Depending on the indications, medicinal and surgical treatment is used in different ways – extraction, lens implantation, lens replacement. Timely detection of pathology allows you to stop the process at an early stage and avoid surgery by focusing on medical treatment methods, at the initial stage, eye exercise complexes are effective.

GLAUCOMA

Regular measurement of eye pressure allows you to make a diagnosis in time – it is the increased tension inside the eyeball itself that is characteristic of this pathology. The initial stage of the disease is not accompanied by noticeable symptoms, so millions of people live with the problem, unaware of its existence. The inevitable consequence of glaucoma is a gradual loss of sensitivity of the vital optic nerve, followed by irretrievable loss of vision. The primary manifestations of the disease detected after 40 years can be treated by observing a strict regime of physical exertion, work, sleep and rest, and the correct selection of medicines. An integrated approach to therapy involves the appointment of antihypertensive and anti-glaucoma drugs, taking into account the degree of pathology. A popular surgical option is an iridectomy to equalize fluid pressure on different sides of the iris.

Notwithstanding the severity of such diseases, using drugs for curing them may not be as effective as preventing them. With Divine Vision 12 eye supplement you can stave off age-related eye changes and sight deterioration without exposing yourself to risk of severe adverse effects. In addition, the supplement can even reverse some damage made to your eyes.

FEATURES OF LASER CORRECTION FOR ELDERLY PATIENTS

There is a unanimous opinion of ophthalmologists that laser correction methods are most effective from the moment of adulthood to half a century. In older patients, pathological changes in the lens and the muscles holding it are accompanied by a violation of the coordinated work of the occipital lobe of the brain, responsible for the quality of vision. From here, the eye muscles receive signals, but the correction of the lens configuration becomes difficult, which worsens the focus of vision and the transfer to the retina of a picture located at a close distance. Such problems often accompany the aging of the body, and it is practically impossible to stop this process.

Laser correction procedures do not affect the manifestations of presbyopia, over the years farsightedness covers an increasing percentage of older people. The stabilization of vision at a certain age by compensating for farsightedness with myopia preceding throughout life is considered a delusion, since unresolved vision problems persist, forcing a person to have two pairs of working glasses — for nearness and distance. In this case, as a result, laser correction becomes one less problem. The right choice of technique can only be made by a professional ophthalmologist based on the results of a comprehensive vision diagnosis.

EYE DROPS AS A MEANS OF SOLVING VISION PROBLEMS

Modern ophthalmic drops have different purposes – vitamin and therapeutic, they can relieve fatigue, redness, dryness or swelling. An important nuance is that only a doctor can choose the ideal drug taking into account the personal characteristics of an elderly person.

IT IS IMPORTANT TO DRIP YOUR EYES PROPERLY

Instillation of the eyes only at first glance seems to be a simple procedure – to achieve the desired therapeutic effect, there are certain techniques that you need to know:

  • throwing back your head, you should pull back the lower eyelid and shake off the drop into the gap formed;
  • cover the eye by pressing the corner of the nose with your finger for a couple of minutes to prevent the drug from leaking out, as well as getting it into the sinus cavity;
  • before instillation, it is necessary to wash your hands thoroughly;
  • to study all the nuances of the instructions, the duration between instillations of different drugs;
  • in case of tremor of the hands, elderly patients need outside help or special devices to facilitate an independent procedure;
  • when wearing contact lenses, the doctor gives recommendations on the specifics of their use.

CONSEQUENCES OF AN INCORRECT PROCEDURE

Knowledge and compliance with the rules of using eye drops contributes to the complete retention of fluid until the therapeutic effect is achieved, preventing some unpleasant, undesirable side effects. Absorbed into the blood from the paranasal sinuses, ophthalmic drugs begin to circulate in the body, causing a number of complications in the form of:

  • asthma;
  • changes in the usual blood pressure level;
  • heart rate changes;
  • psychological deviations, depression.

A careful massage of the eyeballs helps to activate blood circulation and microcirculation of fluids, stabilizes the flow of impulses in the nervous system. A daily 10-minute procedure relieves eye fatigue, a feeling of pain and dryness. During the session, the tone of the eye muscles and general tension decreases. A full-fledged proper massage slows down the processes associated with loss of visual acuity.

Visual hygiene should be observed throughout life. At the age of 45 and older, it is recommended to check visual acuity annually in the office, even in the absence of complaints and alarming symptoms. Starting from the age of 55, the examination should be supplemented by measuring intraocular pressure simultaneously with fundus examinations.

Blinking is considered the most accessible and effective method of relieving fatigue – frequent intensive exercise perfectly relaxes the eyes, preserves and improves vision.

Mandatory breaks during work, during which you need to look intently into the distance, look at near and distant objects, close your eyes with your hands and quickly open them. It is necessary to limit physical, nervous, psychological stress, interrupting long classes for a few minutes every hour. Excessive tension contributes to the progression of eye diseases, negatively affects visual functions.

Tea compresses are best done with tea bags – this is an inexpensive and reliable method of relieving fatigue, restoring the tone of the eyelids and muscles.

Correct reading technique helps to preserve vision, while the plane of the text should be perpendicular to the direction of view. Optimal illumination gives reflected light, direct rays can irritate the nervous system, provoking unpleasant sensations.
