A disease in which patients have a clouding of the lens is called a cataract.. In 90% of cases, the disease is diagnosed in older patients and is a consequence of the natural aging process of the body.. Opacification of the lens cannot be prevented, it is irreversible and constantly progressive. The only effective treatment for cataracts is the removal of the clouded lens and the implantation of an intraocular lens, according to Pannochka, an online publication for girls and women aged 14 to 35.. net Why do cataracts occur?. When the lens begins to become cloudy, vision deteriorates, since not all light rays reach the retina and the visual image is formed indistinctly.. An eye with a cataract sees the image as if through a veil of fog..

The lens consists of a transparent protein compound, which, in violation of metabolic processes in the body and natural aging, begins to become cloudy. This process is irreversible, so it is important for all patients to understand that there are no drops that could restore transparency to the lens..

But there are drops that can significantly slow down the clouding process.. They are prescribed in the initial stages of cataracts, when it is not possible to perform an operation..

The process of maturation of a cataract can be compared to the denaturation of egg protein, which becomes white and dense during heat treatment.. There is no reverse denaturation process.

Cataracts can develop due to various reasons:.

aging and the natural aging process;

consequences of injury and exposure to toxic substances;

radiation exposure;

congenital pathology of the lens.

Increase the risk of developing cataracts diabetes mellitus, metabolic disorders, eye diseases, lack of vitamins and adverse environmental conditions.

Symptoms of the disease A characteristic visible symptom of a cataract is a change in the color of the pupil from grayish to milky white.. A mature cataract is easy to recognize on your own even without special equipment, but at this stage of maturation, the patient sees almost nothing. To conduct timely treatment and prevent vision loss, it is worth paying attention to the first symptoms of the disease and contacting the clinic in the early stages of cataract maturation..

Signs of cataract development are:.

sensitivity to bright light sources;

difficulty focusing vision while doing manual work or reading;

inability to choose optical means of vision correction;

color perception is weakened, the brightness of objects is lost;

visual acuity deteriorates in low light;

objects in front of the eyes are distorted and doubled.

The development of cataracts associated with age-related changes can begin at different times, as it depends on the individual characteristics of the body and the general state of human health.. Very often, the first symptoms occur in patients of working age, so you should not wait for the full maturation of the cataract and lose vision.. It is better to perform the operation when the cataract is immature in order to remain active, able to work and enjoy life freely after 50 years..
