Eyes are not only a reflection of a person's soul, but also an indicator of his state of he alth. As a result of which the cornea can be affected and how to avoid it? Let's go through the steps.
What is the human eye made of?
The human eye is shaped like a ball, which is why it is called the eyeball. The organ consists of three shells:
- outer;
- vascular;
- retina.
The cornea itself is located on the front of the outer shell, and it is similar to a transparent glass. Through it, sunlight enters the vascular and mesh ball. Due to its convex shape, it not only perceives, but also refracts rays.
It often happens that the cornea of the eye is affected. With a lack of which vitamin this happens, we will analyze in the course of the article.
The nerve cells of the eyeball are located mainly in the mesh ball, which provides a person with a visual perception of the world. On the retina, objects are displayed on which the gaze is fixed, and the subsequentinformation analysis - in the brain.
What should be consumed and in what doses to maintain the he alth of the eye and, in particular, the cornea? The answer is simple - vitamins and trace elements, and which ones, we will analyze in more detail.
Why take vitamins?
Every human organ needs a constant replenishment of vital components such as vitamins, hormones and trace elements.
The cornea of the eye is affected by a lack of any substance, which provokes rapid wear, aging and progressive loss of vision. To prevent diseases associated with the eyes, you must include the following vitamin components in your diet:
- Often the cornea of the eye is affected by a lack of vitamin A, which is found in large quantities in carrots. In order for the vitamin element to be better absorbed, it is necessary to dilute carrots with sugar or sour cream and eat a small portion at least once a day.
- Also, the cornea of the eye is affected by a lack of vitamin C. It is found in large quantities in citrus and marine products. Eating a daily diet rich in vitamin C can not only keep your eyes he althy, but also prevent many other diseases.
- Vitamin retinol, tocopherol, pyridoxine - necessary components for the prevention of eye diseases.
In addition to the deficiency of the above substances, other factors can become the cause of the pathology.
Causes of eye damage
The cornea of the eye is moreprone to all sorts of injuries. This is due to the fact that it is closest to the external environment and the first to take a hit.
Besides the fact that the cornea of the eye is affected by a lack of trace elements and vitamins, other factors can also cause the disease:
- Traumatic damage to the orbit. This happens when a foreign body enters the eyeball and destroys its integrity. The cause may be an accidental foreign body or a persistent local irritant.
- Temperature exposure is directly related to eye pathologies. Burning or frostbite can cause deep injury.
- Chemical influence in the form of drugs or toxins.
Erosion of the cornea. Clinic. Etiology
The cornea of the eye is affected due to a lack of body defenses, as well as due to local pathological effects on the epithelial cells of the eyeball.
If we talk about erosions, then, most likely, the cause is a violation of the integrity of the membrane as a result of mechanical or chemical damage to the cornea. Also, the pathological process can begin to progress after degenerative or inflammatory changes in the ball of the eyeball.
To identify this pathology, you need to compare your feelings with the following clinical signs:
- fear of light and constant causeless lacrimation;
- visualhorn ball defects;
- cloudy eyes and others.
If you suspect an erosive process, you should immediately contact an oncologist to prevent possible complications.
Vitamin retinol. Action
The cornea of the eye is affected by a lack of retinol, so this vitamin element should be a mandatory component of the daily diet of every person.
It is found in carrots, fish products, fruits, liver, etc. The presented vitamin is fat-soluble, and an overdose of this component is impossible, because it is absolutely non-toxic to the human body.
In addition, retinol belongs to the list of antioxidants and is used as a preventive measure in relation to oncological pathologies. It neutralizes all the most aggressive types of free radicals.
An adult should consume approximately 1,000 mcg of retinol vitamin per day, but it is important to note that the maximum allowable dose is no more than 3,000 mcg of this element.
Tocopherol
The cornea of the eye is affected by a lack of tocopherol, which explains the need for daily use of this component along with foods such as meat, salmon, liver, and various oils.
In another way, tocopherol is called vitamin E. It is the strongest antioxidant that accumulates in adipose tissue in large doses. Why is the cornea of the eye affected by a lack of vitamin E? This is due to the fact that tocopherolnormalizes the work of many organs and promotes the rapid healing of some injuries.
The useful action is as follows:
- Eases the course of diabetes and improves the general condition of patients who suffer from diseases associated with fluctuations in blood sugar. This also applies to Alzheimer's disease.
- Strengthening of immune forces, which occurs due to the regenerative abilities of vitamin E. Tocopherol is also used as a remedy for blood clots - it strengthens the walls of capillaries.
- Slows down skin aging.
- Useful during menopause in women, as it compensates for the lack of a hormone such as estrogen.
- Used to treat herpetic lesions, ulcerative and other pathological processes on the skin.
An adult should consume up to 10 IU per day, a child - 7 IU.
Vitamin pyridoxine
The cornea of the eye is affected by a lack of pyridoxine, that is, vitamin B6. From what products can this element be obtained? For example, a large amount of this substance contains pine nuts, horseradish, pomegranate, mackerel fish, sardines, sea buckthorn and others.
A dangerous period for the eyeball can be a lack of this vitamin, which is especially acute in cases such as:
- intense sports;
- prolonged exposure to cold air;
- large amount of protein that comes from food;
- stressful situations.
Because, in order to be sure of the he alth of the eye, and especially the cornea, it should be during such periods,above, consume more of the vitamin component pyridoxine.
What are eye diseases?
What other common pathological changes can be observed?
The fact that the cornea of the eye is affected by a lack of vitamins, we have already figured out. It remains to determine what other diseases may arise.
- Allergic reactions associated with hypersensitivity of the body and susceptibility to irritation of the cornea.
- Met angiopathy can occur when the eye vessels are affected, and this process is accompanied by a disorder of the nervous system.
- Astigmatism is a serious pathology, which is manifested by a violation of refraction, that is, objects are distorted, lose their shape and blur.
- Atrophic changes in the optic nerve can occur as a result of neuralgia or disruption of the nerve cells of the eyeball.
How to avoid the presented pathologies? There are special preventive measures for this.
Prevention of eye diseases
As a preventive measure, it is recommended to undergo regular medical examinations and consult a specialist if any pathological changes are found.
A balanced diet with all the elements mentioned in this article will help to avoid the severe consequences of a deficiency.
To maintain youthful eyes and an attractive look, it is necessary to do gymnasticexercise while working at the computer, and use protective sunglasses.
As centuries-old practice shows, any disease is easier to prevent than to cure. Therefore, care for eye he alth lies directly on the shoulders of each person, and the goal of specialists in this matter remains to be vigilant and direct their efforts towards preventive rather than curative procedures.
