Eyes are not only a reflection of a person’s soul, but also an indicator of their state of health. As a result of which the cornea can be affected and how to avoid it? Let's go through the steps.
What does the human eye consist of ?
The human eye has a shape similar to a ball, which is why it is called the eyeball. The body consists of three shells:
- outer part;
- vascular;
- retina.
The cornea itself is located on the front of the outer sheath, and it is similar to a transparent glass. Through it, sunlight enters the vascular and reticular 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. If there is a lack of vitamin, this will be discussed in the course of the article.
The nerve cells of the eyeball are located mainly in the reticular ball, which provides a person with a visual perception of the world. On the retina there is a display of objects on which the gaze is fixed, and the subsequent analysis of information - in the brain.
What should be consumed and in what doses in order to maintain the health of the eye and, in particular, the cornea? The simple answer is vitamins and minerals, and which ones, we will analyze in more detail.
Why consume vitamins?
Every human body needs constant replenishment with vital components, such as vitamins, hormones, and trace elements.
The cornea of the eye is affected when there is a shortage of any substance, which provokes rapid wear, aging and progressive loss of vision. For the prevention of diseases associated with the eyes, it is necessary to 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 absorbed better, it is necessary to dilute the carrots with sugar or sour cream and eat a small portion at least once a day.
- Also, the cornea of the eye is affected with a lack of vitamin C. In large quantities, it is found in citrus and marine products. Eating daily food that contains a lot of vitamin C, you can not only preserve eye health, but also prevent many other diseases.
- Vitamin retinol, tocopherol, pyridoxine are necessary components for the prevention of eye diseases.
In addition to the deficit of the above substances, other factors can become the cause of the pathology.
Causes of eye damage
The cornea of the eye is most susceptible to all kinds of injuries. This is due to the fact that she is closest to the external environment and the first to take the blow.
In addition to 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 injury 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 constant local irritant.
- Temperature exposure is directly related to ocular pathologies. A burn or frostbite can cause deep damage.
- Chemical effects in the form of drugs or toxins.
Corneal erosion. Clinic. Etiology
The cornea of the eye is affected by a lack of protective forces of the body, as well as due to local pathological effects on the epithelial cells of the eyeball.
If we talk about erosion, 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 globe of the eyeball.
To identify this pathology, it is necessary to compare your feelings with the following clinical signs:
- fear of light and constant causeless lacrimation;
- visual defects of the horn ball;
- blurred eyes and others.
If you suspect an erosive process, you should immediately contact an oncologist to prevent possible complications.
Vitamin retinol. Act
The cornea of the eye is affected with a lack of retinol, because this vitamin element should be a mandatory component of each person’s daily diet.
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 cancer pathologies. It neutralizes all the most aggressive types of free radicals.
An adult should consume about 1000 micrograms of vitamin retinol per day, but it is important to note that the maximum allowable dose is no more than 3000 micrograms 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 products such as meat, salmon, liver, as well as various oils.
In another way, tocopherol is called vitamin E. It is the strongest antioxidant that accumulates in large doses in adipose tissue. Why is the cornea affected by a lack of vitamin E? This is due to the fact that tocopherol normalizes the work of many organs and promotes the rapid healing of some injuries.
The useful action is as follows:
- It facilitates 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 the immune forces, which occurs due to the regenerative abilities of vitamin E. Also, tocopherol is used as a remedy for blood clots - it strengthens the walls of capillaries.
- Slows down skin aging.
- It is 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. What products can I get this item from? For example, pine nuts, horseradish, pomegranate, mackerel fish, sardines, sea buckthorn and others contain a large amount of this substance.
A dangerous period for the eyeball may be a lack of this vitamin, which is especially acute in cases such as:
- intense sports;
- prolonged exposure to cold air;
- a large number of proteins that come with food;
- stressful situations.
Therefore, in order to be sure of the health of the eye, and especially the cornea, it is necessary to use a greater amount of the vitamin component of pyridoxine during the periods indicated above.
What are eye diseases?
What other common pathological changes can be observed?
The fact that the cornea is affected by a lack of vitamins, we have already made out. It remains to determine what other diseases may occur.
- Allergic reactions associated with increased body sensitivity and corneal susceptibility to irritation.
- Mesh 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 a malfunction of the nerve cells of the eyeball.
How to avoid the presented pathologies? There are special preventive measures for this.
Eye Disease Prevention
As a preventative measure, it is recommended to undergo regular medical examinations and consult a specialist if any pathological changes are found.
A balanced diet with the use of all the elements discussed in this article will help to avoid the severe consequences of deficiency.
To preserve the youthfulness of the eyes and an attractive look, it is necessary to do gymnastic exercises while working at the computer, as well as use protective sunglasses.
As centuries-old practice shows, any disease is easier to prevent than to cure. Therefore, the care of eye health lies directly on the shoulders of each person, and the goal of specialists in this matter remains to be vigilant and direct their efforts to preventive rather than medical procedures.
