Vitamins for vision are needed not only to improve the quality of the latter, but also to prevent eye diseases. Medicines are selected based on the diagnosis, age and individual characteristics of the patient.
Types of drugs
Vitamin complexes can be divided into 3 categories.
The first are preparations where the main active ingredient is anthocyanin. This is a biologically active substance that has a pronounced antioxidant effect. Cranberry extract contains a large amount of anthocyanins.
The antioxidant acts as follows:
- protects tissues from free radicals;
- strengthens capillaries and vessel walls;
- prevents thrombosis;
- improves blood flow and metabolic processes;
- stimulates enzyme activity.
The second group consists of products containing carotenoids - organic pigments that are also involved in antioxidant protection. The most famous are beta-carotene, lutein and lycopene. They are able to slow down the age-related degeneration of retinal tissues, reduce the risk of developing cataracts and have a preventive effect on a number of other diseases.
The third group is complexes with trace elements and minerals: zinc, selenium, calcium. Zinc is considered particularly beneficial, as it supports the functioning of the optic nerves. Preparations with a high zinc content are used for glaucoma and a number of other age-related pathologies.
Drops or capsules: which is more effective?
The form of the medicine is chosen based on the type of disease. In case of pathology of the cornea or lens, it is recommended to use drops that dissolve quickly over the iris. For diseases of the retina, take tablets or capsules. Being dissolved in the blood, they release active substances that reach the inner part of the eye (retina). With dots this effect is not possible.
Who needs eye vitamins?
It is recommended to take vitamins not only for pathologies or serious diseases. Dietary supplements are necessary for those who spend more than 5 hours a day in front of a computer screen, those who wear contact lenses and people over 40 years old, as age-related changes related to the deterioration of the quality of vision begin during this time. period.
Mineral complexes are prescribed at the first signs of farsightedness or myopia, as well as for symptoms of increased intraocular pressure.
Eye vitamins for farsightedness or myopia will not restore visual acuity, but will normalize metabolic processes.
What vitamins will benefit vision?
Even healthy people need bioactive substances. They protect the organs of vision from negative external influences, nourish tissues and prevent the development of pathologies.
Vitamin A
Retinol is responsible for visual acuity, color perception and regeneration. It strengthens the tissue of the cornea and normalizes the functioning of the visual organs. Retinol deficiency leads to the development of conjunctivitis and the dry eye effect.
Group B
For the normal functioning of vision, 4 types of vitamins from this group are needed:
- thiamine (B1) stabilizes intraocular pressure, participates in the transmission of information to the brain, maintains visual acuity;
- riboflavin (B2) normalizes blood flow and metabolic processes, nourishes tissues, protects against the negative effects of ultraviolet radiation and is responsible for visual acuity during twilight;
- pyridoxine (B6) supports the functioning of the optic nerve and participates in the transmission of impulses, reduces muscle tension and prevents nervous tics;
- cobalamins (B12) stimulate blood circulation, protect the body of the lens from opacities and help the functioning of the optic nerve.
All vitamins of this group support the body's visual functions.
Vitamin C
Ascorbic acid is a vitamin for vision, necessary for strengthening blood vessels and reducing the risk of hemorrhages. Regular redness of the whites of the eyes indicates frequent damage to the capillaries and a lack of this bioactive element.
Vitamin C also stimulates collagen production and prevents the development of cataracts. It is necessary for protection from ultraviolet radiation and oxidation processes occurring in the human body.
Vitamin E
Tocopherol is responsible for antioxidant protection. It preserves the permeability of vascular tissues, thanks to which nutrients reach the cells faster. This element is present in most drugs that fight age-related changes.
Shades of choice
When choosing eye vitamins to improve vision, you should pay attention to:
- composition (name and content of active substances);
- release form (drops or tablets);
- taste (the presence of aroma and aromatic additives);
- contraindications and side effects;
- age;
- the presence of accompanying pathologies and diseases;
- best before date.
When buying vitamins to improve visual acuity and prevent eye diseases, you should not rely on immediate action. The effect most often appears after the end of 2-3 courses, the duration and frequency of which is determined by the doctor.
Natural sources of vitamins
You can get vitamins not only from pharmaceuticals, but also naturally - from food.
Sources of retinol are blueberries, grapefruit, celery, collard greens, apricots and tomatoes. Thiamine can be found in legumes, bran bread, fish and seafood. Riboflavin is found in green vegetables, salads, seeds and nuts.
Vitamin B6 can be found in liver and eggs, and B12 can be found in beef, milk and dairy products. The source of ascorbic acid is citrus fruits. Even more is found in bell peppers, as well as rose hips, black currants and raspberries.
Tocopherol deficiency can be reduced by introducing carrots, thorns, lettuce, greens, butter and eggs into the diet.
CONCLUSION
For the purpose of preventing or treating eye disorders, various vitamin complexes, drops and medications are prescribed. Remember that medications are prescribed individually, only by a doctor. By choosing them yourself, you risk making the problem worse.
Perhaps one of the most important and easiest ways to keep your eyes healthy is to have an annual eye exam with your eye doctor or ophthalmologist. At these visits, you can discuss your concerns and address your individual eye care needs.
