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 in which the main active ingredient is anthocyanin. This is a biologically active substance that has a pronounced antioxidant effect. Blueberry extract contains a large amount of anthocyanins.
The antioxidant works as follows:
- protects tissues from free radicals;
- strengthens capillaries and blood 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 the retinal tissue, reduce the risk of developing cataracts and have a preventive effect on a number of other diseases.
The third group is complexes with microelements 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 pathologies associated with aging.
Drops or capsules: which is more effective?
The form of the drug is chosen based on the type of disease. In case of pathology of the cornea or lens, it is recommended to use drops that are quickly distributed over the iris. For diseases of the retina, take tablets or capsules. Dissolving in the blood, they release active substances that reach the inner part of the eye (retina). This effect is not possible with drops.
Who needs eye vitamins?
It is recommended to take vitamins not only for severe pathologies or diseases. Dietary supplements are mandatory 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, because in that period the age-related changes associated with the deterioration of vision begin. period.
Mineral complexes are prescribed for 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 be beneficial for vision?
Even healthy people need bioactive substances. They protect the organs of vision from harmful 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 work of the visual organs. Lack of retinol leads to the development of conjunctivitis and dry eye effect.
Group B
For the normal functioning of vision, 4 types of vitamins from this group are necessary:
- 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 the sharpness of vision at dusk;
- 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 clouding and help the functioning of the optic nerve.
All vitamins from this group support the visual functions of the body.
vitamin C
Ascorbic acid is a vitamin for vision, necessary for strengthening blood vessels and reducing the risk of bleeding. Regular redness of the whites of the eyes indicates frequent capillary damage and a lack of this bioactive element.
Vitamin C also stimulates collagen production and prevents the development of cataracts. It is necessary for protection against ultraviolet radiation and oxidation processes that take place in the human body.
vitamin E
Tocopherol is responsible for antioxidant protection. It maintains the permeability of vascular tissues, thanks to which nutrients reach the cells faster. This element is present in most drugs that fight against age changes.
Shades of choice
When choosing eye vitamins to improve vision, pay attention to:
- composition (name and content of active substances);
- release form (drops or tablets);
- taste (presence of aromatic and aromatic additives);
- contraindications and side effects;
- Age;
- the presence of accompanying pathologies and diseases;
- best by date.
When buying vitamins to improve visual acuity and prevent eye diseases, you should not count 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 medicines, but also naturally - from food.
Sources of retinol are blueberries, grapefruit, celery, 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 in beef, milk and dairy products. The source of ascorbic acid is citrus fruits. There is even more of it in peppers, as well as in barberries, black currants and raspberries.
Tocopherol deficiency can be compensated by introducing carrots, sea buckthorn, lettuce, greens, butter and eggs into the diet.
Conclusion
For the purpose of prevention or treatment of eye disorders, various vitamin complexes, drops and medicines are prescribed. Please note that medications are prescribed individually, only by a doctor. If you choose 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 an ophthalmologist or ophthalmologist. During these visits, you can discuss your concerns and address your individual eye care needs.
