Vitamins for vision are necessary 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.
First, there are preparations in which the main active ingredient is anthocyanin. It is a biologically active substance with a clear antioxidant effect. Blueberry extract contains a large amount of anthocyanin.
Antioxidant works as follows:
- protects tissues from free radicals;
- strengthens capillaries and vascular 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 trace elements and minerals: zinc, selenium, calcium. Zinc is considered particularly beneficial because it supports the function of the optic nerves. Preparations with a high amount of zinc are used for glaucoma and a number of other age-related pathologies.
Drops or capsules: which is more effective?
The form of the drug is selected according to 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. Take tablets or capsules for retinal diseases. 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 required for those who spend more than 5 hours a day in front of a computer screen, wear contact lenses and people over 40 years old, because age-related changes in the quality of vision begin at this period. 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 help vision?
Even healthy people need bioactive substances. They protect the organs of vision from negative external influences, nourish the 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 function of the organs of vision. Deficiency of retinol leads to the development of conjunctivitis and dry eye.
Group B
4 types of vitamins from this group are needed for normal vision function:
- 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 at dusk;
- pyridoxine (B6) supports the work 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 opacity and help the work of the optic nerve.
All vitamins in this group support the body's visual functions.
Vitamin C
Ascorbic acid is a vitamin for eye sight that is needed to strengthen blood vessels and reduce the risk of bleeding. 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 to protect against ultraviolet radiation and oxidation processes occurring in the human body.
Vitamin E
Tocopherol is responsible for antioxidant protection. It protects 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.
Nuances of choice
When choosing eye vitamins to improve vision, you should pay attention to the following:
- composition (name and composition of active substances);
- release form (drops or tablets);
- taste (presence of flavoring and aromatic additives);
- contraindications and side effects;
- age;
- the presence of accompanying pathologies and diseases;
- best before date.
When taking vitamins to improve visual acuity and prevent eye diseases, you should not rely on instant action. The effect occurs most often after completing 2-3 courses, the duration and frequency are determined by the doctor.
Natural sources of vitamins
You can buy vitamins not only from pharmaceuticals, but also naturally - from food.
Sources of retinol are blueberries, grapefruit, celery, greens, apricots and tomatoes. Thiamine can be found in legumes, wholemeal bread, fish and seafood. Riboflavin is found in green vegetables, salads, seeds and nuts.
Vitamin B6 can be found in liver and eggs, while B12 can be found in beef, milk and dairy products. The source of ascorbic acid is citrus fruits. It is most abundant in bell peppers, as well as in rose hips, black currants and raspberries.
Tocopherol deficiency can be eliminated by including carrots, tea leaves, lettuce, greens, butter and eggs in the diet.
The result
Various vitamin complexes, drops and medicines are prescribed for the prevention or treatment of eye diseases. Remember that drugs 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.
