Vitamins for vision are needed not only to improve the quality of the latter, but also to prevent eye diseases. Drugs 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 is a preparation in which the main active ingredient is anthocyanin. This is a biologically active substance that has a significant antioxidant effect. Blueberry extract contains large amounts of anthocyanins.
Antioxidants act as follows:
- protect tissues from free radicals;
- strengthens capillaries and vessel walls;
- prevent thrombosis;
- improve blood flow and metabolic processes;
- stimulate 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 delay age-related degeneration of retinal tissue, reduce the risk of cataracts and have a preventive effect in several other diseases.
The third group is complex with microelements and minerals: zinc, selenium, calcium. Zinc is considered very useful, as it supports the function of the optic nerve. Preparations with a high zinc content are used for glaucoma and some other age-related pathologies.
Drops or capsules: which is more effective?
The form of medicine is chosen based on the type of disease. In case of corneal or lens pathology, it is recommended to use drops that are quickly distributed over the iris. For retinal diseases, take tablets or capsules. Dissolved in the blood, they release active substances that reach the inner part of the eye (retina). With drops this effect is not possible.
Who needs eye vitamins?
It is recommended to take vitamins not only for pathologies or severe diseases. Supplemental nutrition is needed 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 age-related changes associated with deterioration in the quality of vision begin at 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 myopia 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 adverse 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 function of the visual organ. Retinol deficiency leads to the development of conjunctivitis and dry eye effects.
Group B
For normal vision function, 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 at dusk;
- pyridoxine (B6) supports the function of the optic nerve and participates in the transmission of impulses, reduces muscle tension, and prevents nervous tics;
- cobalamin (B12) stimulates blood circulation, protects the lens body from opacification, and helps the function of the optic nerve.
All vitamins in this group support the visual function of the body.
Vitamin C
Ascorbic acid is a vitamin for eye sight, needed to strengthen blood vessels and reduce the risk of bleeding. Frequent redness of the white part of the eye 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 against ultraviolet rays and the oxidation process that occurs in the human body.
Vitamin E
Tocopherol is responsible for antioxidant protection. It maintains the permeability of vascular tissue, thanks to which nutrients reach the cells faster. This element is found 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 ingredients);
- form of release (drops or tablets);
- flavor (the presence of flavorings and aromatic additives);
- contraindications and side effects;
- age;
- the presence of pathology and concomitant 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 occurs after completing 2-3 courses, the duration and frequency of which is determined by the doctor.
Natural source of vitamins
You can get 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 beans, bran bread, fish and seafood. Riboflavin is found in green vegetables, lettuce, 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 in rose hips, black currants, and raspberries.
Tocopherol deficiency can be leveled by including carrots, sea buckthorn, lettuce, vegetables, butter and eggs in the diet.
Conclusion
For the purpose of prevention or treatment of eye disorders, various vitamin complexes, drops and medicines are prescribed. Remember that medicines are prescribed individually, only by a doctor. By choosing it 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 this visit, you can discuss your concerns and address your individual eye care needs.
