Vitamins for vision are necessary not only to improve the quality of vision, 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. Blueberry extract contains a large amount of anthocyanin.
The antioxidant works as follows:
- protects tissues from free radicals;
- strengthens capillaries and vessel walls;
- prevents thrombosis;
- improves blood flow and metabolic processes;
- stimulates enzymatic activity.
The second group is made up of products containing carotenoids – organic pigments that also act in antioxidant protection. The most famous are beta-carotene, lutein and lycopene. They are able to slow down the age-related degeneration of retinal tissue, reduce the risk of developing cataracts and have a preventive effect on a number of other diseases.
The third group are complexes with microelements and minerals: zinc, selenium, calcium. Zinc is considered especially useful as it supports the function 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 depending 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. Dissolving 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 serious illnesses. Dietary supplements are necessary for those who spend more than 5 hours a day in front of a computer screen, for those who wear contact lenses and for people over 40 years old, since during this period age-related changes associated with the deterioration of quality of vision. period.
Mineral complexes are prescribed at the first signs of hyperopia or myopia, as well as symptoms of increased intraocular pressure.
Eye vitamins for hyperopia or myopia do not restore visual acuity, but 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.
The main thing is to choose the right vitamins in accordance with your age and health status.
Vitamin A
Retinol is responsible for visual acuity, color perception and regeneration. Strengthens corneal tissue and normalizes the functioning of visual organs. Retinol deficiency 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 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 lens from opacities and help the optic nerve function.
All vitamins in this group support the body's visual functions.
Vitamin C
Ascorbic acid is a vitamin for vision, necessary to strengthen blood vessels and reduce the risk of bleeding. Regular redness of the whites of the eyes indicates frequent damage to capillaries and a deficiency 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 occurring in the human body.
Vitamin E
Tocopherol is responsible for antioxidant protection. Maintains the permeability of vascular tissues, thanks to which nutrients reach cells more quickly. This element is present in most medicines that combat age-related changes.
Nuances 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);
- flavor (presence of flavoring and aromatic additives);
- contraindications and side effects;
- age;
- the presence of concomitant pathologies and diseases;
- better before the date.
When purchasing vitamins to improve visual acuity and prevent eye diseases, one should not count on instant action. The effect most often occurs after completing 2-3 courses, the duration and frequency of which are 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, leafy greens, apricots and tomatoes. Thiamine can be found in legumes, bread bran, 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 peppers, as well as rose hips, black currants and raspberries.
Tocopherol deficiency can be leveled by introducing carrots, sea buckthorn, lettuce, greens, butter and eggs into the diet.
Conclusion
For the purpose of preventing or treating eye diseases, various vitamin complexes, eye drops and medications are prescribed. Remember that medications are prescribed individually, only by the 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 optometrist or ophthalmologist. At these visits, you can discuss your concerns and address your individual eye care needs.
