Bad for vision: we keep sharpness

Section 1: Vision as a valuable gift: understanding of the foundations

Vision is one of the most important feelings that allows us to perceive the world in all its glory. It directly affects our daily life, performance, social activity and general quality of life. A modern way of life, characterized by long -term work at the computer, the effects of blue light from screens, poor ecology and malnutrition, has a significant negative effect on the health of the eyes. In order to effectively maintain vision, it is necessary to understand its fundamental mechanisms and factors affecting its deterioration.

1.1 Anatomy of the eye: Brief review

To understand the action of dietary supplements for vision, it is necessary to have a basic idea of the anatomy of the eye. Key structures involved in the process of vision include:

Cornea: A transparent outer shell focusing light.
Iris: The painted part of the eye regulating the amount of light falling into the eye.
Pupil: The hole in the rainbow shell through which the light passes.
Crystalik: Linza focusing light on the retina.
Retina: A photosensitive fabric lining the back of the eye. It contains photoreceptors (sticks and cones), converting light into nerve impulses.
Vine nerve: Passes nerve impulses from the retina to the brain, where they are interpreted as an image.
Makula: The central region of the retina, responsible for acute vision and color perception.

1.2 Mechanism of view: as we see

The process of vision is a complex chain of events:

Light falls into the eye: Light, reflected from objects, passes through the cornea and pupil.
Focusing the world: The cornea and the crystal focus on the retina.
The transformation of light into nerve impulses: Photoreceptors (sticks and cones) in the retina convert light into nerve impulses. The sticks are responsible for vision in low light conditions, and cones for color vision and visual acuity.
Transfer of nerve impulses to the brain: The visual nerve transfers the nerve impulses from the retina to the visual cortex of the brain.
Image interpretation: The brain processes nerve impulses and creates a visual image.

1.3 Factors affecting vision:

Vision is influenced by many factors, both external and internal. Knowing these factors helps to make reasonable decisions to protect vision.

Age: With age, vision naturally worsens. Diseases such as presbyopia (age -related farsightedness), cataracts and age -related macular degeneration (VMD) are developing.
Heredity: A genetic predisposition plays an important role in the development of many eye diseases.
Environment: The effect of ultraviolet radiation, contaminated air and blue light from the screens can damage the eyes.
Life: Improper nutrition, smoking, excessive alcohol consumption and lack of physical activity negatively affect the health of the eyes.
Health status: Some diseases, such as diabetes, hypertension and autoimmune diseases, can lead to vision problems.
Work at the computer: Long -term work at the computer can lead to a dry eye syndrome, eye fatigue and visual impairment.

1.4 common problems with vision:

There are many vision problems that can affect the quality of life. Some of the most common include:

Myopia (myopia): Fuzzy vision in the distance.
Hyperopy (farsightedness): Fuzzy vision near.
Astigmatism: Uneven focusing of light leading to distorted vision.
Presbiopia (age farsightedness): A decrease in the ability to focus on close objects, usually develops after 40 years.
Cataract: The clouding of the lens, leading to a deterioration in vision.
Glaucoma: Damage to the optic nerve, often associated with high intraocular pressure.
Age macular degeneration (VMD): Damage to the macula, leading to a deterioration in central vision.
Dry eye syndrome: The lack of lubrication of the eyes, leading to discomfort and irritation.

Section 2: The role of dietary supplements in maintaining the health of the eyes

Biologically active additives (dietary supplements) for vision are designed to provide the body with nutrients necessary to maintain the health of the eyes and prevent diseases. They are not medicines and are not intended for the treatment of diseases, but can be a valuable addition to a healthy lifestyle and diet.

2.1 The principle of operation of dietary supplements for vision:

Dietary supplements, as a rule, contain a combination of vitamins, minerals, antioxidants and other nutrients that have a positive effect on the health of the eyes. They can work in several ways:

Protection against oxidative stress: Antioxidants, such as vitamin C, vitamin E, zinc and selenium, help protect the eye cells from damage by free radicals.
Improving blood circulation: Some dietary supplements, such as ginkgo biloba extract, can improve blood circulation in the eyes, providing more oxygen and nutrients.
Eye structure support: Some nutrients, such as collagen, can support the structure and elasticity of eye tissue.
Improving the work of photoreceptors: Some dietary supplements, such as lutein and zeaxantin, can improve the function of photoreceptors in the retina.
Reduced inflammation: Some dietary supplements, such as omega-3 fatty acids, have anti-inflammatory properties that can help protect the eyes from damage.

2.2 Key ingredients of dietary supplements for vision and their properties:

Various dietary supplements contain various ingredients, each of which has its own unique properties. Here are some of the most common and effective ingredients:

Lutein and Zeaxanthin: These are carotenoids that accumulate in the retina and macula, protecting them from damage in blue light and oxidative stress. They are especially important for the prevention of VMD. Studies have shown that the intake of Luthein and Zeaksanthin can improve visual acuity and reduce the risk of the development of VMD.
Vitamin C: A powerful antioxidant protecting the eyes from damage by free radicals. It also plays an important role in the synthesis of collagen necessary for the health of eye tissue.
Vitamin E: Another powerful antioxidant that protects the eye cells from oxidative stress. It can also help improve blood circulation in the eyes.
Zinc: An important mineral that plays a role in many body functions, including vision. It helps vitamin A move from the liver to the retina, where it is used to produce the pigment necessary for vision. Zinc deficiency can lead to a deterioration in night vision.
Selenium: Antioxidant, which works synergistically with vitamin E to protect the eyes of the eyes from damage.
Omega-3 fatty acids: Important to the health of the retina and can help reduce the risk of developing dry eye syndrome. They also have anti -inflammatory properties. Particularly important are daily acidic acid (DGK) and eicopascentaic acid (EPK).
Vitamin A: It is necessary for the normal functioning of the retina and night vision. Vitamin A deficiency can lead to chicken blindness.
Blueberry extract: Contains anti -vocals, which are powerful antioxidants. They can help improve blood circulation in the eyes and protect them from damage. Blueberry extract is often used to improve night vision and reduce eye fatigue.
Extract of grape seeds: Contains proanthocyanidines, which are powerful antioxidants. They can help protect the eyes from damage to free radicals and improve blood circulation.
