VITAMINS FOR THE EYE


The dip of light into the interior of the eye is a prerequisite for vision. The light is collected after it has been bundled in a certain spot of the retina, the macula. The macula is referred to as the "point of sharpest vision. Only with an intact macular good vision possible. Since the macula is the place inside the eye, the incident most of the light, it is exposed to an increased extent the high-energy blue components of light. This blue light can affect the viability of the macula over time. At the same time of old age often the concentration of the carotenoids lutein and zeaxanthin in the macula. This is because that most people take these protective substances with little food.

Both of these factors occurs in people in old age often results in age-related macular degeneration (AMD). The sight or the seeing sharp decreases and certain areas will be blurry, fuzzy or distorted view. Signs of such a change can be detected early with the Amsler grid.

For a healthy eye, the body needs special vitamins and trace elements:
Vitamin A is important for vision and a lack becomes apparent as night blindness or visual impairment.
Vitamin B2, vitamin C and vitamin E protect the eye from oxidative stress and against cell damage. High-energy radicals, e.g. the exposure to sunlight or about smoking come to mind are caught in antioxidants.
Selenium and zinc are also important antioxidants and zinc is directly involved in the visual process.
Special macular specific vitamins, carotenoids, lutein and zeaxanthin protect against harmful blue light and seem also rich in antioxidants.

Common causes of visual impairment:
* Age-related
* UV-light and blue light
* Bright Eyes (with light eyes more light reaches the interior of the eye)
* Female sex
* Smoking (in smoking resulting high-energy eye-damaging substances)
* Inequitable food.

What can you do?
* Vitamin C and E act as antioxidants and zinc on the eye and prevent cell damage. The specific macular carotenoids lutein and Zeaxanthein filter harmful blue light and act as antioxidants.
* A large-scale long-term study showed that the regular intake of vitamin C and E, carotenoids, zinc and the risk for the progression of age-related macular degeneration can be reduced. are preparations with the major carotenoids, lutein and Zeaxanthein in combination with key vitamins and trace elements are eyes in the pharmacy (dietary supplements containing vitamin A, B1, B2, B6, C, E, selenium, zinc, lutein, zeaxanthin).

When you need a doctor?
If you notice signs of macular degeneration, you should consult an eye doctor in any case.

Prevention:
* Healthy diet with adequate vitamins and trace elements, and in particular carotenoids (lutein and zeaxanthin are found in green leafy vegetables like spinach or kale).
* At the first sign of a slowing in the sense of a vision Macular degeneration is the right mix of vitamins, trace elements and minerals slow the progression of this disease.
* The eye with sunglasses strong light or UV radiation protection.
* No smoking.
