The eyesLike all the organs in our body, they undergo the phenomenon of aging. Fortunately, there are natural substances that can prevent and treat degenerative eye diseases such as cataracts and macular degeneration.
Cataract, a disease of the lens
The crystalline is a small lens needed to focus images at the retina. It is an organ that is very sensitive to all the metabolic disorders associated with aging. Its loss of elasticity will result in difficulty focusing during near vision (presbyopia) while its progressive opacification (cataract) will result in decreased vision that can lead to blindness.
Macular degeneration, a disease of the retina
Macular retinal degeneration is the second leading cause of blindness in older adults after cataracts. The retina is a neuro-sensory membrane made up of numerous nerve cells rich in lipids that are very sensitive to oxidation generated by free radicals from ultraviolet radiation. These nerve cells predominate in the central part of the retina (macula) where two yellow pigments,lutein and zeaxanthin, which are natural pigments with a "local" antioxidant effect, are concentrated.
If the macula deteriorates, the center of the visual field becomes blurred. Only the peripheral vision remains normal.
A concentrate of vitamins for the eyes
Lutein is a naturally occurring pigment, found in green vegetables, some fruits, corn and egg yolk. It plays a primary protective role against macular degeneration and cataracts by neutralizing the harmful effects of ultraviolet light emitted by the sun and blue light emitted by artificial lighting.
Zeaxanthin is also a natural pigment found in all plants to allow them to resist the temperature and harmful effects of the sun.
Lutein and zeaxanthin are important factors in the adaptation of vision to darkness as well as in the vision of shapes and colors.
Astaxanthin (a natural extract from the algae Haematococcus pluvialis) is the red pigment that colors shellfish and some fish and has particularly potent antioxidant activity. Numerous studies demonstrate the protective role of astaxanthin in the eyes against damage induced by exposure to ultraviolet rays.
Blueberry extract, rich in bio-flavonoids, improves night vision, increases the strength of the eye's capillaries, and promotes oxygenation and nutrition of ocular tissues.
Red vine(Vitis vinifera) protects against eye glare, one of the symptoms of the dry form of age-related macular degeneration.
The Ginkgo Biloba is a plant that significantly improves distance vision in people with macular degeneration.
Taurine is the most concentrated amino acid in the eye because it is essential for proper functioning of the retina and optic nerve.
L-Carnosine is a natural antioxidant that protects the eye from light-induced damage.
