Macular degeneration associated to aging is a degenerative eye disease that affects an area of the eye retina called "macula". The macula is directly responsible for central vision, necessary for everyday activities like reading, driving or identifying individuals.
Symptoms
- Blurred vision and decreased visual acuity.
- Distorted perception of distances and heights.
- Straight lines may appear wavy.
- Dark spot in the center of the field of vision.
Risk factors
- The main risk factor is age, since the disease can affect middle-aged people and risk increases with age.
- Race: White people are more likely to develop macular degeneration, especially its severe forms.
- Family history: People with relatives who have presented macular degeneration are at increased risk of developing the disease.
- Gender: It seems that women are more at risk than men.
- Smoking: tobacco has been linked to an increased risk of suffering it.
- Obesity: It can lead to the progress of macular degeneration. From an initial / intermediate form of the illness to a more severe one.
Other risk factors: high fat diet; estrogen levels; high blood pressure; cardiovascular diseases; solar radiation; iris color, etc.
Active ingredients
-Lutein / Zeaaxanthin: Carotenoids xanthophylls (yellow pigments) which act as a biological filter, absorb blue light, improve visual resolution and protect from photo-oxidation. They accumulate mainly in the central area of the eye retina (macula) and pigment it. Their main function is protecting the macula and lens:
- 1. Filtering UV light.
- 2. Reducing the effects of oxidative damage.
Protection against lipid peroxidation. Prevents cataract formation. There is scientific evidence against macular degeneration.
-Zinc: Trace element which is part of ocular tissues and allows the vision process. It acts as an antioxidant in the retina and pigmented epithelium. It regulates the light-rhodopsin reaction. Modulates synaptic transmission in the retina.
-Vitamin A: Fundamental in the process of day and night vision. Indispensable for rhodopsin regeneration, whose decomposition by light allows the process of vision.
-Vitamin C: is found in high concentration in the aqueous humor of the eye. Thanks to its antioxidant power, it protects the lens of processes that could lead to opacification. Lowers intraocular pressure in glaucoma.
-Vitamin E: Found in high concentrations in the retina and essential to its operation. Prevents oxidation of cell membranes. Protective effect of vitamins A and C. Prevention of cataracts.
