The increasingly high number of patients with dry eye, allergy and other manifestations of acute and chronic irritant to the outer surface of the eye, has made the ocular surface diseases are now one of the most frequent reasons for consultation daily ophthalmological practice.
It is estimated that in general, dry eye occupies 40% of ophthalmologic consultations and allergic symptoms by 22%, while rates influenced by the action of natural and manmade environmental changes and pollution.
This high incidence, has placed the ocular surface as a major pole of attraction for current ophthalmic research.
In response to this pathology, Bausch & Lomb, a leader in eye health care, introduced Ocuvite Omega 3, a new formula with Omega 3 and Lutein, essential for preventing and treating ocular surface diseases. Read the rest of this entry »
As with all our body systems, eye imbalances are related to certain factors:
- The need for an adequate blood supply: The eyes need hydration and nutrition from the blood.
- The presence of pigments.
- Antioxidant nutrients.
- The state of the blood vessels.
In recent years, has discovered the importance of two carotenoids, lutein and zeaxanthin-against oxidative and degenerative processes of the retina and the macula, where they are in great concentration. Supplementation with 10 mg of lutein and 400 micrograms of zeaxanthin increases the presence of these pigments in the macula, visual health improvement and reduces the risk of AMD. On the other hand, is evidence of the connection between the degeneration of tissues in the eye and the state of the blood vessels leading to the area. Thus, hardening or loss of flexibility of the arteries is a risk factor, since the capillaries of the eye can rupture and create microhemorrhages generated vision loss.
Not forgetting the essential vitamins A, C, E and zinc, you should also add to the intake of lutein and zeaxanthin, 50 mg of standardized extracts of bilberry fruit, 50 mg and 10 mg of zarzarmora grape seed. The anthocyanidins in these fruits exert a powerful effect against free radicals that attack the eye structures have phlebotonics action, improve microcirculation, promote the regeneration of retinal and macular pigment and improved visual acuity.
Proper nutrition not only benefits the overall health, but also extends to eye health, especially as we age. You can also consume certain vitamins and nutrients, according to numerous investigations, nourish and protect the integrity of the eyes. Here is a summary of those findings.
The fruits may reduce the risk of progressive macular degeneration (AMD, for its acronym in English). A study by the Channing Laboratory of Harvard Medical School, indicates that people who consume a daily diet with several servings of fruits may reduce the risk of developing AMD in old age. The study compared the intake of antioxidant vitamins and carotenoids (as beta carotene) as well as fruits and vegetables among the elderly participants and found that those who ate three or more servings of fruit per day over a period of 12 to 18 years , reduced the risk of suffering from progressive macular degeneration by more than 30 percent, compared with those who consume 1.5 servings daily or less often.
Dry eye syndrome may also be related to excessive intake of fats in the diet. It is a painful and debilitating disease that particularly affects women and is characterized by a reduction in the quality and quantity of watery eyes. Symptoms include the emergence of a firestorm that, left untreated, can lead to scarring or ulceration of the cornea and vision loss. Researchers at Brigham and Women’s Hospital and Schepens Eye Research Institute (Boston, Massacusetts) reached that conclusion after studying the eating habits of 37,000 women.
According to the coordinator of the study, Biljana Miljanovic, “observed that a high intake of omega-3 fatty acids, common in oily fish and nuts, is related to a protective effect for the eyes, in contrast, a higher proportion of omega 6 present in oil dressing or sauces, may increase the risk of dry eye syndrome. The researcher stressed that only the discrimination of omega 3 versus omega 6 in the diet reduces the risk of dry eye by almost 70%.
