| What is it used for? - Eye strain eg. computer operators, drivers
- Improving vision
- Protection against eye disorders
Why is it needed?
Good nutrition is important in maintaining the health of the eyes. A shortage of vitamin A may lead to poor vision, as this vitamin is essential in the formation of the retinal pigments responsible for vision. It has a protective effect (by virtue of its antioxidant activity) on the eye surfaces and retinal tissues, which are susceptible to damage by free radicals, produced through normal metabolic processes and sunlight. Bilberry contains the antioxidant vitamins A and C, known to reduce the risk of cataracts. One study has reported that the progression of cataract formation was halted in 97% of patients treated with a mixture of Bilberry and vitamin E. The flavonoids present in the herb have been shown to improve the function of the retina, improving night vision. In addition, this group of compounds has also been shown to possess hypoglycaemic action. How does it work? - Stimulates production of retinal pigments
- Collagen stabilising action
- Reduces capillary permeability
- Antioxidant
- Reduces blood glucose levels
The main constituents of Bilberries are known as anthocyanosides - a group of flavonoids. These have the ability to bind to the part of the retina which is responsible for vision, which in turn increases the rate of regeneration of the visual pigments in the retina.
In addition, the substances present in Bilberry have the ability to prevent the destruction of collagen, which is responsible for stabilising the delicate tissue structure of the eyes.
One particular anthocyanidin, myrtillin, has been shown to reduce blood sugar levels. |
