What is Bilberry?

Bilberry (Vaccinium myrtillus) is the European cousin to the blueberry and contains active ingredients that support vision. It was frequently used by World War II RAF pilots to enhance night vision.

Studies with bilberry show that it helps eyes adapt to the dark, especially after prolonged exposure to bright light and improves visual acuity in dim light. The active ingredients in bilberry, anthocyanosides, are a group of flavonoids that increase the production and integrity of collagen, a protein that forms connective tissue in the body. Bilberry is also used to treat artery, vein and capillary disorders. Bilberry extract has become the leading herbal prescription for the maintenance of healthy vision and for the treatment of many eye diseases.

Bilberry became valued as a medicinal agent during World War II when British pilots claimed that eating bilberries improved their visual acuity, night vision and ability to adapt to glare. Scientific studies have backed up these testimonials by uncovering bilberry’s antioxidant properties. Free radicals are unstable molecules that in their bid to become more stable must bump into healthy cells and cause damage.
Bilberry’s antioxidant properties neutralize free radicals and therefore reduce damage to vessels all over the body, including those in the eye. Cataracts are caused by free radical damage in the lens of the eye and therefore bilberry can treat cataracts. Other eye problems that are also helped by bilberry are: macular degeneration, diabetic retinopathy, night blindness and myopia.

Bilberry has anti-aging properties because as an antioxidant it protects the body against environmental pollutants other substances that and lead to aging. Bilberry also stabilizes the connective tissue called collagen. Thus it is beneficial for conditions of collagen instability in the vascular system such as varicose veins, phlebitis and heart disease. Finally, bilberry inhibits blood clotting and can be useful to increase circulation in cases of atherosclerosis and diabetes.

The berries of the bilberry plant contain the greatest concentration of the medicinally active ingredients, anthocyanadins. Supplements often contain the whole plant in encapsulated form. By purchasing supplements standardized to anthocyanadins one can be sure that there are some dried berries in the formula. Bilberry can be found in formulas for enhancing eye health and are often combined with other antioxidants, berries and herbs, such as eyebright.

Bilberry should be used with caution if you are nursing or pregnant. Bilberry can interfere with iron absorption and should not be taken at the same time as iron supplements. Bilberry may alter blood sugar levels and should be used cautiously in diabetics and hypoglycemics.

Eye Health

The eye is a very important sensory organ, which is shown by the fact that a large area of our brain is committed to taking in and understanding visual information. Up to 70% of all of the sensory receptors in the body are in the eyes. Problems with the eyes become more common as we age.

How can we support eye health, throughout our lifetime, so that our vision remains clear and focused?
The eye is a small sphere with a diameter of about 1 inch. Only one sixth of the eye is visible, the rest is protected in the orbital socket. There are many accessory structures of the eye including the eyebrows, eyelids, conjunctiva, lacrimal apparatus and eye muscles. Only a small part of the eye is dedicated to photoreception. This area is on the posterior wall on the inside the eyeball and is called the retina. It contains rods, for dim light and peripheral vision, and cones, for bright light and colour vision. The lens is situated at the front of the eyeball and its job is to focus light on the retina. Glasses are used to help focus light through the lens when the accommodation of the lens is inadequate or overcompensating. As we age, the muscles that move the lens decrease functioning making the use of glasses or contacts more common among older individuals.
