Blackmores Bilberry Eyestrain Relief helps to relieve eyestrain and eye fatigue caused by daily computer use, night driving and fine detail work, and help support night vision. Bilberry may also help reduce the risk of damage to the microcirculation of the eye.
The key constituents of bilberry are the anthocyanosides. These constituents give bilberry antioxidant properties. In addition the anthocyanosides have been shown to increase the strength and reduce the permeability of the capillaries and in this way bilberry helps to reduce damage to the microcirculation of the eye.
The anthocyanosides in bilberry help to maintain visual acuity (sharpness) and improve night vision through their action on rhodopsin. Rhodopsin is a light sensitive pigment found in the rods of the retina. Rhodopsin is essential for eyesight in dim light and needs to be quickly regenerated in order for the eye to maintain visual sensitivity.
