Healthy Eyes need the proper nutrients to function and to improve. If your eyes become tired or strained from work, driving or from constantly wearing contact lenses, Blueberry Extract offers excellent, natural relief. Its natural properties have been shown to have positive effects on the tired eyes.

Blueberry has been used over many years to improve night vision. Any beneficial effects associated with the blueberry may be due to anthocyanosides-flavonoid compounds that give the fruit its colour. Studies suggest that Blueberry extract accelerates rhodopsin regeneration. Rhodopsin is a chromoprotein used by rods in the eye for night vision.
Blueberry extract has been reported to modify several enzymatic parameters involved in retinal damage and may also improve microcirculation in the eye, promoting overall health and reducing eye strain.
A study in Japan concludes that Blueberry is beneficial for the prevention of
weak eyesight but that it does not have much of an effect on cataracts or
already weak eyes. According to the article, the best treatment for tired eyes
is to relax the eyes or take time to rest. For people always on the go who don't
have time to rest, Blueberry is the best way to relieve tired eyes. Anthocyanins are antioxidants which support the function of heart and vascular system.
