The unique growing conditions in New Zealand include long hot summers and very cold winters, climatic factors that put the blackcurrant plant under mild stress. This leads to the high concentration of their rich nutrients.

These effects that were studied are considered to be mediated or lessened by increased blood flow in the peripheral circulation.

Blackcurrants are shown to greatly reduce visual fatigue following prolonged exposure to computer screens. And they begin to work just 2 hours after consumption.

The subject group that did not consume blackcurrants showed a significant deterioration in refractive index indicating visual fatigue, while those who consumed blackcurrants did not show these symptoms. The results were the following:

Dark adaptation is significantly improved with 50 mg anthocyanin.

Visual fatigue is significantly reduced with blackcurrant treatment.

Eye Health delivers 100 mg of anthocyanin per capsule, in addition vitamin A, lutein and zeaxanthin. There is significant research that shows lutein and zeaxanthin are beneficial for fighting cataracts, glaucoma and diabetic retinopathy and may slow the progression of age-related macular degeneration.
