What specific mechanism links black currant anthocyanins to improved vision health?

Answer

Anthocyanins help regenerate rhodopsin, a light-sensitive pigment in rod cells

The benefit of black currants for visual health, particularly concerning night vision and recovery from bright light exposure, is closely tied to their anthocyanin content. These pigments are believed to interact with the visual cycle by aiding in the regeneration of rhodopsin. Rhodopsin is the crucial photopigment found within the rod cells of the retina, which are responsible for vision in low-light environments. By supporting the restoration of this pigment, black currants assist the eyes in adapting more quickly to darkness or recovering visual clarity after being temporarily overwhelmed by intense light, thereby reducing visual fatigue.
