Anthocyanins are plant pigments that strengthen eyesight and improve color and contrast perception. They are also known as strong antioxidants and free radical scavengers and have a positive effect on microcirculation. After taking Luminox®, the blueberry active ingredient anthocyanins is absorbed by the body and passed on to the visual organs. It has its positive effect in the retina. This strengthens the visual cells and prevents premature eye fatigue. Night and twilight vision as well as contrast vision is improved and sensitivity to glare is reduced. Luminox® contains purely plant-based and nature-identical active ingredients and is therefore extremely well tolerated.
