Nearly 80 percent of all impressions reach our brain via the eyes. Today, we know that this much is true – the eye is not there merely to see! It is an important “outpost” of our health. The eye perceives and receives frequencies of colored light, converts these frequencies into electromagnetic impulses, sorts them and then sends them to the brain, influencing both our physical and emotional wellbeing.The high-quality colored lenses of the optiCOLORvision Glasses can have effects that are beneficial to the health, in the case of emotional and physical illnesses and stress.
