Patient One Meso-Z Vision supplies a complex of lutein, zeaxanthin and meso-zeaxanthin, naturally occurring plant pigments (carotenoids) that are concentrated in the macula. Research has shown that macular pigment increases when these three carotenoids are taken together. Meso-Z Vision also helps protect the eyes from blue light. Today's "digital lifestyle" increases high-energy blue light exposure, a new concern for all age groups. Blue light exposure is often associated with electronics with LED screens including computer monitors, smart phones, tablets, e-readers, and TV. This formula helps absorb blue light and naturally filters blue light.
