Formula Overview 4 Sight combines clinically-supported eye nutrients including zinc bisglycinate, taurine, N-acetyl-L-cysteine, bilberry fruit extract, alpha lipoic acid, quercetin, ginkgo biloba, lutein, zeaxanthin, and lycopene. Designed to support healthy eye function and provide antioxidant support to the retina. A note from Evey The eyes are how your body receives light. They are not just for vision; the cells at the back of the eye are the most direct sensors the body has for the time of day, the season, and the wavelength quality of the environment. Every aspect of how the body responds to light, from cortisol release in the morning to melatonin release at night, starts with what the eyes pick up. Protecting those cells is one of the highest-leverage acts in the longevity regimen. 4 Sight is built around the antioxidants that the retina actually uses. Lutein and zeaxanthin concentrate in the macula and act as built-in blue-light filters. Bilberry and zinc support retinal microcirculation. NAC, alpha lipoic acid, and quercetin contribute broader antioxidant support to a tissue that is especially exposed to oxidative stress because of its high oxygen demand and direct light exposure. The deeper why behind eye care is that the eyes are foundational, not optional. The supplement gives the retina the raw materials. The lifestyle gives them the right inputs: morning sunlight without sunglasses to set the daily clock, no screens close to bedtime, and time outdoors at midday. The supplement and the light environment work together, and neither one is sufficient alone. Take with food.
