1. Protection Against Oxidative Stress
Antioxidant Defense: The core function is to combat the oxidative stress caused by factors like aging, blue light from screens, and environmental pollution.
The "7 vital bio-available fruit, flower and bark extracts" (which typically include ingredients like Bilberry, Lutein, and Zeaxanthin in vision formulas) are rich in powerful antioxidants (like anthocyanins and carotenoids).
Action: These antioxidants neutralize harmful free radicals that can damage delicate eye tissues, particularly the cells of the retina and the lens.
2. Enhanced Retinal and Macular Support
Ingredients like Lutein and Zeaxanthin (common in vision supplements and often sourced from flowers) act as a natural filter to absorb harmful blue light.
Action: By accumulating in the macula—the central part of the retina responsible for sharp, detailed vision—they help maintain the density of the macular pigment, which is crucial for sharp focus and reducing glare sensitivity.
3. Circulation and Vascular Health
Certain extracts (like Bilberry or other bark extracts) are known to contain compounds that support microcirculation.
Action: By promoting healthy blood flow to the tiny capillaries in the eye, they ensure that the retina and other ocular structures receive the necessary oxygen and nutrients, supporting overall function.
4. Essential Nutrient Replenishment
The "essential vitamin and mineral support" typically includes nutrients like Vitamin C, Vitamin E, and Zinc.
Action: These vitamins and minerals support the overall structure, immune function, and health of the eye, from the clear lens to the protective outer tissues, helping the eye's natural repair and defense processes.
