Why Eye Supplements?
Eyes decline due to:
- Age-Related: Macular/retinal decay, increasing AMD/cataract risk․
- Digital Strain: Screen use causes dry eyes, blue light damage․
- Nutritional Gaps: Diet alone may lack optimal vision nutrients․

- Omega-3 Fatty Acids: DHA (in retina) crucial for function․ Anti-inflammatory Omega-3s aid dry eye, retinal health․
- Vitamin C & E: Potent antioxidants protecting eye cells․ Vitamin C in aqueous humor; Vitamin E prevents oxidative stress, reducing cataract progression, supporting tissue․
- Zinc: Highly concentrated in eyes․ Aids Vitamin A transport for melanin, vital for vision (especially night)․ Key in AMD prevention․
- Vitamin A (Beta-carotene): Crucial for low-light vision․ Precursor to Vitamin A, supports retinal photoreceptors․ Deficiency causes night blindness, dry eyes․
- AREDS/AREDS2 Formula: Studies-derived, combines high doses of C, E, Zinc, Copper, Lutein, Zeaxanthin․ Proven to significantly slow intermediate/advanced AMD․

- Quality & Dosage: Choose reputable brands; adhere to dosages․ Excessive intake is harmful․
- Diet First: Supplements complement, not replace, a healthy diet (greens, fruits, fatty fish, nuts)․
