XXI in Tepic, Nayarit

This article distills research-backed steps to protect vision and reduce risks of conditions like age-related macular degeneration, cataracts, and dry eye. It highlights nutrient-dense foods—leafy greens rich in lutein/zeaxanthin, colorful fruits and vegetables for vitamins A and C, nuts and seeds for vitamin E, legumes and lean meats for zinc, and fatty fish for omega‑3s—plus the importance of hydration. It outlines proven habits: don’t smoke, wear UV‑blocking sunglasses, manage blood sugar and blood pressure, follow the 20‑20‑20 rule for screens, get enough sleep, practice contact lens hygiene, and schedule regular dilated eye exams. The piece also clarifies when supplements help (e.g., AREDS2 for certain people with intermediate AMD) and what has limited evidence (routine blue‑light–blocking glasses), helping patients and caregivers make confident, practical choices with their clinicians.
