OCULAR Benefits of Vitamins and Micronutrients

Our Miami Beach eye specialist is an expert in ocular nutraceutical therapy. Recent scientific research suggests that using specific nutrient supplements may reduce your risk of certain ocular conditions. Specifically antioxidants have additional benefits for the eye.  Vitamin A protects against blindness and vitamin C may decrease cataract formation and oxidative ocular tissue damage

Omega-3 fatty acids found in fish oil and other food sources have shown great promise in promoting eye health  in a variety of ways, from reducing dry eye and macular degeneration.

A diet to promote health of your eyes should include brightly colored fruits and green leafy vegetables.

The following  nutrients have been shown to be essential for healthy vision and may protect your eyes from certain conditions and diseases.
