What Onion Juice Can Actually Do

Onion juice contains beneficial compounds, but it’s not a miracle eyesight cure. Its main benefits for eye health come from:

Quercetin – Anti-inflammatory support

Reduces oxidative stress and inflammation around the eyes.

May ease tired or dry eyes, or mild irritation.

Sulfur Compounds – Antioxidant boost

Helps your body produce glutathione, protecting eyes from environmental stress.

Vitamin C – Gentle tissue support

Contributes to repair and immunity, which indirectly supports eye comfort.
