You might have come across claims that onions can improve your vision in just 5 days. While that sounds a bit far-fetched, onions do contain nutrients that promote overall eye health — but it’s important to have realistic expectations.

🧅 How Onion Can Support Eye Health

Onions are packed with:

Quercetin – a strong antioxidant that helps reduce inflammation and oxidative stress in the eyes.

Sulfur compounds – essential for producing glutathione, a vital antioxidant that protects the eye’s lens.
Vitamin C – aids in eye tissue repair and boosts immune function.
While these won’t “cure” vision issues overnight, they can help maintain long-term eye health when combined with a balanced lifestyle.

🍵 Simple Home Remedy Using Onion

Ingredients:

½ fresh onion (red or white)

1 teaspoon of honey (optional, for a smoother taste)

½ cup of warm water

Method:

Grate or blend the onion and strain the juice.

Mix 1–2 teaspoons of onion juice with warm water.

Optionally, add honey for taste.

Drink once daily in the morning on an empty stomach for 5 days.

⚠️ Important: This remedy is for internal use only.

Do not apply onion juice directly to your eyes, as it can cause irritation or damage.
