You may have heard claims that onion can improve your vision in just 5 days. While that might sound too good to be true, onion does contain nutrients that support overall eye health — but let’s set realistic expectations.

🧅 Why Onion Can Support Eye Health

Onions are rich in:

Quercetin – a powerful antioxidant that helps reduce inflammation and oxidative stress in the eyes.
Sulfur compounds – important for producing glutathione, a key antioxidant that protects the lens of the eye.
Vitamin C – supports eye tissue repair and immune function.

While these won’t “cure” vision problems overnight, they can support long-term eye health naturally when combined with a healthy lifestyle.

🍵 Simple Home Remedy Using Onion

Ingredients:

½ fresh onion (red or white)
1 teaspoon of honey (optional, for 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.
Optional: add a bit of honey if drinking.
Drink once daily in the morning, on an empty stomach, for 5 days.

⚠️ Important: This is for internal use only.
Do not apply onion juice to your eyes — it can cause irritation or even damage.

👁️ Bonus Natural Tips for Better Eyesight

Eat more greens – spinach, kale, and broccoli are full of lutein and zeaxanthin.
Stay hydrated – dryness can worsen eye strain.
Do eye exercises – try the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.
Get enough sleep – your eyes repair while you rest.

💡 The Bottom Line

Onion won’t magically fix your eyesight in 5 days — but it’s a healthy, antioxidant-rich food that can help protect and support your vision naturally over time. Combine it with other healthy habits, and your eyes will thank you!
