What Onion Juice Can Actually Do

Onion juice cannot reverse refractive errors like nearsightedness or farsightedness.

It won’t cure glaucoma, cataracts, or serious retinal conditions.

Any claims of “better vision in 5 days” are exaggerated.

A Safe Way to Try It

If you want to incorporate onion juice for gentle eye support:

Option 1: Dietary

Add raw onions to salads, smoothies, or meals. This provides quercetin and sulfur compounds safely.

Option 2: Juice Method (Internal Use Only)

Juice a small amount of onion (1–2 tablespoons).

Mix with carrot or apple juice to improve taste.

Drink 2–3 times per week for antioxidant support.

⚠️ Caution:

Avoid putting onion juice directly into your eyes—it can cause severe irritation.

People with digestive sensitivity should start with small amounts.

✅ Bottom Line: Onion juice can gently support eye comfort and reduce minor inflammation, but it won’t magically improve vision. Eating onions regularly as part of a balanced diet is the safest, most effective approach.
