There is no reliable scientific evidence that applying guava leaves, guava fruit, or guava leaf tea directly to the eyes treats eye infections, cataracts, glaucoma, blurred vision, or other eye diseases. Putting homemade preparations into the eyes can introduce bacteria or irritants and may worsen the condition.
That said, guava can support overall eye health as part of a nutritious diet because it contains:
- Vitamin C, which helps protect cells from oxidative stress.
- Vitamin A (small amounts), which is important for vision.
- Antioxidants such as lycopene (especially in pink guava varieties).

Guava leaf tea (for drinking only)
Some people drink guava leaf tea for its antioxidant content.

- 2 cups water
Method

Do not use this tea as eye drops or an eye wash.
Avoid these practices
- Do not place guava leaf juice in the eyes.

These methods are not proven to be effective and may increase the risk of eye infection or irritation.
When to seek medical care
If you have any of the following, it’s important to be examined by an eye care professional promptly:
- Eye pain
- Sudden vision loss or blurred vision
- Redness with discharge
- Injury to the eye
- Light sensitivity
- Flashes of light or a curtain over your vision
If you tell me which eye problem you’re trying to treat (for example, dry eyes, redness, itching, cataracts, glaucoma, diabetic eye disease, or blurry vision), I can explain which treatments are supported by evidence and whether any natural approaches may help alongside standard care
