For a simple fresh salad, combine thinly sliced red onion with cucumber, tomato, parsley, olive oil, and lemon juice. This provides a flavorful combination of vegetables without claiming that the food itself can treat an eye disease.
If you notice cloudy vision, sudden changes in eyesight, flashes of light, new floaters, eye pain, or loss of vision, don’t rely on a home remedy—seek an eye examination promptly. Cataracts, for example, can cause cloudiness and blurred vision, but when they significantly affect sight, the established treatment is an ophthalmological assessment and, when appropriate, cataract surgery.
So, enjoy raw red onion for its flavor and nutritional value—but don’t use it as a substitute for glasses, prescribed treatment, or an eye examination.
