What to drink to improve eyesight?

Hydration can support general health, but juice or tea should not replace assessment of a vision problem.

The NEI dry-eye guide discusses drinking water as one lifestyle measure, alongside care chosen for the cause and severity of dry eye. That is not evidence that a drink corrects vision.

The National Eye Institute healthy-vision advice recommends a balanced diet with varied fruit and vegetables, including leafy greens. Seek an eye-care professional’s advice for changes in vision.
