Will lemon juice constrict your eyes?

Lemon juice can cause temporary eye irritation if it comes into contact with your eyes, potentially leading to a stinging sensation or tearing. However, it does not cause the pupils to constrict; rather, light exposure and certain medications can lead to pupil constriction. If lemon juice accidentally gets in your eyes, it's important to rinse them with water immediately and seek medical advice if irritation persists.
