Patients with conjunctivitis should avoid spicy foods, such as onions, leeks, garlic, chili peppers, lamb, dog meat, and other heat-inducing comfort foods, which are not conducive to the early recovery of the disease. Additionally, they should consume less shrimp, crab, and other seafood that may exacerbate the condition. Smoking is also prohibited due to the presence of nicotine in cigarettes, which constricts blood vessels and can worsen red eye, thus smoking must be strictly avoided. Furthermore, alcohol consumption should be avoided as it can prolong the disease.
