What is the primary prevention method for Conjunctivitis?

Frequent hand washing is the primary prevention method for conjunctivitis, as this practice significantly reduces the risk of spreading infections. Conjunctivitis, or pink eye, can be caused by bacteria, viruses, or allergens, and it is often highly contagious. Proper hand hygiene helps to eliminate pathogens from the hands, which can easily be transferred to the eyes or to surfaces that others may touch. By washing hands regularly—especially after touching the eyes or face, or before preparing food—individuals can effectively minimize the likelihood of contracting or spreading conjunctivitis.

In contrast, while avoiding bright lights and wearing sunglasses can provide comfort for individuals already experiencing symptoms of conjunctivitis, they do not address the prevention of the infection itself. Similarly, isolating an infected child may help prevent the spread within specific settings, but it does not constitute a broad preventive measure applicable to the general population. The most effective strategy to prevent the occurrence of conjunctivitis remains good hygiene practices, particularly hand washing.
