Primary eye care (PEC) is a comprehensive term that encompasses the use of primary health care to avoid potentially blinding eye illnesses (PHC). PEC encompasses the identification of people with treatable causes of blindness, as well as the diagnosis and treatment of common eye conditions, notably those that cause an acute red eye. Primary eye care is a crucial component of blindness prevention in all communities and regions of the world. Only those who present to secondary and tertiary facilities will be diagnosed and treated without basic eye care, and little will be accomplished in terms of prevention. Acute care is required treatment for a short period of time due to a brief but serious illness, injury, or other eye health problem. At the secondary level, such as hospitals, ailments such as cataract, glaucoma, and trachoma are managed.
