Final answer:
Eye prophylaxis, such as eye exams and treatment for conditions like trachoma and cataracts, is mandatory in the United States to prevent blindness and promote eye health. In the case of trachoma, it is rare in the United States due to better sanitation and access to clean water.
Step-by-step explanation:
Eye prophylaxis, such as eye exams and treatment for conditions like trachoma and cataracts, is mandatory in the United States to prevent blindness and promote eye health.
In the case of trachoma, it is rare in the United States due to better sanitation and access to clean water. However, trachoma is prevalent in developing countries, mainly in Africa and Asia, where access to clean water is limited. Trachoma can lead to blindness if left untreated, so early detection and treatment are crucial.
Cataracts, another common cause of vision loss, can be prevented and treated through regular eye exams. By detecting cataracts early, individuals can receive appropriate treatment, such as surgery, to restore their vision.
