Definición y Significado de "vision screening"

What is a "vision screening"?

A vision screening is a quick test used to check how well a person can see. It helps identify potential vision problems, such as nearsightedness or farsightedness, before symptoms are noticeable. Vision screenings are commonly done in schools, clinics, or doctor's offices and typically involve simple tasks like reading letters or looking at shapes. If a problem is detected, further tests by an eye specialist may be needed.
