The Snellen Chart is primarily utilized in examinations of which body part?

The Snellen Chart is specifically designed to assess visual acuity, making it an essential tool in eye examinations. It consists of a series of letters that decrease in size, allowing healthcare professionals to determine how well a patient can see at various distances. By having patients read the letters from a set distance, practitioners can evaluate their vision and identify any potential issues, such as nearsightedness or farsightedness. This focus on visual function distinguishes the Snellen Chart from tools used to assess other body parts, such as the heart, lungs, or kidneys, which utilize different methods and examinations for evaluation.
