Hyperopia is commonly known as farsightedness. This condition occurs when the eyeball is shorter than normal or when the cornea has too little curvature, causing light rays entering the eye to be focused behind the retina instead of directly on it. As a result, individuals with hyperopia typically have difficulty seeing nearby objects clearly, while distant objects may still appear relatively clear.

In contrast, nearsightedness refers to myopia, where close objects are seen clearly, while faraway objects appear blurry. Color blindness involves difficulties in distinguishing colors, and astigmatism is a condition where the eye's surface is irregularly shaped, causing blurred or distorted vision for both near and distant objects. Understanding the distinctions among these conditions is important for recognizing and addressing vision-related issues in a school setting.
