What is the term for an eye condition where images are correctly focused on the retina?

1. Astigmatism

2. Hyperopia

3. Myopia

4. Emmetropia

The correct answer is: Emmetropia

The term describing an eye condition where images are accurately focused on the retina is emmetropia. This state refers to the normal vision where light rays converge precisely on the retina when the eye is at rest, enabling clear vision at multiple distances. Conditions like astigmatism, hyperopia, and myopia represent refractive errors, where images do not focus correctly on the retina, leading to blurred vision. In astigmatism, the cornea or lens is irregularly shaped, causing distorted vision. Hyperopia, or farsightedness, means that distant objects are seen more clearly than close ones due to light focusing behind the retina. Myopia, or nearsightedness, occurs when nearby objects are seen clearly, while distant ones appear blurred, as light is focused in front of the retina. Therefore, emmetropia stands out as the condition indicating correct focusing on the retina.
