What term is used to describe an eye condition where images are focused at two points instead of one?

Hyperopia
Myopia
Astigmatism
Emmetropia

The correct answer is: Astigmatism

The term that describes an eye condition where images are focused at two points instead of one is astigmatism. This condition occurs when the cornea or lens has an irregular shape, causing light rays to be refracted unevenly. As a result, instead of focusing at a single point on the retina, images are blurred and can be focused at multiple points, leading to distorted vision. In contrast, hyperopia refers to farsightedness where distant objects can be seen more clearly than close ones as their focal point is behind the retina. Myopia is nearsightedness, meaning close objects are clear, while distant objects are blurred because their focal point is in front of the retina. Emmetropia indicates normal vision where light focuses correctly on the retina, and there are no refractive errors present.
