Which of the following conditions is characterized by light focusing behind the retina?

Hyperopia, commonly known as farsightedness, is characterized by light focusing behind the retina. This occurs because the eye is either too short in its axial length or the cornea has too little curvature, preventing light rays from focusing directly on the retina. As a result, distant objects may be seen more clearly than close ones, leading individuals with hyperopia to experience difficulty with near vision tasks.

Understanding the relationship between how light focuses and various vision conditions is crucial in diagnosing and managing eyesight-related issues. Hyperopia can often be corrected with prescription glasses or contact lenses that help converge light rays so they can focus correctly on the retina, allowing for clearer vision at all distances. This condition is distinct from myopia, where light focuses in front of the retina, astigmatism, which involves an irregular curvature of the cornea resulting in distorted vision, and presbyopia, which relates to the loss of flexibility in the lens as one ages, affecting the ability to focus on near objects.
