Myopia is commonly known as what type of vision defect?

Myopia, often referred to as nearsightedness, is a vision defect where individuals can see nearby objects clearly while distant objects appear blurry. This condition occurs when the shape of the eye causes light rays to focus in front of the retina instead of directly on it.

Understanding myopia helps explain its practical implications in daily life. People with myopia often need to wear corrective lenses, such as glasses or contact lenses, to achieve clear distance vision. Recognizing this condition is important for proper eye care and when assessing vision needs for various activities, such as driving or watching presentations.

The other choices represent different aspects of vision that do not accurately describe myopia. For instance, having 20/20 vision is considered normal vision, while farsightedness refers to hyperopia, where distant objects are seen more clearly than nearby ones. The term 20/40 vision signifies a level of visual acuity that is less than perfect but is not synonymous with myopia. Thus, the identification of myopia as nearsightedness is crucial in understanding its characteristics and implications for eye health.
