How is nearsightedness more commonly known?

Nearsightedness is more commonly known as myopia. This condition occurs when the eyeball is slightly elongated or the cornea has too much curvature, causing light rays to focus in front of the retina rather than directly on it. As a result, distant objects appear blurry while close objects can be seen clearly. Understanding myopia is essential for recognizing how it affects vision and the need for corrective lenses or other treatments.

Astigmatism, hyperopia, and presbyopia refer to different visual impairments. Astigmatism involves an irregular shape of the cornea or lens, leading to distorted or blurred vision at all distances. Hyperopia, or farsightedness, occurs when distant objects can be seen more clearly than close ones due to the light focusing behind the retina. Presbyopia is an age-related condition that affects the ability to focus on near tasks as the lens becomes less flexible. Each of these conditions has distinct characteristics separate from myopia.
