What is nearsightedness medically known as?

Nearsightedness, or the inability to see distant objects clearly while nearby objects can be seen well, is medically referred to as myopia. This condition arises when the eyeball is slightly longer than normal, causing light rays to focus in front of the retina instead of directly on its surface. As a result, distant images appear blurred while close objects can be seen distinctly. Understanding myopia is essential for appropriate correction methods, such as glasses or contact lenses that help refocus light correctly onto the retina for clearer vision. Other terms like hyperopia, astigmatism, and presbyopia refer to different vision issues, such as farsightedness and irregular curvature of the lens or cornea, which do not pertain to the specific condition of nearsightedness.
