Final answer:
To correct short-sightedness, a person can use corrective lenses or undergo refractive surgery.
Step-by-step explanation:
Short-sightedness, or myopia, is a common vision problem where a person can see objects clearly up close, but has difficulty seeing objects in the distance. To correct this defect, a short-sighted person can use corrective lenses such as glasses or contact lenses. These lenses help to focus the light onto the retina, allowing the person to see distant objects more clearly. Another option is refractive surgery, such as LASIK, which reshapes the cornea to correct the refractive error.
