When a person is nearsighted, what happens in the eye when the person is looking at something far away? How is this condition \(\mathrm{com}\) monly corrected?

Question: Explain the phenomenon of nearsightedness in an individual when looking at something far away, and discuss the common correction for this condition. Answer: Nearsightedness, or myopia, occurs when a person can see nearby objects clearly but has trouble focusing on distant objects. This is due to the light rays being focused in front of the retina, instead of directly on it. When a nearsighted person looks at distant objects, the light rays converge before reaching the retina, resulting in a blurry image. The common correction for nearsightedness involves using concave lenses in eyeglasses or contact lenses, which diverge the incoming light rays, allowing them to focus directly onto the retina. This results in a clearer image of distant objects. In some cases, refractive surgery such as LASIK or PRK may be recommended as a more permanent solution.
