Understanding Concave Lenses and Their Role in Correcting Nearsightedness

Concave lenses are crucial for individuals who are nearsighted, as they help improve vision by bending light rays outward. This adjustment allows the focused image to reach the back of the eye rather than in front of it. Understanding the mechanics of how concave lenses work can clarify their importance in vision correction for those struggling to see distant objects clearly. When using these lenses, light rays are redirected effectively, enhancing visual clarity and comfort for nearsighted individuals.

  5. 5. People who cannot see distant objects very well are nearsighted. They usually are given concave lenses to improve their vision. Which statement best describes how concave lenses improve their vision? A) The lenses bend light rays outward to focus the image on the back of the eye instead of behind it. B) The lenses reflect light rays inward to focus the image on the back of the eye instead of behind it. C) The lenses bend light rays outward to focus the image on the back of the eye instead of in front of it. D) The lenses reflect light rays inward to focus the image on the back of the eye instead of in front of it.
