Question

-this can be achieved using corrective lenses or glasses -this is necessary for reading road signs and identifying potential hazards -this is defined as the ability to see clearly and distinctly

Answer 1

Corrective lenses or glasses are used to achieve clear and distinct vision, which is critical for tasks like reading road signs. Myopia and hyperopia are common vision defects that can be corrected with diverging and converging lenses, respectively.

Step-by-step explanation:

The ability to see clearly and distinctly is often achieved through the use of corrective lenses or glasses. This ability is essential for tasks such as reading road signs and identifying potential hazards while driving. For instance, someone with nearsightedness (myopia) has the ability to see near objects clearly, but distant objects appear blurred.

Conversely, farsightedness (hyperopia) is when distant objects can be seen clearly and distinctly, but close objects are not in focus. Corrective lenses are used to adjust the convergence of light rays in the eye, thereby allowing images to be seen clearly. Specifically, a diverging lens is used for myopia to decrease the eye's optical power, while a converging lens for hyperopia increases the optical power.
