Cats are neither farsighted nor nearsighted, and their vision is actually much better than humans. Cats' eye structure and visual system give them excellent vision. They have a wide field of vision and can see much of their surroundings. Cats' eyes also have good night vision, which allows them to see objects clearly in low-light conditions.

However, compared with human vision, cats' eyes may be defective in some aspects different. For example, cats may have a relatively weak ability to focus on close objects, which means they may not be able to see close details as clearly as humans.

Overall, cats’ vision is adapted to their hunting and survival needs, allowing them to effectively perceive and respond to their surroundings in a variety of environments.
